dapr sidecar 容器无法启动

今天在 kubernetes 集群上部署应用时出现 dapr sidecar 容器因为健康检查失败而无法启动的问题

Container daprd failed liveness probe, will be restarted
Liveness probe failed: Get "http://192.168.15.143:3501/v1.0/healthz": dial tcp 192.168.15.143:3501: connect: connection refused
Readiness probe failed: Get "http://192.168.15.143:3501/v1.0/healthz": dial tcp 192.168.15.143:3501: connect: connection refused

问题补充：

通过查看 dapr-sentry 的日志发现，原来是 dapr 的根证书过期了

kubectl logs deploy dapr-sentry -n dapr-system

日志内容

level=warning msg="Dapr root certificate expiration warning: certificate has expired."
