title: Devops with OpenShift
body: <p>I'm trying to build a new app by using a docker image from the book Devops With OpenShift
  so as per the content from the book  page 19
  the command is</p>
  <pre><code>oc new-app devopswithopenshift/welcome:latest --name=myapp
  </code></pre>
  <p>so the <code>devopswithopenshift/welcome:latest</code> needs to be firstly built and pushed to the docker hub.
  I pulled the GIT code from <a href="https://github.com/devops-with-openshift/welcome" rel="nofollow noreferrer">https://github.com/devops-with-openshift/welcome</a>
  and ran the command <code>C:\Docker\welcome\foo&gt;docker build -t welcome .</code></p>
  <p>Here is the response</p>
  <pre><code>failed to solve with frontend dockerfile.v0: failed to create LLB definition: pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed
  </code></pre>
  <p>When i looked into the Dockerfile</p>
  <p>It has <code>FROM welcome/ops:latest</code>
  so it is trying to pull <code>welcome/ops</code> which is not there in the registry can the authors help resolve this</p>
  <p>Thanks
