azure - 检查 CI/CD 管道中 Kubernetes 部署是否成功

Question

我有一个 Kubernetes 版本为 1.14.7 的 AKS 集群。

我已经构建了 CI/CD 管道以将新创建​​的镜像部署到集群。

我正在使用 kubectl apply 使用新镜像更新特定部署。有时，由于多种原因，部署会失败，例如 ImagePullBackOff。

在 kubectl apply 命令之后是否需要运行命令来检查 Pod 创建和部署是否成功？

为此，Kubernetes 有 kubectl rollout，您应该使用选项 status。

By default 'rollout status' will watch the status of the latest rollout until it's done. If you don't want to wait for the rollout to finish then you can use --watch=false. Note that if a new rollout starts in-between, then 'rollout status' will continue watching the latest revision. If you want to pin to a specific revision and abort if it is rolled over by another revision, use --revision=N where N is the revision you need to watch for.

如果您使用kubect apply -f myapp.yaml并检查rollout status，您将看到:

$ kubectl rollout status deployment myapp
Waiting for deployment "myapp" rollout to finish: 0 of 3 updated replicas are available…
Waiting for deployment "myapp" rollout to finish: 1 of 3 updated replicas are available…
Waiting for deployment "myapp" rollout to finish: 2 of 3 updated replicas are available…
deployment "myapp" successfully rolled out
