Liveness 和 Readiness 的三种使用方式

     readinessProbe:  # 定义只有http检测容器6379端口请求返回是 200-400,则接收下面的Service web-svc 的请求
httpGet:
scheme: HTTP
path: /check
port: 6379
initialDelaySeconds: 10 # 容器启动 10 秒之后开始探测,注意观察下g1的启动成功时间
periodSeconds: 5 # 每隔 5 秒再探测一次
timeoutSeconds: 5 # http检测请求的超时时间
successThreshold: 1 # 检测到有1次成功则认为服务是`就绪`
failureThreshold: 3 # 检测到有3次失败则认为服务是`未就绪`
livenessProbe: # 定义只有http检测容器6222端口请求返回是 200-400,否则就重启pod
httpGet:
scheme: HTTP
path: /check
port: 6379
initialDelaySeconds: 10
periodSeconds: 5
timeoutSeconds: 5
successThreshold: 1
failureThreshold: 3

#-----------------------------------------

readinessProbe:
exec:
command:
- sh
- -c
- "redis-cli ping"
initialDelaySeconds: 5
periodSeconds: 10
timeoutSeconds: 1
successThreshold: 1
failureThreshold: 3
livenessProbe:
exec:
command:
- sh
- -c
- "redis-cli ping"
initialDelaySeconds: 30
periodSeconds: 10
timeoutSeconds: 5
successThreshold: 1
failureThreshold: 3

#-----------------------------------------

readinessProbe:
tcpSocket:
port: 9092
initialDelaySeconds: 15
periodSeconds: 10
livenessProbe:
tcpSocket:
port: 9092
initialDelaySeconds: 15
periodSeconds: 10
