ruby - Chef : Can I share common per-environment run list items?

Question

我在 Chef 中使用环境，我想使用每个环境的运行列表。问题是我不想重复自己(就像我现在做的那样)。示例:

{
  "name": "myapp",
  "default_attributes": {
  },
  "json_class": "Chef::Role",
  "env_run_lists": {
    "production": [
      # Has less packages because services are spread across specialized nodes
      "role[base]",
      "recipe[mysql::client]",
      "recipe[myapp]"
    ],
    "staging": [
      # Has less packages because services are spread across specialized nodes
      "role[base]",
      "recipe[mysql::client]",
      "recipe[myapp]"
    ],
    "development": [
      "role[base]",
      "recipe[mysql::client]",
      "recipe[myapp]",
      "role[utility]",
      "role[cache]"
    ]
  },
  "run_list": [

  ],
  "description": "The myapp.com core application role",
  "chef_type": "role",
  "override_attributes": {

  }
}

有什么方法可以避免重复此操作？

      "role[base]",
      "recipe[mysql::client]",
      "recipe[myapp]",

我只想避免环境运行列表不同步和破坏部署。

目前，没有。角色纯粹是声明性的，而不是动态的。您可以创建一个包含这三项的角色，并将其包含在每个环境的运行列表中。
