Multi-Environment Deployment Workflow with env zero's Terraform Provider

The new env zero Agent CLI is available now. Ask your coding agent about your infrastructure in plain English, and it answers from real state, inside the same roles, approvals, and audit trail your team already runs on.

Important Note: The old CLI, the Node package @env0/cli version 1.x, is deprecated. The current CLI is a single binary and is the recommended way to use env zero from the terminal. Pin @env0/cli@^1 to stay on the old one while you migrate.

Today we are launching the Agentic Experience (AX) on env zero, powered by the new env zero Agent CLI. The idea is simple. You point your coding agent, whether that is Claude Code, Cursor, Codex, or Copilot, at your env zero infrastructure, ask it a question in plain English, and it answers from your real environments, deployments, and drift instead of guessing. It is available to every account starting now.

Coding agents are already inside your workflow. They read your codebase, propose changes, and increasingly get asked to do the work rather than describe it. The open question is what they are plugged into when they try. Point one at your infrastructure today and, on most platforms, it sees a thin slice of current state, fills the gaps with guesses, and burns tokens scraping an API that was never meant for a machine to reason over. It can talk about your infrastructure. It cannot reliably operate it.

The Agent CLI changes what the agent is standing on. It gives your agent the full picture, every environment, module, template, plan, and the deployment history behind them, in a form built for a context window instead of a browser tab. Ask a question, and the agent reads real state to answer it. Ask for a change, and it acts through the same roles and approvals a person would. The commands in this post are the plumbing. The product is the conversation on top of them.

Ask your infrastructure a question

Here is what the Agentic Experience looks like in practice. Each example is a prompt an engineer types to their agent. Underneath each one is the command the agent actually runs, the receipt for what it did. You never have to type the command yourself.

"Why did payments-staging go red? Is it our change or drift?"

The agent pulls the environment's full context, its state, recent deployments, and a drift or failure summary, in a single request, then tells you whether the failure traces to your last deploy or to something that changed underneath it.

env0 context payments-staging

‍

"Before I merge this, plan the change against prod and tell me if anything gets replaced."

The agent starts an approval-gated deployment, so the plan runs but nothing applies without a human. It reads the plan, flags any resource that would be replaced rather than updated, and leaves the change waiting for your sign-off.

env0 environment deploy prod --requires-approval

‍

"Which environments in data-platform haven't deployed in 30 days, and what are they costing us?"

The agent lists every environment in the project as structured data, filters by last deployment date, and adds up the cost estimates, so you get the stale environments and their spend in one answer.

env0 environment list --project data-platform -o json

‍

"Anything waiting on my approval? Summarize what each one changes."

The agent finds the deployments paused at an approval gate, reads each plan, and gives you a one-line summary of what every pending change would do before you approve or cancel it.

env0 deployment list -o json

‍

None of these require you to know the commands, and that is the point. The Agent CLI hands the agent structured JSON on stdout, errors on stderr, and stable exit codes, so it can chain reads and actions and know exactly what happened at each step without you translating between English and the API.

Governance that already applies to agents

This is the part security teams care about, and it works today.

An agent on the Agent CLI is not a special case that sits outside your controls. It authenticates as a real env zero identity, per user through the browser or per service through an API key, never a shared token, so every read and every action is attributable to someone rather than fired anonymously.

Because your existing role-based access control applies to that identity, you decide what the agent can do simply by choosing the identity you give it. Hand it a read-scoped identity and you get an agent that can diagnose anything and change nothing. It can pull context, list environments, and read plans and logs, while deploy, destroy, and approve are not available to it at all. Give it a broader identity and the approval gates still hold. A deployment that requires approval pauses for a human no matter who or what started it, and destroying infrastructure still takes an explicit confirmation.

So the safe pattern is available now, with no new product to adopt. A read-only agent that investigates and explains, a human in the loop for anything that changes infrastructure, and a full audit trail, because the agent acted as itself and not as a key nobody can trace.

The skill is the seed of your agent operating policy

Getting an agent set up is one command.

env0 skill install

‍

‍

That writes a usage guide into your coding agent's config so it knows the exact commands, flags, and output formats for the version of the Agent CLI you have installed. It sets up Claude Code by default, with --agent cursor, --agent codex, or --agent copilot for the others.

