Redis connection refused

Install / Update Setup
1

I’m trying running erpnext on docker but I’m having issues with redis cache which cannot be accessed apparently. The point is that I can ping the same servers claimed to be inaccessible from within the containers and they clearly see each other.

I provide a quick asciicast of what’s happening. Sorry but cannot attach json files. Just download and run asciinema play asciicast-99657.json

Hope somebody can help :blush:

Ya, this makes the whole front-end unusable, as the redis server keeps crashing and corrupting rdb file :sweat:

Additionally you can check the asciicast here as well:

All three redis instances running ps aux | grep redis and yet connection is reufsed:

redis 1 0.1 0.2 35356 4596 ? Ssl 20:28 0:00 redis-server *:6379

In response to bench update:

Damn :rage: Exposing ports inside Dockerfile, for some reason is not enough. You gotta tell again in your docker-compose file :dizzy_face:

Ports are not automatically exposed when running inside Docker, but rather explicitely by specifying -p / -P.

Fine, no big deal once you figure it out :sweat_smile:
