如何比较go模板中的字符串?

回答问题

.metadata.labels.app"myapp"

命令:

kubectl get pods -o go-template --template="{{range .items}}{{if eq .metadata.labels.app "myapp"}}{{.metadata.name}} {{end}}{{end}}"

它给出了一个错误:

输出:1:未定义函数“myapp”

结构如下所示:

- apiVersion: v1
  kind: Pod
  metadata:
    creationTimestamp: 2017-09-15T08:18:26Z
    generateName: myapp-2830765207-
    labels:
      app: myapp
      pod-template-hash: "2830765207"
    name: myapp-2830765207-dh359
    namespace: default

"myapp"

kubectl get pods -o go-template --template='{{range .items}}{{if eq .metadata.labels.app "myapp"}}{{.metadata.name}} {{end}}{{end}}'
