Podman Maven Plugin

A maven plugin to build, tag and push OCI compliant images configured using a Dockerfile/Containerfile using Podman.

About

This plugin was created based on the need to build container images with Podman, whilst not having an appropriate plugin to do so. Initially using the docker-maven-plugin from fabric8io it quickly became clear that simply swapping Docker for Podman (alias docker=podman) did not work as the plugin requires a Docker outlet to communicate with. With other plugins currently not yet available, the idea was born.

This plugin uses a ProcessExecutor from ZeroTurnaround to do its magic under water. Although this plugins' structure is similar to that from the docker-maven-plugin, its implementation is not. In an effort to keep things simple, I have chosen to use a ProcessExecutor to run podman rather than implementing the logic myself.

Also, only a subset of the podmans capabilities have been implemented (build, push and save).

This plugin is mainly inspired by the docker-maven-plugin and shows some similarities in configuration.
