I’ve greatly modified the official Docker Docs for installing on any currently supported SLES/SLED/openSUSE, likely running on any hardware architecture (One of these days I’ll get my hands on an openSUSE running on ARM to verify)…
Thx for the kudos, the basics are always a good place to start.
Since those were created,
Possibly the most significant newer developments (not necessarily invalidating anything in those tutorials) are the Composer tool and support for netowrking using bridge devices, which means that containers networking can be set up with a networking architecture similar to most hypervisor virtualization.
