How to upgrade from redis-stack 7 to redis 8

[alexander-schranz]

I found no upgrade guide what change from 7 to 8. I'm currently using redis-stack which I think will now be replaced with redis so what I tried todo in my docker compose files:

ℹ️ THIS is the updated version which should work for other stumble over the same problem:

services:
   redis:
-    image: redis/redis-stack:7.4.0-v1
+    image: redis:8
     ports:
       - 6379:6379 # redis server
-      - 8001:8001 # redis insight
-    environment:
-      REDIS_ARGS: --requirepass supersecure
+    command: >
+      --requirepass supersecure
     volumes:
       - redisearch-data:/data

+  redisinsight: # optional for visualizing redis data
+    image: redis/redisinsight:latest
+    ports:
+      - 5540:5540 # redis insight: to connect use "redis://default:supersecure@redis:6379"
+    volumes:
+      - redisinsight-data:/data

volumes:
  redisearch-data:

The first part seems insight port does not work as insight isn't bundles with redis is that correct?

The more important issue is that REDIS_ARGS: --requirepass supersecure not longer works. I get:

AUTH failed: ERR AUTH called without any password configured for the default user. Are you sure your configuration is correct?

please ref to https://github.com/redis/redis/releases/tag/8.0.0

Redis 8.0 deprecates previous Redis and Redis Stack versions.

Stand alone RediSearch, RedisJSON, RedisTimeSeries, and RedisBloom are no longer needed as they are now part of Redis.

[sundb]

Redis-stack and Redis are two images, REDIS_ARGS should be a configuration of Redis-Stack, not of Redis.

I see I found a workaround:

-    environment:
-      REDIS_ARGS: --requirepass supersecure # NOT WORKING in Redis 8?
+    command: >
+      --requirepass supersecure

One open part if I have redisinsight as an own container how let it connect to redis itself (not a docker expert):

My new docker compose is:

services:
  redis:
    image: redis:8
    ports:
      - 6379:6379
    command: >
      --requirepass supersecure
    volumes:
     - redisearch-data:/data

  redisinsight: # optional for visualizing redis data
    image: redis/redisinsight:latest
    ports:
      - 5540:5540
    depends_on:
      - "redis"

volumes:
  redisearch-data:

fixed it need to use now redis://default:supersecure@redis:6379 instead of redis://default:supersecure@127.0.0.1:6379
