Deployment

This page covers getting Atlantis up and running in your infrastructure.

Prerequisites

Architecture Overview

Runtime

Atlantis is a simple Goopen in new window app. It receives webhooks from your Git host and executes Terraform commands locally. There is an official Atlantis Docker imageopen in new window.

Routing

Atlantis and your Git host need to be able to route and communicate with one another. Your Git host needs to be able to send webhooks to Atlantis and Atlantis needs to be able to make API calls to your Git host. If you're using a public Git host like github.com, gitlab.com, bitbucket.org, or dev.azure.com then you'll need to expose Atlantis to the internet.

If you're using a private Git host like GitHub Enterprise, GitLab Enterprise or Bitbucket Server, then Atlantis needs to be routable from the private host and Atlantis will need to be able to route to the private host.

Data

Atlantis has no external database. Atlantis stores Terraform plan files on disk. If Atlantis loses that data in between a plan and apply cycle, then users will have to re-run plan. Because of this, you may want to provision a persistent disk for Atlantis.

Deployment

Pick your deployment type:

Kubernetes Helm Chart

Atlantis has an official Helm chartopen in new window

To install:

  1. Add the runatlantis helm chart repository to helm

    helm repo add runatlantis https://runatlantis.github.io/helm-charts
    
  2. cd into a directory where you're going to configure your Atlantis Helm chart

  3. Create a values.yaml file by running

    helm inspect values runatlantis/atlantis > values.yaml
    
  4. Edit values.yaml and add your access credentials and webhook secret

    # for example
    github:
      user: foo
      token: bar
      secret: baz
    
  5. Edit values.yaml and set your orgAllowlist (see Repo Allowlist for more information)

    orgAllowlist: github.com/runatlantis/*
    

    Note: For helm chart version < 4.0.2, orgWhitelist must be used instead.

  6. Configure any other variables (see https://github.com/runatlantis/helm-charts#customizationopen in new window for documentation)

  7. Run

    helm install atlantis runatlantis/atlantis -f values.yaml
    

    If you are using helm v2, run:

    helm install -f values.yaml runatlantis/atlantis
    

Atlantis should be up and running in minutes! See Next Steps for what to do next.

Kubernetes Manifests

If you'd like to use a raw Kubernetes manifest, we offer either a Deploymentopen in new window or a Statefulsetopen in new window with persistent storage.

StatefulSet is recommended because Atlantis stores its data on disk and so if your Pod dies or you upgrade Atlantis, you won't lose plans that haven't been applied. If you do lose that data, you just need to run atlantis plan again so it's not the end of the world.

Regardless of whether you choose a Deployment or StatefulSet, first create a Secret with the webhook secret and access token:

echo -n "yourtoken" > token
echo -n "yoursecret" > webhook-secret
kubectl create secret generic atlantis-vcs --from-file=token --from-file=webhook-secret

Note

If you're using Bitbucket Cloud then there is no webhook secret since it's not supported.

Next, edit the manifests below as follows:

  1. Replace <VERSION> in image: ghcr.io/runatlantis/atlantis:<VERSION> with the most recent version from https://github.com/runatlantis/atlantis/releases/latestopen in new window.
    • NOTE: You never want to run with :latest because if your Pod moves to a new node, Kubernetes will pull the latest image and you might end up upgrading Atlantis by accident!
  2. Replace value: github.com/yourorg/* under name: ATLANTIS_REPO_ALLOWLIST with the allowlist pattern for your Terraform repos. See Repo Allowlist for more details.
  3. If you're using GitHub:
    1. Replace <YOUR_GITHUB_USER> with the username of your Atlantis GitHub user without the @.
    2. Delete all the ATLANTIS_GITLAB_*, ATLANTIS_BITBUCKET_*, and ATLANTIS_AZUREDEVOPS_* environment variables.
  4. If you're using GitLab:
    1. Replace <YOUR_GITLAB_USER> with the username of your Atlantis GitLab user without the @.
    2. Delete all the ATLANTIS_GH_*, ATLANTIS_BITBUCKET_*, and ATLANTIS_AZUREDEVOPS_* environment variables.
  5. If you're using Bitbucket:
    1. Replace <YOUR_BITBUCKET_USER> with the username of your Atlantis Bitbucket user without the @.
    2. Delete all the ATLANTIS_GH_*, ATLANTIS_GITLAB_*, and ATLANTIS_AZUREDEVOPS_* environment variables.
  6. If you're using Azure DevOps:
    1. Replace <YOUR_AZUREDEVOPS_USER> with the username of your Atlantis Azure DevOps user without the @.
    2. Delete all the ATLANTIS_GH_*, ATLANTIS_GITLAB_*, and ATLANTIS_BITBUCKET_* environment variables.

