You Need Audit Logs for Your Infrastructure as Code, and They’re Easy to Set Up

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.

Using the envzero CLI lets you and your team enjoy the convenience of a local CLI with all the automation, governance, and visibility that envzero brings for your environments and their deployments. Feel free to test it out and provide us with feedback!

You may also follow our detailed README for a full list of the commands and their available arguments.

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.

This quick video talks about the static code analysis tool, Checkov by Bridgecrew. We'll use it to fix a problem with a Terraform deployment into Azure. Be sure to star their repository if you like the project.

“All these investments in DevOps and developer productivity and operational efficiency are bottlenecking in these environments on security and compliance.”

This was an observation from Andrew Clay Shafer in a fireside chat with John Willis at DevOps Days Dallas 2022. One such bottleneck can come in the form of audit logs, but auditability doesn’t have to be a blocker. 

In this post we’ll take a look at why auditing is necessary for Infrastructure as Code, the benefits of having an audit trail for Terraform and other IaC frameworks (such as Terragrunt, Pulumi, CloudFormation, Kubernetes, and others), and share how you can automate your audit trail easily with env0.

How do you audit Infrastructure as Code? 

All you need is a central log management system that can aggregate and parse your audit. env zero delivers a number of benefits for auditability:

• Changes to infrastructure are tracked in the code repository, making it easy to see who made what changes and when.
• Automatically roll back changes that cause problems.
• Audit changes made by third-party vendors.

Audit log walkthrough 

There are two ways to access audit logs in env0, 1) through the UI, and 2) through the API. As always, env zero gives you the flexibility to interact with your infrastructure-as-code as it suits your organization, be it programmatically or through a simple user interface. Only an Admin user can access the Audit Logs.

The audit log contains information about who performed the activity, when the action was performed, the activity’s description, and additional data like their IP address.

The audit log shows events related to changes in your:

• Organization
• Projects
• Templates
• Environments
• Teams
• Users
• Roles
• Modules
• Git Tokens
• Cloud credentials
• API keys
• SSH keys
• Variables
• Agent configurations

Through the env zero UI

1. Go to the Organization's Settings page.
2. Click the Audit Logs tab.
3. The audit details are listed in a table.
4. Click the row's + sign to reveal additional activity details.
5. Click the Show more button at the bottom of the page to see more rows.

Through the env zero API

Use the "Fetch Audit Logs" API to retrieve your organization's audit logs programmatically. Learn more about the audit log in our documentation.

Use an audit log for governance and compliance

With this latest release, we’re continuing to deliver the enterprise-level capabilities to enable DevOps, Platform, and Infrastructure as Code teams to deliver secure software faster while ensuring compliance with internal policies or external regulations. env zero has clearly auditable versioning of infrastructure changes, giving you the answer to questions like, “What was changed, who changed it, and when was it changed?” 

We help you avoid the audit and compliance bottleneck, so you can focus on what’s important—shipping software.

In a recent blog post, I discussed expanding the idea of “Feature branches” to “Feature environments”. Using Infrastructure-as-Code, we can create an environment for every feature we are working on, thereby giving us a more flexible, isolated development environment, and allowing us to test our code early in the development process.

In this post I’d like to continue down that path, and see how we can automatically create an environment for every pull request, and gain a number of advantages over traditional static staging or qa environments.

Pull Requests & Moving Beyond Static Staging

Pull requests are a well known and common workflow step for many development teams. We usually think of them as a way you “tell others about changes you've pushed”, and where you “can discuss and review the potential changes with collaborators and add follow-up commits before your changes are merged”.

PR’s are more than just a code review - they’re a milestone in a feature’s lifecycle and a way of saying “I’m ready for this to be shared”. Beyond sharing it for feedback with the wider team, this milestone is a critical time to ensure it functions exactly as expected as part of the whole application, including any potential infrastructure or configuration changes. However - just as we wouldn’t want our data migration to run on the shared database at this point, we also want to use dedicated test infrastructure.

Static VS Dynamic PR Environments

At this point, you might ask yourself - I’m already testing my code and infrastructure changes in our dev/qa/staging environment, why complicate things?

Well, there are a number of advantages to moving from traditional, static environments, to dynamic, per-pull-request environments:

• They’re Isolated and Dedicated - having a dedicated environment for each PR means no more confusion of which version or branch is currently in staging, and no coordinating between people who want to test different versions.
• Easier To Share - Because each PR has its own fully functional environment, non technical stakeholders can provide feedback on new features very early in the process. Developers can then iterate over this feedback - without interfering with work being done by other team members.
• No Wasted Resources - Because you’re only provisioning an environment when you actually need it for testing, you’re not wasting (or paying for) resources when you don’t actually need them.
• Removes Bottlenecks In The Release Cycle - Shared development and staging environments are notorious bottlenecks for development teams, especially when they are the first place where new code meets infrastructure. It’s not uncommon to see a queue of who is using the environment for testing their features. Your developers time shouldn’t be spent on waiting.

