Pathfinder – Using The Existing Redis

Pathfinder comes in 4 docker images

  1. Pathfinder
  2. Pathfinder Websocket
  3. Mariadb
  4. Redis

If you are running SeAT 5.0, Mariadb and Redis are already installed. Can we use the existing services? Yes.

Redis – Accepting The External Connection

The default installation is probably only bound to the localhost (127.0.0.1). You need to bind it to a host IP. you will find /etc/redis/redis.conf.

bind 127.0.0.1 -::1 192.168.100.100

You need to adjust the private network address to your environment, but this will bind your redis server to a host ip address.

Reconfig docker-compose.yml

Then, you remove all redis part from docker-compose.yml

Again, I have removed traefik to use apache. See the previous posts for that.

You also need to edit .env to change

REDIS_HOST="192.168.100.100"

Then, rebuild the docker image and run using

$> docker compose up -d

Final Thoughts

Do I do this in the production environment. No.

  1. To ensure comptibility, I would use the one come with pathfinder.
  2. To reduce the security risk, I wouldn’t bind redis other than local host.

If we follow similar steps, we can connect to the existing database, but I haven’t succeeded yet. PHP 7.2 Pathfinder docker image is using doesn’t support MySQL caching_sha2_password. It’s about how much security risk you want to take.
