如何更新kubernetes部署映像和命令？ [英] How do I update kubernetes deployment image and command?

问题描述

我看到我可以使用 kubectl set image命令来更新部署中使用的容器，例如：

I see that I can use the "kubectl set image" command to update a container used in a deployment, like this:

kubectl set image deployment/myapp myapp=repo.mycompany.com/myapp/ui:beta.119

但是，我还想在某些情况下使用其他启动命令。有没有办法同时更新图像和用于容器的命令？

But, i would also like to use a different startup command in some situations. Is there a way to update both the image AND the command used for the container?

推荐答案

您可以使用 kubectl补丁。运行 kubectl patch --help 来获取文档，但据我所知，应该这样做：

You could use kubectl patch for that. Run kubectl patch --help to get the docs, but as far as I can tell something like this should do it:

$ kubectl patch deployment <your-deployment> -p '
spec:
  template:
    spec:
      containers:
        - name: <container-name>
          command: ["new", "command"]
'
