Pass AWS CodePipeline variable to actions - amazon-web-services

Question

I'm trying to pass the CodePipeline variable #{codepipeline PipelineExecutionId} to both the codeBuild action and then a deploy action.
I understand this variable is readily available to all actions as explained in AWS docs.
I'm however having a difficulty with the syntax as the parameters is not passed thru into the actions.
I've been using the following code:
For the build actions:
- Name: "Build-Docker-Container"
Actions:
- Name: "Build-Docker-Container"
ActionTypeId:
Category: Build
Owner: AWS
Provider: CodeBuild
Version: "1"
Configuration:
ProjectName: !Sub ${ProjectName}-build-${BranchName}
EnvironmentVariables:
- Name: IMAGE_TAG
Type: PLAINTEXT
Value: "#{codepipeline.PipelineExecutionId}"
InputArtifacts:
- Name: !Ref ProjectName
RunOrder: 3
and for the deploy action:
- Name: "Deploy-Services"
Actions:
- Name: "Deploy-Services"
ActionTypeId:
Category: Deploy
Owner: AWS
Provider: CloudFormation
Version: "1"
Configuration:
ActionMode: CREATE_UPDATE
StackName: !Sub "${ProjectName}-services-${BranchName}"
TemplatePath: !Sub "${ProjectName}::aws/03-services.yml"
Capabilities: "CAPABILITY_NAMED_IAM"
RoleArn: !GetAtt DeployRole.Arn
ParameterOverrides: !Sub |
{
"ProjectName": "${ProjectName}",
"ExecutionId": "#{codepipeline.PipelineExecutionId}"
}
InputArtifacts:
- Name: !Ref ProjectName
- Name: InfrastructureOutput
RunOrder: 4
UPDATE The code was actually good; I just needed to update the CloudFormation pipeline stack to apply it (I thought the github webhook would trigger this, but it only update the actions inside the pipeline)

Answer 1

I can confirm that the syntax you've used in the deploy action is correct:
ParameterOverrides: !Sub |
{
"ProjectName": "${ProjectName}",
"ExecutionId": "#{codepipeline.PipelineExecutionId}"
}
I verified that on my Pipeline with CloudFormation provider. I can also confirm that this works as expected.
You can check in console if you edit the CFN action's in question, that the parameters are correctly set:
For now I can't verify build action, but by the look of it, it also seems fine.
