Docker Desktop启动mysql

1. docker和kubernetes启动后，通过命令行检查k8s集群状态

➜  ~ kubectl cluster-info
Kubernetes control plane is running at https://kubernetes.docker.internal:6443
CoreDNS is running at https://kubernetes.docker.internal:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
➜  ~ kubectl get nodes
NAME             STATUS   ROLES           AGE     VERSION
docker-desktop   Ready    control-plane   2m18s   v1.24.1
➜  ~ kubectl get pods
No resources found in default namespace.
➜  ~ kubectl get pods -A

2. 创建mysql

➜  k8s kubectl create -f mysql.yaml
service/mysql created
deployment.apps/mysql created
persistentvolume/mysql-pv-volume created
persistentvolumeclaim/mysql-pv-claim created
➜  k8s
➜  k8s kubectl get pod
NAME                    READY   STATUS    RESTARTS   AGE
mysql-9f9d74bb5-g2hm4   1/1     Running   0          2m19s
