      - REPOSITORY_URI=XXXXXXXXXX.dkr.ecr.us-east-1.amazonaws.com/devopswebbuild
      - COMMIT_HASH=$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)
      - IMAGE_TAG=${COMMIT_HASH:=latest}
  build:
    commands:
      - docker build -t $REPOSITORY_URI:latest .
      - docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:$IMAGE_TAG

Solution :

  1. From the AWS CodeBuild Console, select the Build Project.
  2. Select the 'Edit' dropdown from the top-right corner, and select the 'Environment' option.
  3. Within the 'Edit Environment' page, select 'Override image'. After this, scroll down to find the 'Privileged' option and select it.
  4. Select 'Update Environment' to ensure that the property is updated.