How Do You Actually Do It?

Ok, so “per pull request environments” is an awesome idea. How are we going to actually get there? There are a number of tools out there that can help you accomplish this task but in this post, I’ll be using env0, a first of it’s kind environment-as-a-service platform - not just to deploy the environments, but to manage them as well.

Your default assumption might be to just use your CI/CD platform to set up your environment. This works, but most CI/CD platforms are built for running short lived tasks, whereas an environment’s lifecycle extends beyond deploying it once: It needs to be updated, monitored, and in the end destroyed. Besides easily automating resource provisioning using Terraform, env zero will help me keep track of which environments are up, which ones have had issues, and will provide me a top level view of how my whole team is using these environments.

Besides env0, I’ll be using Github to host my code and open pull requests, and Github Actions to trigger my environment creation. I’ll be using the same code example from the previous post, which will be deployed on AWS.

If you’d like to try this out yourself, the prerequisites for this tutorial will be

• An env zero account (it’s free, just login)
• A Github account 
• An AWS account

Getting Our Hands Dirty

Step one to fully automating anything is to make sure we can run it manually, so you’ll want to get your system set up. In my case, I’ve followed env0’s getting started guide, and taken the key steps of creating my own organization, connecting my AWS account, and creating a template for my Terraform code.

Custom workflows to the rescue

In the example code I’ve used, I also ran a bash script before deploying the environment. We can easily make sure this code runs before our Terraform is applied, using env0’s Custom Flows feature. I’ve already done this in advance and I’ve put my code in the env0.yml file, in our Github repo.

Let ‘er Rip!

We are ready to launch our first environment! Remember - this is just a manual test, to see things are ready for automation.

In the case of env0, just go to your Project Templates pages, and click “Run now” on the template we’ve created before. In the next screen, you can validate your settings, and when you’re ready - click “Run”.

‍

‍

Great!

Integrating into CI/CD

Now that we know our environment management system will properly configure our environments, we need to make it run each time we open a pull request. For that, we’ll be using Github Actions to trigger env0’s CLI.

In order to create an environment on env zero from Github Actions, we need to create an API key for env0.

Next, we’ll need to save the API key and secret as Github Secrets, in the same manner we saved our AWS credentials to env0.

The final step of connecting everything, is telling Github how to trigger our environment deploy. We’ll add the following code to our codebase, in the file `.github/workflows/pr-environments.yml`.

name: "PR Environments"
on:
 pull_request:
   types: [opened, closed, reopened, synchronize]
jobs:
 env0_pr_environment:
   name: "PR Environment"
   runs-on: ubuntu-16.04
   env:
     ACTION: deploy
   steps:
     - name: Set Action
       if: github.event.action == 'closed'
       run: echo "::set-env name=ACTION::destroy"
     - uses: actions/setup-node@v1
       with:
         node-version: '12'
     - uses: actions/checkout@v2
       with:
         repository: env0/env0-client-integrations
     - name: install
       working-directory: node
       run: yarn
     - name: deploy
       working-directory: node
       run: >
         node env0-deploy-cli.js
         --apiKey ${{ secrets.ENV0_API_KEY_ID }}
         --apiSecret ${{ secrets.ENV0_API_KEY_SECRET }}
         --action $ACTION
         --organizationId ${{ secrets.ENV0_ORG_ID }}
         --projectId ${{ secrets.ENV0_PROJECT_ID }}
         --blueprintId ${{ secrets.ENV0_BLUEPRINT_ID }}
         --environmentName "${{ github.head_ref }}"
         --revision "${{ github.head_ref }}"

In the code above, you can see we

• Determine the action depending on the Github event data
• Fetch the env zero CLI, using the `checkout` action
• Run the env zero cli to deploy, update, or destroy the environment
• The name of the environment will be the branch name

That’s all folks!

We now have a fully functioning pipeline, and our setup will automatically create a new environment for every PR we open! When we deploy a new feature, even if that feature requires new or different infrastructure, the changes in our Terraform code will automatically be reflected in the resources provisioned for the PR environment!

In the case of env0, even though environments will be automatically created and destroyed by our CI/CD integration, we can also use the env zero UI as a control plane, for understanding which environments are up, and what they consist of. You can also use env0’s cost monitoring features, to understand how much each of these environments actually costs.

‍

Thank you for taking the time to read this post, I hope it helps you setting an environment-per-PR pipeline for your team. Once you’ve tried it yourself, I’d love to hear about it! Let me know in the comments below or on Twitter at @envzero.
