  1. apply 使用patch 方法
  2. replace 使用update方法
  3. replace --force 使用了先delete再create方法

patch有以下策略https://kubernetes.io/zh/docs/tasks/manage-kubernetes-objects/update-api-object-kubectl-patch/:

  1. json: json patch 
    [
{
    "op" : "replace" ,
    "path" : "/users/0/email" ,
    "value" : "alice@wonderland.org"
},
]
  2. merge: json merge patch 
    {
"a":"z",
"c": {
    "f": null
}
}

  3. strategic: strategic merge patch

    前两者参考https://erosb.github.io/post/json-patch-vs-merge-patch/