Two things about that guide matter more than they first appear.

It is version-matched. The agent works from the command surface you actually have, not one it half-remembers from training. Invented flags are the fastest way for an agent to lose an engineer's trust on infrastructure, and a version-matched guide is how you keep them out.

And it is a file in your repository, not a hosted black box. You commit it, and you extend it. Add your own conventions on top: the golden-path templates a new environment should start from, a rule that no agent touches prod without approval, a list of projects that are off limits. Once it is committed, every agent that every engineer runs inherits the same operating manual, and it gets reviewed in a pull request like any other code. You are not just installing a skill. You are planting the seed of your team's agent operating policy, in version control, where it belongs.

Why it goes deeper than an API wrapper

A generic CLI wrapped around an API is only as good as the API underneath it. env zero already understands your environments, your modules, your deployment history, and how they connect, and the Agent CLI is built on that understanding rather than layered over it.

The clearest example is env0 context. It returns an environment's state, recent deployments, and drift or failure summary in a single call, so an agent diagnoses a broken deployment in one request instead of stitching the picture together across several. Fewer round trips, less context spent, and an answer grounded in real state.

It also clears the three obstacles we heard about from nearly every team that tried to put agent access in front of a platform. Security teams distrusted a shared, unattributable credential. One enterprise customer's security team blocked our old MCP server outright and started patching around the credential model before they ever raised it with us. Setup was a wall. As one account team put it while describing the self-hosted container, four out of five customers got stuck standing it up. And even where it worked, the surface underneath was thin, showing the latest deployment only, with no history. The Agent CLI answers all three. There is no container to stand up, a real per-identity login replaces the shared token, and the surface is deep enough that an agent never has to fall back to the raw API for context.

The old MCP server keeps working for existing integrations, but new agent capability lands in the Agent CLI now. That is where the Agentic Experience lives going forward.

What's in this release

• Point Claude Code, Cursor, Codex, or Copilot at env zero and ask about your infrastructure in plain English
• Read across environments, deployments, projects, templates, and plans, including full history
• Diagnose a failed environment (state, recent deployments, and drift) in a single env0 context call
• Run core actions when you allow it: create, deploy, destroy, approve, cancel, abort
• Scope agents with your existing roles and approvals, with every action attributable to a real identity
• See cost estimates alongside your reads
• Install a version-matched, extensible skill for your agent with one command

What comes next

Today you scope an agent by choosing the identity you give it. Next, we are making read-only the default for agents regardless of the human behind them, with write access as an explicit, audited step someone has to grant. An engineer with full permissions still gets a read-only agent unless they deliberately elevate it.

We are also expanding what an agent can see, starting with policy and governance configuration, so it can read the guardrails a project runs under and not just its deployments, and we are widening the read surface from there.

The goal has not changed. Give an agent enough real context to be useful, and never more access than it has earned.

FAQ

What is the env zero Agentic Experience? It is the ability to point a coding agent, such as Claude Code, Cursor, Codex, or Copilot, at your env zero infrastructure and work with it in plain English. The agent answers from your real environments, deployments, and drift, and can take action through the same roles and approvals a person would. It is powered by the new env zero Agent CLI, available now.

How is this different from the old MCP server? The MCP server needed a self-hosted container and a single shared credential, and it only ever saw the latest deployment. The Agent CLI installs directly as a single binary, authenticates per user or per service account, reads the full history and diagnosis surface, and returns structured output an agent can parse without extra tooling. The MCP server keeps working for existing integrations, but new agent capability lands in the Agent CLI.

Can I stop an agent from changing infrastructure? Yes, today. An agent authenticates as a real env zero identity and inherits that identity's role. Give it a read-scoped identity and it can diagnose but not deploy, destroy, or approve. Even with a broader identity, approval gates still pause changes for a human, and every action is recorded against the identity that ran it.

What exactly does the skill do? env0 skill install writes a version-matched usage guide into your agent's config so it knows the real commands and flags for the CLI you have installed, which keeps it from inventing them. Because the guide is a file in your repository, you can commit it and extend it with your own conventions, so every engineer's agent inherits the same rules.

