title: Getting ssh-keygen in Alpine docker
body: <p>for node-red new functionality Projects - where one can sync with a git repo, I need <code>ssh-keygen</code> in my Alpine docker Image. According to <a href="https://pkgs.alpinelinux.org/contents?file=ssh-keygen&amp;path=&amp;name=&amp;branch=v3.6&amp;repo=main&amp;arch=x86_64" rel="noreferrer">Alpine Linux packages for v3.6</a>, it is in the <code>openssh-keygen</code> package.<br>
  Thus, I added the RUN commands as follows in the Dockerfile, with no luck.</p>
  
  <pre><code>......
  RUN   apk update &amp;&amp; \
        apk add --no-cache \
        openssh-keygen
  ......
  </code></pre>
  
  <p>I then test to see if it gets into the Image, by creating a container from the Image, doing a <code>docker exec -it containername sh</code> and then typing <code>ssh-keygen</code> - but do not find it.<br>
  Also not working if I replace <code>openssh-keygen</code> with <code>openssh</code> under the RUN command in the Dockerfile.</p>
  
  <p>Can someone please point me in the right direction?</p>
