Kubernetes使用kubectl describe命令查看信息

官方说明如下

  $ kubectl describe TYPE NAME_PREFIX
  
 will first check for an exact match on TYPE and NAME_PREFIX. If no such resource exists, it will output details for
every resource that has a name prefixed with NAME_PREFIX.

Use "kubectl api-resources" for a complete list of supported resources.

Examples:
  # Describe a node
  kubectl describe nodes kubernetes-node-emt8.c.myproject.internal
  
  # Describe a pod
  kubectl describe pods/nginx
  
  # Describe a pod identified by type and name in "pod.json"
  kubectl describe -f pod.json
  
  # Describe all pods
  kubectl describe pods
  
  # Describe pods by label name=myLabel
  kubectl describe po -l name=myLabel
  
  # Describe all pods managed by the 'frontend' replication controller (rc-created pods
  # get the name of the rc as a prefix in the pod the name).
  kubectl describe pods frontend

日常使用比较多的有：
查看deployment信息，可以查看其yaml：

kubectl describe deployment apm-democ-demoa -n springcloudtest