What is on the roadmap? Read-only-by-default access for agents regardless of the human behind them, with an explicit, audited path to write access, broader policy and governance visibility in the CLI, and continued expansion of the read surface.

Important Note: @env0/cli version 1.x, is deprecated. The current CLI is a single binary and is the recommended way to use env zero from the terminal. Pin @env0/cli@^1 to stay on the old one while you migrate. Please see details on the new env zero CLI here.

At envzero we know how important workflows are for developers, which is why we’re excited to announce the brand new envzero CLI! Just like our GUI at envzero.com and our API, you can make use of the features and capabilities of envzero through the CLI to build your own perfect workflow.

Why a CLI? As your system becomes more robust and complex, you may often find yourself working with different service providers and 3rd-parties to assist your dev team. Whether it’s your cloud provider, different security-related solutions or CI/CD platforms, they usually provide you with a decent user interface to handle your requirements and actions. As time goes by, you could find yourself wanting a better degree of automation to your day to day operations. A CLI is a great way to do all this without ever having to change context or even take your hands off the keyboard.

And because we’re big supporters of Open Source and believe in sharing our code with the world, we’re proud to say that our CLI is fully open-sourced. The CLI can be found on GitHub and is published via npm and you’re welcome to leave your feedback and contribute.

Setting Up the CLI

First, we need to verify that NodeJS (a dependency for the CLI) is installed and that we can globally install our package:

npm install -g @env0/cli
// or
yarn global add @env0/cli

After installing the command line tool, we need to head over to the envzero UI to create a new API key and secret for our CLI usage. You can find it under the Organization -> Settings -> API Keys screen.

Now we need to configure the CLI tool with proper settings and secrets using the envzero configure command:

If you aren’t aware of your organization, project and blueprint IDs — don’t worry! Head over to app.envzero.com and follow our walk through to learn about the different entities in the flow.

Now that we have a properly configured CLI, we can run our first deployment using the envzero deploy command, or have our existing environment taken off using the envzero destroy command!

Using the CLI

Once your CLI is set up, you can use it to easily manage your cloud environments from your local machine, while maintaining all the governance and visibility that envzero gives you. What can you do with the CLI?

Deploy/Destroy

Deploy or destroy your environments using

envzero deploy
// or
envzero destroy

And just wait a little to see your live deployment getting updated on your console’s output!

Plan/Approve Plan

Another common practice in the envzero platform is to run your deployment where it’ll wait for an approval before applying actual changes. This flow is also achievable via the new CLI using the - requiresApproval (-a) argument.

envzero deploy -a
// or
envzero destroy -a

Your deployment will halt and wait for approval before continuing. In order to approve or cancel your current environment’s deployment you can use either of the commands:

envzero approve
// or
envzero cancel

For extensive information on how to use the above commands please approach the envzero CLI official README.

Streamlined Deployment Steps Logs

When dealing with deployments, the most interesting view is the console output that shows your deployment logs. On the envzero platform, you already get an organized and detailed view of your deployment logs, divided into predefined steps (i.e git clone, terraform init, terraform plan/apply and etc.)

The envzero CLI keeps the same experience with streamlined deployment steps logs that are sent to your console right away and gives you a live view of your deployment status.

You run [.code]terraform apply[.code], it fails partway through, and the next command you run refuses to move: [.code]Error acquiring the state lock[.code]. Nothing is broken yet, but nothing will proceed either until the lock is cleared.

This guide covers what [.code]force-unlock[.code] actually does, when it is safe to use, how to find the lock ID on every major backend, and what to do if the command itself does not fix things.

What does terraform force-unlock do?

Terraform locks state before any operation that could write to it. The lock stops two processes from writing to the same state file at once, which is the most common way a state file gets corrupted. Locking happens automatically and silently on every plan and apply where the backend supports it. You will not see a message unless acquiring the lock takes longer than expected.

[.code]force-unlock[.code] is the manual override for when that automatic process gets stuck. It removes the lock record so a new operation can proceed. According to HashiCorp, the command does not modify your infrastructure, and on most backends it does not touch your state data either. It just clears the record that says the state is currently held.

