In the thread Docker - change default ip range for all and new containers - #14 by dustin781, I mentioned that I’m reinstalling.
I had already redone everything with Nginx. Now I’ve moved from Ubuntu to Debian.
Using mc, I copied both folders via SFTP to /tmp/nginxbackup, but directly into the compose in Portainer didn’t work. Then, I copied both folders from the backup folder into the compose folder. Boom, it worked.
Very awesome!
