• @319 (@main319, @community319)
• @318 (@main318, @community318)

Utilities

All images contain the following extra packages:

• tini A tiny but valid init for containers.
• monit Managing and monitoring on a UNIX system.
• inotify-tools CLI tools providing a simple interface to inotify.
• dropbear Small SSH 2 client/server designed for small memory environments.
• envsubst Substitutes environment variables in shell format strings.