Usage:

terraform force-unlock [options] LOCK_ID

The only option is [.code]-force[.code], which skips the yes or no confirmation prompt. That is useful inside a script or CI job where nothing is available to type “yes” into. Otherwise leave it off, since the confirmation step is the last chance to catch a mistake before you unlock something someone else is actively using.

The lock ID is not optional and is not guessable. Terraform prints it in the error message when a lock is already held, and [.code]force-unlock[.code] requires an exact match. Per HashiCorp's own documentation, the ID works as a nonce, a one-time verification token that ensures a lock and an unlock target the same lock. That is deliberate: you can only release a lock you can identify, not just any lock on the state file.

One thing worth flagging up front: on the local backend, a stuck lock can only be cleared by the same machine and user that created it. There is no separate process to force it from elsewhere, which is one more reason most teams move to a remote backend, such as the ones covered in this backend configuration guide, before this becomes a live problem.

When should you use the force-unlock command?

Treat [.code]force-unlock[.code] as a last resort, not a first response. If two operations are genuinely running against the same state at the same time, forcing a lock open defeats the entire purpose of state locking and can leave you with a corrupted state file. Only run it when you are certain the process that created the lock is no longer active.

A stuck lock usually traces back to one of a few causes:

• A [.code]terraform apply[.code] or [.code]plan[.code] was cancelled or errored mid-run, for example because a CI job timed out or someone hit Ctrl+C, so Terraform never reached the step where it releases the lock.
• The machine or build agent running Terraform lost its network connection to the backend before the lock could be released.
• The backend storage itself changed mid-operation, for example a Terraform run modifying firewall rules, private endpoints, or access policies on the very storage account that holds the state file.

If none of those match your situation and you are not sure why the lock exists, treat that as a reason to investigate before clearing it, not a reason to assume it is safe to force.

Where to find the lock ID for every backend

In most cases you will not need to go looking. The lock ID appears directly in the [.code]Error acquiring the state lock[.code] message, under the [.code]ID:[.code] field, alongside who holds it and when it was created. The backend-specific detail below matters mainly when you are troubleshooting secondhand, for example clearing a lock a teammate reported without a fresh error message in front of you.

Local backend

Terraform writes a [.code].terraform.tfstate.lock.info[.code] file next to the state file while an operation is in progress. It is a small JSON object containing the lock [.code]ID[.code], the operation type, and who created it. On clean exit, Terraform deletes this file automatically. As noted above, a lock created by one machine cannot be released by [.code]force-unlock[.code] from a different one.

Amazon S3

As of Terraform 1.11, the S3 backend supports native state locking through the [.code]use_lockfile[.code] argument, and no longer requires a separate DynamoDB table. Setting it to [.code]true[.code] tells Terraform to create a lock object in the same S3 bucket as your state, using conditional writes so only one process can create it at a time.

terraform {
  backend "s3" {
    bucket       = "mybucket"
    key          = "path/to/my/key"
    region       = "us-east-1"
    use_lockfile = true
  }
}

With native locking, the lock ID is whatever the error message reports; there is no separate table to query. If your configuration still uses the older [.code]dynamodb_table[.code] argument, note that HashiCorp has deprecated it in favor of [.code]use_lockfile[.code]. On that legacy path, the lock lives as an item in the DynamoDB table, keyed by a partition key named [.code]LockID[.code], and you can inspect it directly:

aws dynamodb get-item \
  --table-name your-lock-table \
  --key '{"LockID": {"S": "your-bucket/path/to/terraform.tfstate"}}'

Azure Blob Storage

Azure Blob Storage implements locking through native blob leases, with no extra backend configuration required. If a run is interrupted mid-apply, the lease can be left in place. The lock ID appears in the error message, but you can also inspect the lease state directly:

az storage blob show \
  --account-name YOUR_STORAGE_ACCOUNT \
  --container-name YOUR_CONTAINER \
  --name path/to/terraform.tfstate \
  --query 'properties.lease'

If [.code]force-unlock[.code] is not an option, for example the lock ID is unavailable, you can break the lease directly through the Azure CLI, which achieves the same result at the storage layer:

az storage blob lease break \
  --account-name YOUR_STORAGE_ACCOUNT \
  --container-name YOUR_CONTAINER \
  --blob-name path/to/terraform.tfstate

Google Cloud Storage

The GCS backend also locks natively with zero extra configuration. Terraform writes a lock object at [.code]/.tflock[.code] in the same bucket as your state, and the lock ID is the object's generation number, which is included in the error message. Deleting that object directly is the manual equivalent of [.code]force-unlock[.code] if the CLI command fails for some reason.

