Redis 설치

로컬 개발 목적이므로 standalone으로 설치한다.

$ kubectl create namespace redis
$ helm install redis -f values.yaml . -n redis

NAME: redis
LAST DEPLOYED: Sat May 27 14:06:38 2023
NAMESPACE: redis
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: redis
CHART VERSION: 17.10.3
APP VERSION: 7.0.11

** Please be patient while the chart is being deployed **

Redis® can be accessed on the following DNS names from within your cluster:

    redis-master.redis.svc.cluster.local for read/write operations (port 6379)
    redis-replicas.redis.svc.cluster.local for read-only operations (port 6379)



To get your password run:

    export REDIS_PASSWORD=$(kubectl get secret --namespace redis redis -o jsonpath="{.data.redis-password}" | base64 -d)

To connect to your Redis® server:

1. Run a Redis® pod that you can use as a client:

   kubectl run --namespace redis redis-client --restart='Never'  --env REDIS_PASSWORD=$REDIS_PASSWORD  --image docker.io/bitnami/redis:7.0.11-debian-11-r7 --command -- sleep infinity

   Use the following command to attach to the pod:

   kubectl exec --tty -i redis-client \
   --namespace redis -- bash

2. Connect using the Redis® CLI:
   REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h redis-master
   REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h redis-replicas

To connect to your database from outside the cluster execute the following commands:

    export NODE_IP=$(kubectl get nodes --namespace redis -o jsonpath="{.items[0].status.addresses[0].address}")
    export NODE_PORT=$(kubectl get --namespace redis -o jsonpath="{.spec.ports[0].nodePort}" services redis-master)
    REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h $NODE_IP -p $NODE_PORT

paasword

$ export REDIS_PASSWORD=$(kubectl get secret --namespace redis redis -o jsonpath="{.data.redis-password}" | base64 -d)
$ echo $REDIS_PASSWORD

Redis 삭제

아래 명령어 외, Harbor 관련 PVC를 모두 삭제해야 재설치시 로그인 이슈가 없음

$ helm delete -n redis redis
