These are dockerfiles maintained for third-party tools, languages, and the apextoaster/base utility image.
To make pipelines and updates easy, these are in a monorepo. Make sure images build to the same hash (clean up caches).
Clean up apt-get with apt-get autoclean && apt-get clean && rm -rf /var/lib/apt/lists/*.
/build and /secrets are reserved mount points for CI jobs.
/config and /data are reserved mount points for runtime data.
Tools that need an install directory should use /<tool>.