HCP Terraform and Terraform Enterprise

This is a common point of confusion: [.code]terraform force-unlock[.code] is a CLI command that works against backends where Terraform itself manages the lock file. HCP Terraform and Terraform Enterprise instead lock and unlock workspaces through their own UI and API, not the CLI command. In the workspace's Actions menu, you can select Lock workspace or Unlock workspace directly, or call the workspaces API endpoint to do the same thing from automation.

Consul

With the Consul backend, lock information lives in the Consul key-value store rather than in a file. You can list it with the [.code]consul kv get [.code] command, or query the same data through Consul's HTTP API.

Using terraform force-unlock: a worked example

1. Identify the lock ID from the error message. For example: [.code]Lock Info: ID: b8814894-4a5f-217b-e97b-c4f5c02a1f88[.code].
2. Confirm nobody else is running an operation against this state. Check your CI/CD dashboard, ask your team, or check the environment's deployment history if you are running on a platform that centralizes this, before assuming the lock is actually stale.
3. Run the command with the ID from step one: [.code]terraform force-unlock b8814894-4a5f-217b-e97b-c4f5c02a1f88[.code]. Confirm the prompt with [.code]yes[.code], or add [.code]-force[.code] if you are running this non-interactively.
4. Verify the fix by re-running the command that originally failed, such as [.code]terraform plan[.code]. If it proceeds past the locking step without error, the lock is cleared.

Unlocking remote state: alternatives to force-unlock

Wait instead of forcing: -lock-timeout

If two operations occasionally overlap for a few seconds, for example two CI jobs kicking off close together, [.code]force-unlock[.code] is the wrong tool. The [.code]-lock-timeout[.code] flag tells Terraform to wait for the lock to clear on its own instead of failing immediately:

terraform plan -lock-timeout=5m

This is worth setting as a default in CI pipelines that run plan, apply, or destroy operations back to back, so a brief overlap resolves itself instead of surfacing as a lock error at all.

Manual removal as a last resort

Occasionally [.code]force-unlock[.code] itself fails, usually because the backend is unreachable or credentials cannot reach the lock record. HashiCorp's guide to recovering state from backup covers this scenario directly. In that situation, the remaining options are backend-specific: delete the lock object from S3 or GCS, edit or remove the DynamoDB item, or break the Azure blob lease as shown above. All of these bypass Terraform entirely, so treat them with the same caution as [.code]force-unlock[.code] itself.

Coordinate before you unlock

Whichever method you use, confirm no other process is mid-write before you touch the lock, and consider pulling a backup first with [.code]terraform state pull[.code]. Never use [.code]-lock=false[.code] as a standing workaround for frequent lock errors. It disables the protection entirely rather than resolving whatever is causing the contention.

Troubleshooting force-unlock errors

The lock ID does not match

[.code]force-unlock[.code] will refuse an ID that does not match the current lock. This almost always means you are using a stale ID from an old error message. Re-run the failing command to get the current lock's ID and try again.

Permission errors during force-unlock

Clearing a lock requires write or delete access to wherever the lock record lives, for example [.code]s3:DeleteObject[.code] on the lock object, or the equivalent DynamoDB, GCS, or Azure permission. A permissions error here usually points to the credentials Terraform is running with, not the lock itself.

The same lock error comes back immediately

If you clear a lock and it reappears right away, something is still actively writing to that state. Stop and investigate before unlocking again. This pattern usually means step two of the worked example above was skipped.

