Accessing AWS CodeBuild Variables in AWS CodePipeline
I am trying to use AWS CodeBuild ID as a tag for my docker image. This docker image is embedded in the build phase of CodeBuild. I want to get this Coudebuild ID which is my docker tag in the AWS Code Pipeline phase. How do I access these codebuild environment variables in aws codepeline?
CodeBuild Phase:
CodeBuildProject:
Type: AWS::CodeBuild::Project
Properties:
Artifacts:
Location: !Ref ArtifactBucket
Type: "S3"
Source:
Location: !Sub ${ArtifactBucket}/source.zip
Type: "S3"
BuildSpec: |
version: 0.1
phases:
pre_build:
commands:
- $(aws ecr get-login --region $AWS_DEFAULT_REGION)
- sudo apt-get update
- echo Pulling maven image...
- docker pull maven:3.3-jdk-8
- echo done with the pre build phase
build:
commands:
- echo Build started on `date`
- printf "%s" $REPOSITORY_URI
- docker run -i --rm -w /opt/maven -v $PWD:/opt/maven -v $HOME/.m2:/root/.m2 maven:3.3-jdk-8 mvn clean install
- docker build --file Dockerfile --tag $REPOSITORY_URI:$CODEBUILD_BUILD_ID .
post_build:
commands:
- echo post build
- docker push $REPOSITORY_URI:$CODEBUILD_BUILD_ID
discard-paths: yes
Environment:
ComputeType: "BUILD_GENERAL1_LARGE"
Image: "aws/codebuild/docker:1.12.1"
Type: "LINUX_CONTAINER"
EnvironmentVariables:
- Name: AWS_DEFAULT_REGION
Value: !Ref AWS::Region
- Name: REPOSITORY_URI
Value: !Sub ${AWS::AccountId}.dkr.ecr.${AWS::Region}.amazonaws.com/${Repository}
- Name: PipelineName
Value: !Ref PipelineName
Name: !Ref AWS::StackName
ServiceRole: !Ref CodeBuildServiceRole
Here, my docker image is now a combination of my repository url and my code. I want to use this codebuild id in aws codepipeline deployment phase, how to get it?

You can write a build.json file with tag information during the post_build phase of your code build
post_build:
commands:
- echo post build
- docker push $REPOSITORY_URI:$CODEBUILD_BUILD_ID
- printf '{"Tag":"%s"}' "$REPOSITORY_URI:$CODEBUILD_BUILD_ID" > /tmp/build.json
artifacts:
files: /tmp/build.json
discard-paths: yes
In your pipeline, you can now simply read your tag like this:
ParameterOverrides: !Sub |
{
"Tag" : { "Fn::GetParam" : [ "BuildOutput", "build.json", "Tag" ] },
.........
}
