Highly recommended things!

This is my five-star list. These are my favorite things in all the world.

A few of these works have had an extraordinary effect on my life or way of thinking. They get a sixth star. ★

If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

1. Copy content of original credentials rails credentials:show somewhere temporarily.
2. Remove config/master.key and config/credentials.yml.enc
3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
5. Add and Commit the file config/credentials.yml.enc

This is how to automatically delete cached image previews from your Mastodon instance if they are older than 7 days.
Log in as your "mastodon" User or log in as root and then change to the "mastodon" user, who runs Mastodon:

  # su - mastodon

Open crontab:

  $ crontab -e
  
... and add these lines to your crontab:
