1. How to disable auth for 'default' user

To disable auth for 'default' user, you can unset the environment variable REDIS_DEFAULT_PASSWORD when creating the cluster.

# unset REDIS_DEFAULT_PASSWORD to disable auth for 'default' user
env:
  - name: REDIS_DEFAULT_PASSWORD

for instance, when creating a replication cluster without auth, you use the following yaml:

apiVersion: apps.kubeblocks.io/v1
kind: Cluster
metadata:
  name: redis-replication-without-auth
  namespace: demo
spec:
  terminationPolicy: Delete
  clusterDef: redis
  topology: replication
  componentSpecs:
    - name: redis
      env:
        - name: REDIS_DEFAULT_PASSWORD # unset this env var to disable auth for default user
          value: ""
      serviceVersion: "7.2.4"
      disableExporter: false
      replicas: 2
      resources:
        limits:
          cpu: '0.5'
          memory: 0.5Gi
        requests:
          cpu: '0.5'
          memory: 0.5Gi
      volumeClaimTemplates:
        - name: data
          spec:
            storageClassName: ""
            accessModes:
              - ReadWriteOnce
            resources:
              requests:
                storage: 20Gi
    - name: redis-sentinel
      replicas: 3
      serviceVersion: "7.2.4"
      resources:
        limits:
          cpu: '0.5'
          memory: 0.5Gi
        requests:
          cpu: '0.5'
          memory: 0.5Gi
      volumeClaimTemplates:
        - name: data
          spec:
            storageClassName: ""
            accessModes:
              - ReadWriteOnce
            resources:
              requests:
                storage: 20Gi

Similarly, you can disable auth for 'default' user when creating a sharding cluster:

apiVersion: apps.kubeblocks.io/v1
kind: Cluster
metadata:
  name: redis-sharding-without-auth
  namespace: demo
spec:
  terminationPolicy: Delete
  shardings:
  - name: shard
    shards: 3
    template:
      name: redis
      componentDef: redis-cluster-7
      replicas: 2
      env:
        - name: REDIS_DEFAULT_PASSWORD # unset this env var to disable auth for default user
          value: ""
      resources:
        limits:
          cpu: '1'
          memory: 1Gi
        requests:
          cpu: '1'
          memory: 1Gi
      serviceVersion: 7.2.4
      volumeClaimTemplates:
      - name: data
        spec:
          accessModes:
          - ReadWriteOnce
          resources:
            requests:
              storage: 20Gi
