How to config Redis?

[gavinliu6]

I deployed Redis with Dokploy and want to change some configurations(such as maxmemory-policy configuration), but I can’t find redis.conf. How should I do this?

Ran into this too. In my testing, passing a custom args array via the redis.update API replaces the auto-generated startup command entirely — it does not merge with or re-inject --requirepass from the stored password field.

After setting args: ["--maxmemory", "576mb", "--maxmemory-policy", "allkeys-lru"] (no --requirepass), I confirmed via docker exec <container> redis-cli PING that the deployed container accepted unauthenticated connections, even though the "Internal Credentials" panel in the UI still showed a password.

Fix: include --requirepass <your-password> explicitly in the args array alongside whatever config flags you want:

{"redisId": "...", "args": ["--requirepass", "<password>", "--maxmemory", "576mb", "--maxmemory-policy", "allkeys-lru"]}

Verified after redeploy: docker inspect <container> --format "{{json .Config.Cmd}}" shows all three flags together, unauthenticated PING correctly returns NOAUTH Authentication required, and CONFIG GET maxmemory / maxmemory-policy reflect the values.

Worth flagging as a docs gap (or arguably a bug — args should probably append to the default command rather than replace it) since this silently drops auth with no warning in the UI, logs, or API response.
