So an hour later, while logged out (in incognito mode) I am seeing your post on https://slrpnk.net/c/[email protected] and can find it on your home instance directly at https://slrpnk.net/post/14701745 - this is in addition to seeing it on https://lemmy.ca/c/woodworking and directly on the magazine’s instance at https://lemmy.ca/post/31909201
Also, the post likewise shows up for me when I view your profile on either your home instance at https://slrpnk.net/u/technomad or on the magazine’s instance at https://lemmy.ca/u/[email protected] (and again, that’s logged out and in incognito mode).
Finally, I see your post on lemmy.world in the same three places - the magazine https://lemmy.world/c/[email protected] , your profile https://lemmy.world/u/[email protected] , and the direct post itself https://lemmy.world/post/21403325
Sometimes posts from lemmy.world take up to three days to federate to my instance, so an hour isn’t too bad really.
This is actually very easy. You can copy the files from the container, even while it’s not running, onto your host system to edit there, and then copy them back afterwards.
See the top answer on https://stackoverflow.com/questions/22907231/how-to-copy-files-from-host-to-docker-container for step by step instructions on how to do this.
