Mat's Docker Image collection

Various Docker files that I use.

NOTE: You'll need TCL installed on your system. I use my own copy of tangle based on literate programming. If you want to use a docker file, you'll have to generate it.

Standard Docker Stuff

I like to insure that my containers follow a few simple rules.

• Never run as root.

  • For containers, I liked to have a single user I run in.
  • Needed software and configuration that requires root should be done first.
  • At the end, the container should default to be running as that user.

• A set working directory that can be a docker volume or a volume passed from the host.

  • This present a challenge in make sure that that uid/gid is correct between the active user and the directory.
  • When using a host volume, I also have to make sure the UID/GID matches to not have any permission issues.

• While we also like to use the latest version of a base docker image, that isn't always possible.

  • We should default to building the latest version, but allow for changing that.

Docker Files

• ubi9+epel
  • Redhat's Universal Base Image (UBI) for RHEL9, with epel installed and read for use.
• ubuntu
  • Yes, I use Ubuntu from time to time.
• fossil
  • I use fossil quite a bit. Nice to have an easy way to run it. I would recommend use the Dockerfile provide by fossil. I have this one here to highlight the usage of the scratch docker image.

As always, go Guardians!
