# Atlantis on AWS Fargate Terraform Module



[![SWUbanner](https://raw.githubusercontent.com/vshymanskyy/StandWithUkraine/main/banner2-direct.svg)](https://github.com/vshymanskyy/StandWithUkraine/blob/main/docs/README.md)



[Atlantis](https://www.runatlantis.io/) is tool which provides unified workflow for collaborating on Terraform through GitHub, GitLab and Bitbucket Cloud.



> Before using Atlantis and the code in this repository, please make sure that you have read and understood the security implications described in [the official Atlantis documentation](https://www.runatlantis.io/docs/security.html).



## Usage



GitHub is shown below in usage examples; however, any git provider supported by Atlantis can be used by simply using the correct Atlantis environment variables and configuring the respective webhook for the given git provider.



See the [Supplemental Docs](https://github.com/terraform-aws-modules/terraform-aws-atlantis/blob/master/docs/README.md) for additional details on integrating with git providers.



### GitHub Complete



The Atlantis module creates all resources required to run Atlantis on AWS Fargate.



```hcl

module "atlantis" {

  source  = "terraform-aws-modules/atlantis/aws"



  name = "atlantis"



  # ECS Container Definition

  atlantis = {

    environment = [

      {

        name  = "ATLANTIS_GH_USER"

        value = "myuser"

      },

      {

        name  = "ATLANTIS_REPO_ALLOWLIST"

        value = "github.com/terraform-aws-modules/*"

      },

    ]

    secrets = [

      {

        name      = "ATLANTIS_GH_TOKEN"

        valueFrom = "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes256-7g8H9i"

      },

      {

        name      = "ATLANTIS_GH_WEBHOOK_SECRET"

        valueFrom = "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes192-4D5e6F"

      },

    ]

  }



  # ECS Service

  service = {

    task_exec_secret_arns = [

      "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes256-7g8H9i",

      "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes192-4D5e6F",

    ]

    # Provide Atlantis permission necessary to create/destroy resources

    tasks_iam_role_policies = {

      AdministratorAccess = "arn:aws:iam::aws:policy/AdministratorAccess"

    }

  }

  service_subnets = ["subnet-xyzde987", "subnet-slkjf456", "subnet-qeiru789"]

  vpc_id          = "vpc-1234556abcdef"



  # ALB

  alb_subnets             = ["subnet-abcde012", "subnet-bcde012a", "subnet-fghi345a"]

  certificate_domain_name = "example.com"

  route53_zone_id         = "Z2ES7B9AZ6SHAE"



  tags = {

    Environment = "dev"

    Terraform   = "true"

  }

}

```



### GitHub Separate



The Atlantis module creates most of resources required to run Atlantis on AWS Fargate, except for the ECS Cluster and ALB. This allows you to integrate Atlantis with your existing AWS infrastructure.



```hcl

module "atlantis" {

  source  = "terraform-aws-modules/atlantis/aws"



  name = "atlantis"



  # Existing cluster

  create_cluster = false

  cluster_arn    = "arn:aws:ecs:eu-west-1:123456789012:cluster/default"



  # Existing ALB

  create_alb            = false

  alb_target_group_arn  = "arn:aws:elasticloadbalancing:eu-west-1:1234567890:targetgroup/bluegreentarget1/209a844cd01825a4"

  alb_security_group_id = "sg-12345678"



  # ECS Container Definition

  atlantis = {

    environment = [

      {

        name  = "ATLANTIS_GH_USER"

        value = "myuser"

      },

      {

        name  = "ATLANTIS_REPO_ALLOWLIST"

        value = "github.com/terraform-aws-modules/*"

      },

    ]

    secrets = [

      {

        name      = "ATLANTIS_GH_TOKEN"

        valueFrom = "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes256-7g8H9i"

      },

      {

        name      = "ATLANTIS_GH_WEBHOOK_SECRET"

        valueFrom = "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes192-4D5e6F"

      },

    ]

  }



  # ECS Service

  service = {

    task_exec_secret_arns = [

      "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes256-7g8H9i",

      "arn:aws:secretsmanager:eu-west-1:111122223333:secret:aes192-4D5e6F",

    ]

    # Provide Atlantis permission necessary to create/destroy resources

    tasks_iam_role_policies = {

      AdministratorAccess = "arn:aws:iam::aws:policy/AdministratorAccess"

    }

  }

  service_subnets = ["subnet-xyzde987", "subnet-slkjf456", "subnet-qeiru789"]

  vpc_id          = "vpc-1234556abcdef"



  tags = {

    Environment = "dev"

    Terraform   = "true"

  }

}

```



### Utilize EFS for Persistent Storage



You can enable EFS to ensure that any plan outputs are persisted to EFS in the event that the Atlantis Task is replaced:



```hcl

```hcl

module "atlantis" {

  source  = "terraform-aws-modules/atlantis/aws"



  # Truncated for brevity ...



  # EFS

  enable_efs = true

  efs = {

    mount_targets = {

      "eu-west-1a" = {

        subnet_id = "subnet-xyzde987"

      }

      "eu-west-1b" = {

        subnet_id = "subnet-slkjf456"

      }

      "eu-west-1c" = {

        subnet_id = "subnet-qeiru789"

      }

    }

  }

}

```



### Supply Atlantis server configuration



`server-atlantis.yaml`



```yaml

repos:

  - id: /.*/

    allow_custom_workflows: true

    allowed_overrides:

      - apply_requirements

      - workflow

    apply_requirements:

      - approved

    workflow: default

```



`main.tf`



```hcl

module "atlantis" {

  source  = "terraform-aws-modules/atlantis/aws"



  # ...



  atlantis = {

    environment = [

      {

        name : "ATLANTIS_REPO_CONFIG_JSON",

        value : jsonencode(yamldecode(file("${path.module}/server-atlantis.yaml"))),

      },

    ]

  }

}

```
