builderer

Container based mono repo builder

builderer builds docker based projects both in ci/cd and locally omitting endless configuration and the need to restart ci/cd pipelines to get a running build.

Features

Build steps – build, tag, push, pull and forward container images.
Custom steps – run arbitrary commands as build or post steps when the built-in steps aren't enough.
Parallel execution – run steps concurrently; num_parallel / max_parallel accept a number, cores, or all.
Step selection – give steps an id and choose what runs with --skip / --only.
docker & podman backends.
Editor support – a published JSON schema for .builderer.yml.
CI- & local-friendly – graceful Ctrl-C, --simulate, and --verbose output.

Help
