ninech/deploio-heroku Base Images

This is a ninech fork of heroku/base-images, adapted for use with deplo.io. The recipes are rendered into Docker images available on the GitHub Container Registry:

Image	Type	OS	Supported Architectures	Default USER	Status
ghcr.io/ninech/deploio-heroku:24	Run Image	Ubuntu 24.04	AMD64 + ARM64	deploio	Recommended
ghcr.io/ninech/deploio-heroku:24-build	Build Image	Ubuntu 24.04	AMD64 + ARM64	deploio	Recommended

The build image variants use the run images as their base, but include additional packages needed at build time such as development headers and compilation toolchains.

For images where the default USER is deploio, you will need to switch back to the root user when modifying locations other than /home/deploio and /tmp. You can do this by adding USER root to your Dockerfile when building images, or by passing --user root to any docker run invocations.
