英文:
List deployments using apimachinery by the .spec.selector.matchLabels key
问题
我想根据在.spec.selector.matchLabels字段中找到的键值对列出我的部署。
使用普通的labels来做这个很容易，但我找不到一种方法来匹配/获取满足以下条件的部署：在以下部分中存在某个特定的key=value
spec:[...]selector:matchLabels:app: myappprocess: webrelease: myrelease
似乎不能使用ListOptions来实现这一点。
英文:
I want to list my deployments based on a key value pair found in the .spec.selector.matchLabels field.
Doing so using the plain labels is easy, but I could not find a way to match / fetch the deployment that satisfies the condition that a certain key=value is present in the following section
spec:[...]selector:matchLabels:app: myappprocess: webrelease: myrelease
Does not seem this can be done using the ListOptions

- 和 https://github.com/kubernetes/kubernetes/issues/53459
你需要在客户端进行过滤：
depl, err := clientset.AppsV1().Deployments("some_namespace").List(context.Background(), metav1.ListOptions{})if err != nil {panic(err.Error())}for _, item := range depl.Items {if item.Spec.Selector.MatchLabels["app"] == "myapp" {fmt.Println("找到了")}}

It is not supported:

- and https://github.com/kubernetes/kubernetes/issues/53459
You have to filter on the client side:
depl, err := clientset.AppsV1().Deployments("some_namespace").List(context.Background(), metav1.ListOptions{})if err != nil {panic(err.Error())}for _, item := range depl.Items {if item.Spec.Selector.MatchLabels["app"] == "myapp" {fmt.Println("found it")}}
