title: Is there something like `helm exec`?
body: <p>I use the following <code>helm</code> (2.4.2) commands in my <code>gitlab-ci.yml</code> script:</p>
  
  <pre><code>- helm upgrade --install myapp-db --wait --set postgresUser=postgres,postgresPassword=postgres,postgresDatabase=myapp stable/postgresql
  - helm upgrade --install myapp-web ./myapp-chart --wait --set env.DATABASE_URL="${DATABASE_URL}"
  </code></pre>
  
  <p>It's part of a deployment to my staging/review environment. After the above commands complete, I would like to execute commands against the <code>my-app</code> pod to create/migrate the database. At the moment this is achieved through the use of an <code>initContainer</code> (defined in the referenced yaml file). But I would prefer the logic to be part of the CI script - so I don't have to have a separate deployment file for production.</p>
  
  <p>Is there a way to do this with <code>helm</code>? Or is my only option to use <code>kubectl exec</code>? If I use <code>kubectl exec</code>, is there an easy way to get the name of the pod using <code>helm</code>?</p>
