Jib Custom Entrypoint Extension

A general-purpose extension that enables to customize an image's entrypoint by adding prefix/suffix to the original entrypoint or override it completely.

How it works

Extensions allow one to customize Google Jib Docker image entrypoint by adding specific prefixes/suffixes to the original one and therefore to avoid overriding classpath and main-class.

Example:

Default entrypoint: java -cp /app/resources:/app/classes:/app/libs/* Application after adding prefix ./wait-for-it.sh google.com:80 -- becomes ./wait-for-it.sh google.com:80 -- java -cp /app/resources:/app/classes:/app/libs/* Application which makes health-check requests before running the application.
