Approaching Docker, Containers, and Compose for curious Self-hosters

This is a bonus Linux Prepper podcast, available as a detailed companion to “A Great Year for Linux”. This is a discussion with HB, stemming from this post on Lemmy learning from admins who avoid container technology. We discuss our experiences with containers, who they are for, and the contexts in which we find them useful. If you are self-hosting, and are container curious, this one is for you!
