k8s使用YAML创建redis5.0-创新互联

yaml部署redis的一个巨坑配置文件里面的daemonize no一定不能用daemonize yes，因为这个问题我搞了一个星期，

yaml文件的标签是关联各个服务的重要说明
labels  下面的name参数和后面的值各服务之间要全部一致才能正确关联,
metadata:
name: redis-yx-t-config
labels:
  name: gem-yx-t-redis

apiVersion: v1 
kind: ConfigMap 
metadata: 
  name: gem-yx-t-redis
  labels: 
    app: gem-yx-t-redis 
data: 
  redis.conf: |- 
    dir /data 
    port 6379 
    bind 0.0.0.0 
    appendonly yes 
    daemonize no       #这个是重点，不能yes，否则永远无法启动
    #protected-mode no 
    requirepass test
