In v3.12.33 a new feature has been added. You can now roll your secret key.

This is useful if you think your secret key has been compromised.

It is introduced because there was a security issue with the secret key. If you are using a version below v3.12.33, please update your Coolify instance.

Technical details: The secret key was generated with the installation date used as a random seed. This means that if someone knows the installation date, they can generate the secret key. This is not a problem if you are using a recent version of Coolify, because the installation date is not used anymore since 2023.07.14.

​
How to roll the secret key

If you are upgrading form a version below v3.12.33, you will be automatically rolled to a new secret key.

If you are just installing Coolify, you do not need to do anything.

​
Rollback to old secret key

(It also solve this issue related to secretOrPrivateKey must be an asymmetric key when using RS256 or Getting 500 error when accessing running services).

If you want to rollback to the old secret key, you need to do the followings:

  1. Login to your Coolify instance via SSH.
  2. Switch to root user (sudo su -) and locate your ~/coolify/.env file.
  3. In ~/coolify/.env file there should be a COOLIFY_SECRET_KEY environment variable.
  4. Create a COOLIFY_SECRET_KEY_BETTER with the same value as COOLIFY_SECRET_KEY.
  5. Check your database files with docker exec coolify ls -l /app/db command.
  6. There should be at least on with the name of prod.db and a few with prod.db_<date>.
  7. Locate the oldest one. For example:
-rw-r--r-- 1 root root 7901184 Aug 23 09:30 prod.db
-rw-r--r-- 1 root root 7901184 Jul 18 10:09 prod.db_1689674942980 <- THIS (date could be different)
  1. Make a copy of your prod.db file: docker exec coolify cp /app/db/prod.db /app/db/prod.db_$(date +"%Y%m%d%H%M%S")
  2. Overwrite prod.db with the old database file: docker exec coolify cp /app/db/prod.db_1689674942980 /app/db/prod.db

app/db/prod.db_1689674942980 will be different in your case

  1. Reinstall Coolify with: cd ~ && wget -q https://get.coollabs.io/coolify/install.sh -O install.sh; sudo bash ./install.sh -f
