DevOps Pipeline does not update pods

问题

I have a AKS infrastructure where I deploy my projects using DevOps pipeline.

Unfortunately my procedure is:

  1. Delete pods manually
  2. Run pipeline

There is no better way?

My pipeline is:

  1. trigger: none
  3. resources:
  4.   - repo: self
  5. pr:
  6.   - develop
  8. variables:
  9.   *
  11. stages:
  12.   - stage: Build
  13.     displayName: Build Stage
  14.     jobs:
  15.       - job: Build
  16.         displayName: Build
  17.         pool:
  18.           vmImage: $(vmImageName)
  19.         steps:
  20.           - task: MavenAuthenticate@0
  21.           - task: Maven@3
  22.           - task: Docker@2
  23.           - upload: manifests
  24.             artifact: manifests
  25.   - stage: Deploy
  26.     displayName: Deploy stage
  27.     jobs:
  28.       - deployment: Deploy
  29.         displayName: Deploy
  30.         workspace:
  31.           clean: all
  32.         pool: Default
  33.         environment: $(clusterEnv)
  34.         strategy:
  35.           runOnce:
  36.             deploy:
  37.               steps:
  38.                 - task: KubernetesManifest@0
  39.                   displayName: Deploy to kubernetes cluster
  40.                   inputs:
  41.                     action: deploy
  42.                     namespace: $(k8sNamespace)
  43.                     kubernetesServiceConnection: $(kubernetesServiceConnection)
  44.                     manifests: |
  45.                       $(Pipeline.Workspace)/manifests/myManifest.yml
  46.                     containers: $(containerRegistry)/$(imageRepo):latest

Do I have something wrong at deploy stage? or forgeting something?

你所经历的是使用最新标签的效果。

Kubernetes 没有检测到清单的变化，它不知道最新标签的镜像已更改...

如果它认为清单中的部署没有变化，那么容器将不会重新创建。

通常不建议使用 latest 标签，所以建议不再使用它... 这将解决你的问题。

英文:

What you're experiencing is the effect of using the latest tag.

Kubernetes doesn't see a change to the manifest, it doesn't know that the image with the latest tag has changed...

If it doesn't think the deployment from the manifest is different then the pods will not be recreated.

It's generally bad practice to use latest, so I'd suggest moving away from that... which in turn resolves your problem.
