Structure

env

variables

This section sets environment variables that will propagate to the container that performs the build:

env:
  variables:
    MY_VARIABLE: 'some value'

Note that if this build project is part of a CodePipeline pipeline, which is set up with a CloudFormation stack template, additional environment variables can be set at CodeBuild project/CloudFormation stack template level and passed to the build container, as shown here: CodePipeline-Driven CodeBuild Builds. The availability of such environment variable can be tested

artifacts

If this build is driven by CodePipeline, the artifacts declared here are placed, as S3 objects, into the CodePipeline Build action's Output Artifact, which is an S3 "folder". For more details about CodePipeline output artifacts, see:

CodePipeline Artifacts

Examples

Verifying that an Environment Variable is Set

      - if [ -z "${AWS_REGION}" ]; then echo "AWS_REGION variable not set" 1>&2; exit 1; fi
