This was written at the time I was closing loops at the end of my time with the W3C. The intent at the time (before WebPlatform project closed was to host discuss.webplatform.org what is now known as W3C’s Web Platform Incubator Community Group (WICG) and is available as discourse.wicg.io
Recover Discourse from a backup, adjust domain name
procedure operations docker webplatform - 📁 experiments
Side by side comparison while working on migrating Discourse with WICG
Roughly based on Move your Discourse instance to a different server post. But without using the web UI. Because sysadmins prefers terminal.
IMPORTANT: Make SURE the backup dump was generated from the same Discourse version the one you'll import it into.
Copy from host backup into shared folder. Imagine you uploaded via SSH in your host home directory.
cp ~/snapshot.tar.gz /srv/webplatform/shared/backups/
Note that the folder /srv/webplatform/discuss/shared/standalone/backups/ from
the docker host would end up to be in /shared/backups/ inside the container.
Enter the VM, make sure enable_restore is run from discourse cli utility
./launcher enter app
discourse enable_restore
Find the mounted backup file from within the container
ll /shared/backups/default/
Make sure /shared/backups/foo.tar.gz is readable by can read
chmod o+r /shared/backups/default/foo.tar.gz
discourse restore foo.tar.gz
discourse disable_restore
Remap domain name
discourse remap discourse.specifiction.org discuss.webplatform.org
Then, work on user uploads and regenerate assets. That'll make sure ;
rake uploads:clean_up
rake posts:rebake
