Seing issues connecting to redis on IPv6 only cluster

[dioguerra]

The bug

immich connecting to redis on IPv6 only cluster fails.

Can create a debug container and connect without problems:

kn media-server debug -it --image=nicolaka/netshoot immich-7b7d4bdb4b-8plsx

host media-server-redis-master.media-server.svc.cluster.local
media-server-redis-master.media-server.svc.cluster.local has IPv6 address fd00:10:96::667c

AND ======

kn media-server debug -it --image=ubuntu immich-7b7d4bdb4b-8plsx

apt update && apt install redis

kn media-server debug -it --image=ubuntu immich-7b7d4bdb4b-8plsx

redis-cli -h media-server-redis-master.media-server.svc
media-server-redis-master.media-server.svc:6379> KEYS *
(empty array)

Although I saw on docs that IPv6 is supported, and some Issues from other users point to problems of redis configuration, i think this is from immich container specifically to the redis module? PostgreSQL seems to resolve to the server without problems...

This is the failure from immich container:

I believe the solution is outlined in #10397

[dioguerra]

Thank you for pointing out to that page.

For all fellows searching for this issue, and because there is lot's of pointers but nobody presents anything. For a single client configuration it should be something like:

echo '{"host": "media-server-redis-master.media-server.svc.cluster.local", "db": 0, "family": 6}' | base64 -w0

add fields:

username
password

if configured

Then set:

REDIS_URL: ioredis://<base64>
