## Plugin Spec
4+
5+
PluginSpec defines the desired state of Plugin
6+
7+
```
8+
type PluginSpec struct {
9+
Type string `json:"type,omitempty"`
10+
Data string `json:"data,omitempty"`
11+
Action string `json:"action,omitempty"`
12+
Scope string `json:"scope,omitempty"`
13+
}
14+
```
15+
16+
1. for `PluginSpec.Type`: plugin type,currently only supported "SHELL".
17+
2. for `PluginSpec.Data`: plugin`s real data, sealer will use it to do actual action.
18+
3. for `PluginSpec.Scope`: plugin`s scope, it is usually the role name, support use '|' to specify multiple scopes.
19+
4. for `PluginSpec.Action`: phase of this plugin will run. below is the phase list we currently supported.
20+
21+
plugin will be executed by `PluginSpec.Name` in alphabetical order at the same stage.
22+
23+
The following is a detailed introduction for plugin action.
24+
25+
