OLM是一组cluster资源的集合，用来管理一个operator的lifecycle.
安装olm
假设你已经安装operator-sdk
operator-sdk olm install operator-sdk olm status 讯享网
我的输出为
讯享网INFO[0000] Fetching CRDs for version "v0.21.2" INFO[0000] Fetching resources for resolved version "v0.21.2"
使用olm获取operator list
kubectl get packagemanifest -n olm安装一个operator
- 创建一个group
讯享网carawang@carawangs-MacBook-Pro olm % kubectl apply -f operatorgroup.yaml operatorgroup.operators.coreos.com/og-single created carawang@carawangs-MacBook-Pro olm % cat operatorgroup.yaml kind: OperatorGroup apiVersion: operators.coreos.com/v1 metadata: name: og-single namespace: default spec: targetNamespaces: - default
2. 创建一个订阅
carawang@carawangs-MacBook-Pro olm % kubectl apply -f subscription.yaml subscription.operators.coreos.com/etcd created carawang@carawangs-MacBook-Pro olm % cat subscription.yaml apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: etcd namespace: default spec: channel: singlenamespace-alpha installPlanApproval: Automatic name: etcd source: operatorhubio-catalog sourceNamespace: olm startingCSV: etcdoperator.v0.9.2
