nuntz/checkbuild repository overview

⁠checkbuild

This image compares the timestamps of the latest builds for two Docker Hub images (assuming one of them is the the image the other one is based on -- aka base image), and executes an HTTP post to trigger a new build if the base image is more recent.

I created this image because the Docker Hub repository links build option only works for non-official images.

⁠Usage

docker run --env-file=.env checkbuild

This can easily be configured to run as cron job on the host.

⁠Environment Variables

Define these in your .env file:

• BASE_USERNAME: username of the upstream image repository
• BASE_REPOSITORY: name of the upstream image repository
• MY_USERNAME: your username
• MY_REPOSITORY: your repository
• BUILD_TRIGGER_URL: trigger build URL
• SLACK_WEBHOOK: Slack webhook for notifications
