运行 nginx deployment

编写 yml

nginx-deployment.yml

apiVersion: apps/v1
kind: Deployment
metadata:
    name: nginx-deployment
spec:
    replicas: 2
    selector:
        matchLabels:
            app: nginx-deployment
    template:
        metadata:
            labels:
                app: nginx-deployment
        spec:
            containers:
              - name: nginx
                image: nginx
运行 yml

kubectl create命令，是先删除所有现有的东西，重新根据yaml文件生成新的。

所以要求yaml文件中的配置必须是完整的。

$ kubectl create -f nginx-deployment.yml
deployment.apps/nginx-deployment created

kubectl apply命令，根据配置文件里面列出来的内容，升级现有的。

所以yaml文件的内容可以只写需要升级的属性。

$ kubectl apply -f nginx-deployment.yml
deployment.apps/nginx-deployment created
删除资源
$ kubectl delete -f nginx-deployment.yml
deployment.apps "nginx-deployment" deleted

运行 nginx pod

编写 yml

nginx-pod.yml

apiVersion: v1
kind: Pod
metadata:
    name: nginx-pod
spec:
    containers:
      - name: nginx
        image: nginx
运行 yml
$ kubectl apply -f nginx-pod.yml
pod/nginx-pod created
查看资源
$ kubectl get pod
NAME        READY   STATUS    RESTARTS   AGE
nginx-pod   1/1     Running   0          2m
删除资源
$ kubectl delete -f nginx-pod.yml
pod "nginx-pod" deleted

通过 Dashboard 部署

查看

$ kubectl get deployments -A
NAMESPACE              NAME                        READY   UP-TO-DATE   AVAILABLE   AGE
default                nginx-deployment            2/2     2            2           77m

删除

$ kubectl delete deployments nginx-deployment --namespace=default
deployment.apps "nginx-deployment" deleted