Routing and SSL

The manifests above create a Kubernetes Service of type: ClusterIP which isn't accessible outside your cluster. Depending on how you're doing routing into Kubernetes, you may want to use a Service of type: LoadBalancer so that Atlantis is accessible to GitHub/GitLab and your internal users.

If you want to add SSL you can use something like https://github.com/jetstack/cert-manageropen in new window to generate SSL certs and mount them into the Pod. Then set the ATLANTIS_SSL_CERT_FILE and ATLANTIS_SSL_KEY_FILE environment variables to enable SSL. You could also set up SSL at your LoadBalancer.

You're done! See Next Steps for what to do next.

Kubernetes Kustomize

A kustomization.yaml file is provided in the directory kustomize/, so you may use this repository as a remote base for deploying Atlantis with Kustomize.

You will need to provide a secret (with the default name of atlantis-vcs) to configure Atlantis with access credentials for your remote repositories.

Example:

bases:
- github.com/runatlantis/atlantis//kustomize

resources:
- secrets.yaml

Important: You must ensure you patch the provided manifests with the correct environment variables for your installation. You can create inline patches from your kustomization.yaml file such as below:

OpenShift

The Helm chart and Kubernetes manifests above are compatible with OpenShift, however you need to run with an additional environment variable: HOME=/home/atlantis. This is required because OpenShift runs Docker images with random user id's that use / as their home directory.

AWS Fargate

If you'd like to run Atlantis on AWS Fargateopen in new window check out the Atlantis module on the Terraform Module Registryopen in new window and then check out the Next Steps.

Google Kubernetes Engine (GKE)

You can run Atlantis on GKE using the Helm chart or the manifests.

There is also a set of full Terraform configurations that create a GKE Cluster, Cloud Storage Backend and TLS certs: https://github.com/sethvargo/atlantis-on-gkeopen in new window.

Once you're done, see Next Steps.

Google Compute Engine (GCE)

Atlantis can be run on Google Compute Engine using a Terraform module that deploys it as a Docker container on a managed Compute Engine instance.

This Terraform moduleopen in new window features the creation of a Cloud load balancer, a Container-Optimized OS-based VM, a persistent data disk, and a managed instance group.

After it is deployed, see Next Steps.

Docker

Atlantis has an officialopen in new window Docker image: ghcr.io/runatlantis/atlantis.

Customization

If you need to modify the Docker image that we provide, for instance to add the terragrunt binary, you can do something like this:

  1. Create a custom docker file

    FROM ghcr.io/runatlantis/atlantis:{latest version}
    
    # copy a terraform binary of the version you need
    COPY terragrunt /usr/local/bin/terragrunt
    
  2. Build your Docker image

    docker build -t {YOUR_DOCKER_ORG}/atlantis-custom .
    
  3. Run your image

    docker run {YOUR_DOCKER_ORG}/atlantis-custom server --gh-user=GITHUB_USERNAME --gh-token=GITHUB_TOKEN
    

Microsoft Azure

The standard Kubernetes Helm Chart should work fine on Azure Kubernetes Serviceopen in new window.

Another option is Azure Container Instancesopen in new window. See this community member's repoopen in new window or the new and more up-to-date Terraform moduleopen in new window for install scripts and more information on running Atlantis on ACI.

Note on ACI Deployment: Due to a bug in earlier Docker releases, Docker v23.0.0 or later is required for straightforward deployment. Alternatively, the Atlantis Docker image can be pushed to a private registry such as ACR and then used.

Roll Your Own

If you want to roll your own Atlantis installation, you can get the atlantis binary from https://github.com/runatlantis/atlantis/releasesopen in new window or use the official Docker imageopen in new window.

  • $USERNAME is the GitHub/GitLab/Bitbucket/AzureDevops username you generated the token for
  • $TOKEN is the access token you created. If you don't want this to be passed in as an argument for security reasons you can specify it in a config file (see Configuration) or as an environment variable: ATLANTIS_GH_TOKEN or ATLANTIS_GITLAB_TOKEN or ATLANTIS_BITBUCKET_TOKEN or ATLANTIS_AZUREDEVOPS_TOKEN
  • $SECRET is the random key you used for the webhook secret. If you don't want this to be passed in as an argument for security reasons you can specify it in a config file (see Configuration) or as an environment variable: ATLANTIS_GH_WEBHOOK_SECRET or ATLANTIS_GITLAB_WEBHOOK_SECRET
  • $REPO_ALLOWLIST is which repos Atlantis can run on, ex. github.com/runatlantis/* or github.enterprise.corp.com/*. See Repo Allowlist for more details.

Atlantis is now running!

TIP

We recommend running it under something like Systemd or Supervisord that will restart it in case of failure.

Next Steps

  • To ensure Atlantis is running, load its UI. By default Atlantis runs on port 4141.
  • Now you're ready to add Webhooks to your repos. See Configuring Webhooks.
