title: Grep command to extract a kubernetes pod name
body: <p>I am currently working on a <code>bash</code> script to reduce the time it takes for me to build the <code>db</code> for a project. 
  Currently I have several databases running in the same namespace and I want to extract only the specific pod name.</p>
  
  <p>I run <code>kubectl get pods</code></p>
  
  <pre><code>NAME                        READY   STATUS    RESTARTS   AGE
  elastic                     1/1     Running   0          37h
  mysql                       1/1     Running   0          37h
  </code></pre>
  
  <p>Now I want to save one of the pod names.</p>
  
  <p>I'm currently running this <code>foo=$(kubectl get pods | grep -e "mysql")</code>
  and it returns <code>mysql                  1/1     Running   0          37h</code> which is the expected results of the command. Now I just want to be able to extract the pod name as that variable so that I can pass it on at a later time.</p>