Managing state locking at scale with env zero

Clearing a stuck lock by hand does not scale once a platform team is managing hundreds of environments across multiple backends. Ad Hoc Tasks in env zero let you run a command, including [.code]terraform force-unlock -force LOCK_ID[.code], directly on the environment's deployment container from the UI. That means resolving a stuck lock does not require local CLI access, a checked-out copy of the Terraform configuration, or direct credentials to the backend that holds the state.

By default, ad hoc tasks are restricted to organization administrators, since they allow arbitrary commands against a live deployment container. Teams that want to delegate lock-clearing to platform engineers without granting full admin access can do that with a custom role scoped to just that permission.

It is worth distinguishing this from Environment Locking in env zero, which is a separate, deliberate governance control rather than Terraform's automatic state lock. Locking an environment in env zero blocks deploys, destroys, plans, and drift detection outright, with a reason attached for anyone else who looks at it, and it stays in effect until someone with permission unlocks it. A Terraform state lock, by contrast, is transient by design and normally clears itself within seconds. If you are troubleshooting a “locked” environment in env zero and [.code]force-unlock[.code] does not seem relevant, this distinction is usually why.

Key takeaways

• [.code]terraform force-unlock LOCK_ID[.code] manually clears a stuck state lock. It does not touch your infrastructure, and on most backends it does not touch your state data either.
• Only use it when you are certain the process that created the lock is no longer running. Unlocking an active operation risks a corrupted state file.
• The lock ID is usually sitting right in the error message. You only need to hunt through backend-specific tooling when troubleshooting without that message in hand.
• S3 no longer needs DynamoDB for locking. [.code]use_lockfile = true[.code] has been the supported path since Terraform 1.11.
• [.code]-lock-timeout[.code] prevents most stuck-lock situations in CI before they happen, by waiting instead of failing immediately.

Frequently asked questions

Q. How do I fix a Terraform state lock?

Run [.code]terraform force-unlock LOCK_ID[.code], using the ID from the [.code]Error acquiring the state lock[.code] message. Only do this once you are certain no other operation is currently running against the same state.

Q. What is Terraform state locking for?

State locking prevents two operations from writing to the same state file at the same time, which is one of the most common causes of state corruption. Terraform acquires the lock automatically before any operation that could write state and releases it when the operation finishes.

Q. Can force-unlock corrupt my Terraform state?

[.code]force-unlock[.code] itself does not modify your infrastructure or your state data; it only removes the lock record. The risk is indirect: if you unlock a state that another process is actively writing to, that process and yours can both write at once, which can corrupt the state file.

Q. Does the S3 backend still need DynamoDB for state locking?

No. Since Terraform 1.11, the S3 backend supports native locking through [.code]use_lockfile = true[.code], using S3 conditional writes instead of a separate DynamoDB table. The older [.code]dynamodb_table[.code] argument still works but is deprecated.

Q. How do I avoid stuck state locks in the first place?

Avoid cancelling Terraform runs mid-operation, set [.code]-lock-timeout[.code] in CI so brief overlaps wait instead of failing, and use a platform that centralizes deployment history so you can quickly confirm whether a lock is stale before clearing it.

Hello, env zero fans! As some of you know, we have almost unlimited extensibility with 3rd party tools, using our custom workflows. You can hook in pretty much any tool, in any phase of the deployment. Today, we’re going to talk about how to prevent cloud misconfigurations before they start. We’re going to do this by chaining a tool in the deployment after the terraform plan phase. This is where our friends at Bridgecrew come in. Just like we at env zero have open-sourced the Terratag module of our platform, Bridgecrew has open-sourced Checkov!

Checkov

Checkov is a static code analysis tool for infrastructure-as-code. It scans cloud infrastructure managed in Terraform, Cloudformation, Kubernetes, Arm templates, or Serverless Framework and detects misconfigurations.

Setup

For illustration purposes, we’re going to use Bridgecrew’s demo application called TerraGoat. TerraGoat is Bridgecrew’s “Vulnerable by Design” Terraform repository. TerraGoat is a learning and training project that demonstrates how common configuration errors can find their way into production cloud environments.

DISCLAIMER: DO NOT ACTUALLY DEPLOY THIS APPLICATION INTO YOUR CLOUD INFRASTRUCTURE. IT IS PURPOSELY COMPROMISED.

