extendworkload

Component Example

Install

1. install all crd files by make install
2. go run pkg/examples/extendworkload/main.go

Apply

When we install component.yaml, we will get such output:

2019-12-23T16:12:31.720+0800	INFO	setup	hello oam from pre hook: comp
settings: {"Description":"xxx","Protocol":"Example","Type":"Performance"}
Description: xxx
Protocol: Example
Type: Performance

Raw json data is stored in component.Spec.WorkloadSettings.Raw. In fact you could get the real type.

You could see our workloadType in pkg/examples/extendworkload/workloadtype.yaml, our schema is:

    {
       "$schema":"http://json-schema.org/draft-07/schema#",
       "type":"object",
       "description":"",
       "required":[
          "Protocol"
       ],
       "properties":{
          "Protocol":{
             "type":"string",
             "description":""
          },
          "Type":{
             "type":"string",
             "description":""
          },
          "Description":{
             "type":"string",
             "description":""
          }
       }
    }

So we could use map[string]interface{} to parse our output, so we could get more concrete data struct.

New CRD
