cronjobs
customresourcedefinition (aka ‘crd’)
daemonsets (aka ‘ds’)
deployments (aka ‘deploy’)
endpoints (aka ‘ep’)
events (aka ‘ev’)
horizontalpodautoscalers (aka ‘hpa’)
ingresses (aka ‘ing’)

limitranges (aka ‘limits’)
namespaces (aka ‘ns’)
networkpolicies (aka ‘netpol’)

三、可选参数

用不同的格式查看

-o wide/yaml/json

看指定标签的pods，支持’=’, ‘==’, and ‘!=’操作符

-l key=value

查看指定的命名空间

-n 命名空间

四、 示例

# 查看Master状态
kubectl get componentstatuses

# 查看所有命名空间
kubectl get namespace

# 列出所有的pods
kubectl get pods

# 显示更多的pods列表信息(例如 pod的ip和所处的node)
kubectl get pods -o wide

# 列出名字为web的rc
kubectl get replicationcontroller web

# 获取名字为web-pod-13je7的pod的信息，并以json格式输出
kubectl get -o json pod web-pod-13je7

# 根据pod文件查找pod，并以json格式输出
kubectl get -f pod.yaml -o json

# 获取pod容器的状态
kubectl get -o template pod/kube-dns-795f5f6f9c-ldxxs --template {{.status.phase}}

# 同时获取所有的rc和service
kubectl get rc,services

# 获取符合条件的所有rc,svc,pod
kubectl get rc/web service/frontend pods/web-pod-13je7

# 获取所有resource
kubectl get all
