K8S:服务未更改，但未列出

Question

>我正在尝试在kubernetes上创建一个服务，但尽管没有打印错误，但我无法列出该服务;

与minikube一起在本地工作

*$ kubectl get services
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   4h
/home/pkara/Workspace/gitlab/my-minikube
*$ kubectl apply -f mydb.yaml 
service/mydatabase unchanged
/home/pkara/Workspace/gitlab/my-minikube
*$ kubectl get services
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   4h

以下是使用的清单：

---
apiVersion: v1
kind: Service
metadata:
name: mydatabase
namespace: esa-local-dev
labels:
app: mydatabase
spec:
ports:
- name: mydatabase-port
port: 3306
targetPort: 3306
selector:
app: mydatabase
clusterIP: None
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: mydatabase-deployment
labels:
app: mydatabase
spec:
selector:
matchLabels:
app: mydatabase
strategy:

Answer 1

服务是在esa-local-dev命名空间上创建的。在你的 yaml 中，你有：

apiVersion: v1
kind: Service
metadata:
name: mydatabase
namespace: esa-local-dev
...

您可以通过运行来查看服务，

$ kubectl get services -n esa-local-dev
