根据需求搭建一个不需要数据持久化,需要密码登录的 Redis

mkdir /iba/qa_ibaboss_elk -p

cd /iba/qa_ibaboss_elk

# 创建一个专用的 namespace
cat namespace.yaml 
---

apiVersion: v1
kind: Namespace
metadata:
  name: qa-ibaboss-elk

kubectl apply -f namespace.yaml 

# 查看 namespace
kubectl get namespace

创建一个 configmap

mkdir config && cd config

cat redis.conf

# 在 qa-ibaboss-elk namespace 中创建 configmap
kubectl create configmap qa-ibaboss-elk-redis-conf --from-file=redis.conf -n qa-ibaboss-elk

创建 redis 容器

cat qa_ibaboss_elk_redis.yaml 
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: qa-ibaboss-elk-redis
  namespace: qa-ibaboss-elk
spec:
  replicas: 1
  template:
    metadata:
     labels:
       name: qa-ibaboss-elk-redis
    spec:
     containers:
     - name: qa-ibaboss-elk-redis
       image: redis
       volumeMounts:
       - name: foo
         mountPath: "/usr/local/etc"
       command:
         - "redis-server"
       args:
         - "/usr/local/etc/redis/redis.conf"
     volumes:
     - name: foo
       configMap:
         name: qa-ibaboss-elk-redis-conf
         items:
           - key: redis.conf
             path: redis/redis.conf

# 创建和查看 pod
kubectl apply -f qa_ibaboss_elk_redis.yaml 
kubectl get pods -n qa-ibaboss-elk

# 注意:configMap 会挂在 /usr/local/etc/redis/redis.conf 上。与 mountPath 和 configMap 下的 path 一同指定

可以创建一个 busybox 容器进去测试

kubectl run busybox --image=busybox -n qa-ibaboss-elk --command -- ping baidu.com