I have created a template of TerraGoat inside of env zero and linked it to our Bridgecrew Demo project.

The only other thing we have to do is to actually call Checkov to do the check during the deployment. We need to do this after the Terraform plan phase, so that we have a plan to check. Here is what the env0.yml file will look like:

This adds 3 commands that run after the Terraform Plan, and before Terraform Apply. We put it here so that the Apply doesn’t run in case of failures. We don’t want to see the errors after the resources are applied. We want the deployment to fail if there are errors.

This command installs Checkov into our runtime environment using the pip3 package installer so we can run it against our Terraform plan.

This command essentially formats our .tf-plan file into tf.json so that it can be parsed and run against Checkov.

This command has a lot going on and is in 2 parts. First, it quietly executes Checkov against our tf.json (the reformatted tf.plan file) and looks for a 0 exit code. The double pipe || tells bash to only execute the 2nd command if the exit code of the first command is not 0. So if your Checkov results are clear, your deployment gets the 0 exit code and continues on with the deployment.

If not, then the second part of the command runs. Knowing if this part runs, it is because of a failure, we’re just going to format our error message here. We run Checkov again so we can pipe the error with the echoed error notification text to the console. The 1>&2 routs stdout to stderror, and the exit 1 code tells env zero that the stage failed, and to end the deployment run.

The env zero platform will parse the error, and give you the clear error printed on the Environment deployment page. But, if you want the full logs from Checkov, you can find those in the After: Terraform Plan deployment logs.

And that’s it! A little bit of YAML, and you’ve implemented Checkov to protect yourself against the deployment of misconfigured cloud resources. That is instantly added value to your organization by shifting the security left in your deployment process with env0.

You can find more information on Checkov here. You can find the open-source repository on GitHub. And be sure to see how you can automate your infrastructure security from commit to cloud at Bridgecrew.io.

"env zero cut our mean time to merge in half by helping us better manage our workflow and code conflicts.Their customer service and willingness to roll out features based on our needs was unprecedented."

Troy Knapp

Senior DevOps Engineery

‍

Background

Zip Co Limited (abbreviated as Zip Co) is a global 'buy now pay later' financial technology company with operations in Australia, New Zealand, and the USA used by millions of customers to handle billions of dollars in annual transactions. 

The Challenge

Before using env0, ZipCo utilized a monolithic Terraform repository and a rigid tool that functioned similarly to a conventional Git workflow, involving numerous pull requests from the master branch.

This resulted in a cumbersome process that ended up locking out any other developer from making changes. 

Moreover, for change, the propagation occurred linearly, where each environment would update one by one, further lengthening the time to deploy. 

As a result, it wasn’t uncommon for a simple change to take multiple hours to deploy, during which the codebase was locked, preventing anyone else from working on it.

The Solution

• Parallel Deployments: Before env0, ZipCo would have to deploy their code linearly. After moving to env0, multiple environments could now be deployed simultaneously.
• Robust UI: The interface env zero provides has given each developer a deeper insight in a much more organized fashion that doesn't rely on local code execution. The interface is also much easier to understand, well documented, and has fewer clicks than their previous solution.

The Impact

• Time to Deploy Cut by 50% - Simultaneous environment deployments have drastically reduced deployment times, thereby optimizing the development cycle and saving valuable time for the company.  
• Transparency and Accountability - By exposing "tribal knowledge" and eliminating hidden shortcuts and backdoors, all team members now have a clear understanding of the deployment environments, fostering a culture of openness and accountability.
• Streamlined Operations - The UI simplifies the deployment process, requires fewer steps compared to previous solutions, and is more intuitive. This improvement has enhanced productivity.
• Shortening Issue Resolution - Using env zero drift detection and logging capabilities, issues could be identified and resolved quicker, within hours rather than days or weeks.

What’s Next

There are still daily challenges ZipCo faces as they continue to integrate their worldwide Azure solution with env0. As each challenge presents itself, the flexibility of env zero coupled with the newfound agility gives ZipCo multiple paths to solve issues they traditionally saw as not reasonably achievable.
