stritzinger/rebar3_docker

This system is the rebar3\_docker plugin, an Erlang tool that automates the creation of Docker containers from Erlang releases. It functions by generating Dockerfiles from templates and executing builds, supporting configuration for image tags, ports, and environment variables. Recent updates have expanded its capabilities to include multi-platform build support and more flexible builder image customization. The system remains focused on streamlining the containerization workflow for Erlang applications within the rebar3 ecosystem.

This commit introduces the initial version (0.1.0) of the rebar3\_docker plugin, a tool for building Docker containers from Erlang releases. The plugin adds a \rebar3 docker build\ command that generates a Dockerfile using a Mustache template and executes the Docker build process. It supports configuration via the rebar config for Docker image tags, Erlang base image versions, exposed ports, environment variables, and build/runtime packages, and includes logic to pass SSH agent sockets for private repository access during the build.

Users can now specify multiple Docker platforms for builds via the new 'platform' configuration option, which passes the corresponding --platform flag to the Docker CLI. The default Erlang version for the builder image has been updated to 25.3.2.2, and the system now automatically derives the builder image from the Erlang version if a custom 'builder\_image' is not explicitly provided. Additionally, the Docker build profile selection logic has been corrected to pick the last profile in the list rather than the first.
