Kubernetes: describe: Get current Pod configuration

‘kubectl describe pod {podName}’ command is used to get the current Pod configuration. This command queries ‘etcd’ (etcd is a Kubernetes key-value database) and returns all the information about the given resource.

 

Let’s create a Pod from yml definition file and see the configuration using ‘describe’ command.

 

employeeServicePod.yml

apiVersion: v1
kind: Pod
metadata:
  name: employee-service
  labels:
    app: employee-service
    author: krishna
    serviceType: webservice
spec:
  containers:
    - name: employee-service-container
      image: jboss/wildfly

Now create a pod by executing below command.

kubectl create -f employeeServicePod.yml

 

$kubectl create -f employeeServicePod.yml
pod/employee-service created

 

Let’s describe the pod ‘employee-service’ by executing the below command.

 

kubectl describe pod employee-service

$kubectl describe pod employee-service
