如何使用指南针连接到 mongodb replicaset (k8s)

我们刚刚重新创建了您的设置.一切都很好

$ k create ns mongo-test
namespace/mongo-test created

$ k -n mongo-test create -f Mongo-svc-sts.yaml
statefulset.apps/mongo created
service/mongo-headless created

结果

$ k -n mongo-test get all
NAME          READY   STATUS    RESTARTS   AGE
pod/mongo-0   1/1     Running   0          44s
pod/mongo-1   1/1     Running   0          40s
pod/mongo-2   1/1     Running   0          27s

NAME                     TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)     AGE
service/mongo-headless   ClusterIP   None         <none>        27017/TCP   13m

NAME                     READY   AGE
statefulset.apps/mongo   3/3     45s

端口转发

$ k -n mongo-test port-forward svc/mongo-headless 27018:27017
Forwarding from 127.0.0.1:27018 -> 27017
Forwarding from [::1]:27018 -> 27017
