K8SCACHE
local cache for kubernetes apiserver cache
k8scache is based on client-go informer
Feature
support resource list:
- namespace
- pod
- node
- service
- replicaSet
- deployment
- daemonSet
- statefulSet
- event
- endpoints
Usage
func TestSimple(t *testing.T) {
cli, err := NewClient()
assert.Equal(t, err, nil)
err = cli.BuildForKubecfg()
assert.Equal(t, err, nil)
cc, err := NewClusterCache(cli)
assert.Equal(t, err, nil)
pods, err := cc.ListPods()
assert.Equal(t, err, nil)
assert.Greater(t, len(pods.Items), 0)
cc.Start()
cc.SyncCache()
nslist, err := cc.GetNamespaces()
assert.Equal(t, err, nil)
assert.Greater(t, len(nslist), 0)
fmt.Printf("namespace list %v \n\n", nslist)
nodes, err := cc.GetNodes()
assert.Equal(t, err, nil)
assert.Greater(t, len(nodes), 0)
