curl命令更新k8s cr status

因为status是cr的subresource，所以不支持使用kubectl直接更新cr status，一般由controller来更新status。
在KubeBuilder框架中，使用xxx.Status().Update(xxx)方式来更新status。

cluster cr

创建crd和cr

cat <<EOF | kubectl create -f -
apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  name: fruits.crd.io
spec:
  group: crd.io
  versions:
  - name: v1
    served: true
    storage: true
    schema:
      openAPIV3Schema:
        type: object
        properties:
          spec:
            type: object
            properties:
              location:
                type: string
          status:
            type: object
            properties:
              enable:
                type: boolean
  scope: Cluster
  names:
    plural: fruits
    singular: fruit
    kind: Fruit
EOF

cat <<EOF | kubectl create -f -
apiVersion: crd.io/v1
kind: Fruit
metadata:
  name: apple
spec:
  location: "beijing"
EOF

修改cluster粒度cr status

kubectl proxy &
crName=apple
curl -H "Content-Type: application/merge-patch+json" -XPATCH -d '{"status":{"enable":true}}' http://127.0.0.1:8001/apis/crd.io/v1/fruits/$crName
kill `ps -ef | grep 'kubectl proxy' | grep -v grep | awk '{print $2}'`

 

namespace cr

把scope从Cluster改成Namespaced，cr中增加namespace: default。

crName=apple
namespace=default
curl -H "Content-Type: application/merge-patch+json" -XPATCH -d '{"status":{"enable":true}}' http://127.0.0.1:8001/apis/crd.io/v1/namespaces/$namespace/fruits/$crName
