Use this to create a cross account AWS Codepipeline which runs in a dedicated account and deploys artifacts in other accounts
- Source - github
- Buid - AWS CodeBuild
- Deploy - AWS Codepipeline ECS deployment
This is a simplified view of the solution detailing out all the components in use.
The various pipeline stages can be visualized as -
To create the ECS clusters in the respective accounts, you can use the ecs templates. To setup the cross account codepipeline, follow these steps -
First up, execute the base template codepipeline-base.yaml to setup the Codepipeline S3 artifact bucket, ECR repo and the KMS Key in the tools account (In the account where the pipeline will reside). Note down the ARN this template outputs, we will need it next.
aws cloudformation validate-template --template-body file:https://codepipeline-base.yaml \
--profile aws-tools-account
aws cloudformation create-stack --stack-name codepipeline-base-stack \
--template-body file:https://codepipeline-base.yaml \
--profile aws-tools-account --capabilities CAPABILITY_IAM
Next, execute the codepipeline-access.yaml in ALL the accounts you want the codepipeline to deploy to. For example, you might run this in dev, qa and prod accounts where your ECS clusters are. This template needs the KMS Key ARN as input from step 1.
aws cloudformation validate-template --template-body file:https://codepipeline-access.yaml \
--profile aws-dev-account
aws cloudformation create-stack --stack-name codepipeline-access-stack \
--template-body file:https://codepipeline-access.yaml \
--parameters ParameterKey=KMSKeyArn,ParameterValue="KMS_KEY_ARN" \
--profile aws-dev-account --capabilities CAPABILITY_NAMED_IAM
aws cloudformation create-stack --stack-name codepipeline-access-stack \
--template-body file:https://codepipeline-access.yaml \
--parameters ParameterKey=KMSKeyArn,ParameterValue="KMS_KEY_ARN" \
--profile aws-qa-account --capabilities CAPABILITY_NAMED_IAM
aws cloudformation create-stack --stack-name codepipeline-access-stack \
--template-body file:https://codepipeline-access.yaml \
--parameters ParameterKey=KMSKeyArn,ParameterValue="KMS_KEY_ARN" \
--profile aws-prod-account --capabilities CAPABILITY_NAMED_IAM
Finally, execute the codepipeline-stack.yaml in the tools AWS account to setup the codepipeline, codebuild project, IAM roles (for codepipeline, codebuild), SNS Topics (for approve/notify emails), cloudwatch event rules (for notifying on pipeline and buildproject state change).
aws cloudformation validate-template --template-body file:https://codepipeline-stack.yaml \
--profile aws-tools-account
aws cloudformation create-stack --stack-name codepipeline-stack \
--template-body file:https://codepipeline-stack.yaml \
--profile aws-tools-account --capabilities CAPABILITY_IAM
Drop me a note or open an issue if something doesn't work out.
