Looks great at a glance. I admittedly got pretty frustrated and gave up doing the straight docker install primarily with the nginx portion of my setup. The lemmy instructions were lacking. After trying for 2 days I just used the recommended Ansible playbook and it worked beautifully and now I've gone back and reconfigured what I wanted to after the fact.
So this is biggly helpful. Thanks! Im gonna give it a thorough looking at next time I fiddle with my config. Got it saved.
