feat: support running on a read-only filesystem

Open paulswartz opened this issue 3 years ago • 2 comments

Docker containers can run on a read-only filesystem, which has some security benefits. The current updater implementation writes the .tgz file to the filesystem, so it does not work in such an environment.

This provides a read_only_fs? configuration which stores the data in memory while loading, and does not write the ETS table to disk for future loading.

Rebased on top of the latest master, and remove the other implementation of the GitHub CI.
