Hello All,
I currently have a home server on a raspberry pi 4 with all my services running as docker containers. All containers have their own directories containing the config and database files. This makes it easy to backup and export then.
However, in the future I have plans to migrate to a more powerful server. This means I will probably not be using a CPU with an ARM architecture. So effectively, I will also have to use the corresponding docker images. So will this new x86 docker image work with my backup docker config volumes?
You’ll have to make sure the volumes are mapped to appropriate directories. Such that if on your pi setup its
/somedir/app1/blah, that you change it to/newdir/app1/blah.It’s even easier if you re-create the same directory heirarchy on the new server, and you can rsync your folders over. I found it easier to re-create the containers first, and all my volume mounts are
bindtype: ie use an existing folder, rather than letting docker create the volume wherever it wants.I did exactly this kind of migration not that long ago, and for the same reason, and from the same source/destination platforms.
