Minikube-Kubernetes本地环境进行开发

启动Minikube

# 启动 minkube start # 检查状态 minikube status host: Running kubelet: Running apiserver: Running kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.100 # 访问面板 $ minikube dashboard # 访问web前端 $ kubectl proxy

获取命名空间

# kubectl get namespaces $ kubectl get ns NAME STATUS AGE default Active 156m kube-node-lease Active 156m kube-public Active 156m kube-system Active 156m

获取集群信息

$ kubectl cluster-info Kubernetes master is running at https://192.168.99.100:8443 KubeDNS is running at https://192.168.99.100:8443/api/v1/namespaces/kube-system/services/kube- dns:dns/proxy To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

获取节点信息

$ kubectl get node NAME STATUS ROLES AGE VERSION minikube Ready master 162m v1.14.1

运行nginx

# 运行nginx $ kubectl run nginx --image=nginx:1.16 --port=80 --labels="app=nginx,env=dev" # 增加新标签 # kubectl label pod $POD_NAME app2=test # 发布服务采用对外暴露节点 $ kubectl expose deployment nginx --type=NodePort

获取pods

 $ kubectl get pods # 根据标签查询 # kubectl get pods -l app=nginx NAME READY STATUS RESTARTS AGE nginx-fcb945956-t8bqq 1/1 Running 0 67s # 获取pod详细信息 # kubectl describe pods -l app=nginx

查看Pod日志

kubectl logs $POD_NAME

进入Pod中

# 查看环境 # kubectl exec $POD_NAME env $ kubectl exec -ti nginx-fcb945956-t8bqq /bin/bash

获取deployment

$ kubectl get deployment NAME READY UP-TO-DATE AVAILABLE AGE nginx 1/1 1 1 18m # 获取描述 $ kubectl describe deployment Name: nginx Namespace: default CreationTimestamp: Wed, 15 May 2019 23:29:23 +0800 Labels: app=nginx env=dev Annotations: deployment.kubernetes.io/revision: 1 Selector: app=nginx,env=dev Replicas: 1 desired | 1 updated | 1 total | 1 available | 0 unavailable StrategyType: RollingUpdate MinReadySeconds: 0 RollingUpdateStrategy: 25% max unavailable, 25% max surge Pod Template: Labels: app=nginx env=dev Containers: nginx: Image: nginx:1.16 Port: 8081/TCP Host Port: 0/TCP Environment: <none> Mounts: <none> Volumes: <none> Conditions: Type Status Reason ---- ------ ------ Available True MinimumReplicasAvailable Progressing True NewReplicaSetAvailable OldReplicaSets: <none> NewReplicaSet: nginx-fcb945956 (1/1 replicas created) Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal ScalingReplicaSet 18m deployment-controller Scaled up replica set nginx-fcb945956 to 1

获取svc(services)

# kubectl get svc $ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 3h8m nginx NodePort 10.105.192.17 <none> 80:31199/TCP 5m9s # 获取详情 $ kubectl describe services Name: kubernetes Namespace: default Labels: component=apiserver provider=kubernetes Annotations: <none> Selector: <none> Type: ClusterIP IP: 10.96.0.1 Port: https 443/TCP TargetPort: 8443/TCP Endpoints: 192.168.99.100:8443 Session Affinity: None Events: <none> Name: nginx Namespace: default Labels: app=nginx env=dev Annotations: <none> Selector: app=nginx,env=dev Type: NodePort IP: 10.105.192.17 Port: <unset> 80/TCP TargetPort: 80/TCP NodePort: <unset> 31199/TCP Endpoints: 172.17.0.5:80 Session Affinity: None External Traffic Policy: Cluster Events: <none>

1|2使用Minikube获取服务访问地址

# 获取服务url $ minikube service nginx --url # 访问测试 $ curl $(minikube service nginx --url)

1|3删除服务

# kubectl delete deployments --all $ kubectl delete deployments -l app=nginx # kubectl delete pods --all $ kubectl delete pods -l app=nginx # 删除service kubectl delete service -l app=nginx
