1.1 POD
1.1.1 创建一个pod
定义一个pod (分层使用两个空格，勿用tab键)
# vim nginx.yaml
apiVersion: v1 # 必选， API 的版本号
kind: Pod # 必选，类型 Pod
metadata: # 必选，元数据
name: nginx # 必选，符合 RFC 1035 规范的 Pod 名称
spec: # 必选，用于定义 Pod 的详细信息
containers: # 必选，容器列表
- name: nginx # 必选，符合 RFC 1035 规范的容器名称
image: nginx:1.15.12 # 必选，容器所用的镜像的地址
ports: # 可选，容器需要暴露的端口号列表
- containerPort: 80 # 端口号
创建pod
# kubectl create -f nginx.yaml pod/nginx created
查看pod状态
# kubectl get po ### 使用 po 或者 pod 都可以 NAME READY STATUS RESTARTS AGE nginx 1/1 Running 0 47s
使用kubectl run 创建一个pod
[root@k8s-master03 ~]# kubectl run nginx-run --image=nginx:1.15.12 pod/nginx-run created
##使用--dry-run 创建
[root@k8s-master03 ~]# kubectl run nginx --image=nginx:1.15.12 -oyaml --dry-run > pod.yaml
W1217 17:17:26.985672 75520 helpers.go:622] --dry-run is deprecated and can be replaced with --dry-run=client.
[root@k8s-master03 ~]#
[root@k8s-master03 ~]# cat pod.yaml
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null
labels:
run: nginx
name: nginx
spec:
containers:
- image: nginx:1.15.12
name: nginx
resources: {}
dnsPolicy: ClusterFirst
restartPolicy: Always
status: {}
删除pod
[root@k8s-master03 ~]# kubectl delete -f nginx.yaml ##method1 指定yaml删除 pod "nginx" deleted [root@k8s-master03 ~]# kubectl get po NAME READY STATUS RESTARTS AGE nginx-run 1/1 Running 0 93s [root@k8s-master03 ~]# kubectl delete po nginx-run ##method2 指定pod NAME删除 pod "nginx-run" deleted [root@k8s-master03 ~]# kubectl get po No resources found in default namespace.
查看pod的所有资源信息
