Mainly rootless podman containers for different services.
If there is instuctions or link to instructions, they are under service specific folder in README.md file.
If you don't know nothing about Linux, podman, cli etc. Don't try these at home.
Almost every compose.yaml and Containerfile needs to be modified users own needs.
These containers are ment to use as service specific user (e.g. virtlyst runs under user virtlyst)
