AWS CodeBuild Default Environment Variables

Question

I'm having an issue while logging into ECR.

buildspec.yml

...
- echo $AWS_DEFAULT_REGION and $AWS_ACCOUNT_ID
- aws ecr get-login-password --region $AWS_DEFAULT_REGION | docker login --username AWS --password-stdin $AWS_ACCOUNT_ID.dkr.ecr.$AWS_DEFAULT_REGION.amazonaws.com

Following command return me "us-east-2" and "" ($AWS_ACCOUNT_ID is empty)

- echo $AWS_DEFAULT_REGION and $AWS_ACCOUNT_ID

so that's why I'm unable to login to ECR.

Because there is no default codebuild environment variable named AWS_ACCOUNT_ID

Here Environment variables in build environments you can find all default codebuild environment variables.

Is there any work around to get the account ID?

samtoddler Over a year ago

@Yougesh you can instrument something with GetCallerIdentity API call.

In addition to @samtoddler, you can add this to your CloudFormation template, this will give you the output for $AWS_ACCOUNT_ID in the buildspec.yml

"EnvironmentVariables": [
                        {
                            "Name": "AWS_ACCOUNT_ID",
                            "Value": {
                                "Ref": "AWS::AccountId"
                            }
                        }
                    ],
