kubernetes - kubectl 使用来自 secret 配置的 env var 运行

Question

我如何发出 kubectl run从 k8s secret 配置映射中提取环境变量？

目前我有:
kubectl run oneoff -i --rm NAME --image=IMAGE --env SECRET=foo

查看 overrides run 的旗帜命令...它读作:

An inline JSON override for the generated object. If this is non-empty, it is used to override the generated object. Requires that the object supply a valid apiVersion field.

https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#run

所以在你的情况下，我想它会是这样的:

kubectl run oneoff -i --rm --overrides='
{
  "spec": {
    "containers": [
      {
        "name": "oneoff",
        "image": "IMAGE",
        "env": [
          {
            "name": "ENV_NAME"
            "valueFrom": {
              "secretKeyRef": {
                "name": "SECRET_NAME",
                "key": "SECRET_KEY"
              }
            }
          }
        ]
      }
    ]
  }
}
'  --image= IMAGE
