documentation doesn't list what all the containers do

[SvenDowideit]

run.sh has docker-compose up -d core web certbot registry-mirror squid mirror smb

The Readme.md has:

• dnsmasq (provides DHCP and TFTP services)
• nginx
• squid - optional, used for caching http requests
• registry - optional, used for caching Docker images
• Gitea - optional, used for mirroring git repositories

considering that core is both privileged, and uses all the host namespaces, this deserves more exposition.

Good point. We will revise this on the next release.
