Kubernetes 服务 etcd 参考

  • 772

如果对 kubernetes 服务有相当了解的人可以向我证实，一旦你需要创建一个新服务，kubernetes 就会在 etcd 数据库上推送它的引用，以及请求它的 URL 是什么，那就太好了！！！

    所有数据都由 apiserver 保存在 etcd 中。

    您可以通过以下方式获取服务列表：

    kubectl get services

    如果你想从 etcd 获取定义：

        # etcdctl --peers http://$(hostname):2379 ls
    /coreos.com
    /registry
    # etcdctl --peers http://$(hostname):2379 ls /registry
    /registry/namespaces
    /registry/pods
    /registry/ranges
    /registry/serviceaccounts
    /registry/services
    /registry/controllers
    /registry/events
    /registry/minions
    # etcdctl --peers http://$(hostname):2379 ls /registry/services
    /registry/services/endpoints
    /registry/services/specs
    # etcdctl --peers http://$(hostname):2379 ls /registry/services/endpoints
    /registry/services/endpoints/default
    # etcdctl --peers http://$(hostname):2379 ls /registry/services/endpoints/default
    /registry/services/endpoints/default/kube-dns
    /registry/services/endpoints/default/kubernetes
    # etcdctl --peers http://$(hostname):2379 get /registry/services/endpoints/default/kube-dns
    {"kind":"Endpoints","apiVersion":"v1","metadata":{"name":"kube-dns","namespace":"default","selfLink":"/api/v1/namespaces/default/endpoints/kube-dns","uid":"194eacb0-8465-11e5-ab8c-005056a3274a","resourceVersion":"4787638","creationTimestamp":"2015-11-06T09:02:25Z","labels":{"k8s-app":"kube-dns","kubernetes.io/cluster-service":"true","kubernetes.io/name":"KubeDNS"}},"subsets":[]}
