title: Installing ssh-keyscan on Alpine linux?
body: <p>In order to successfully clone a private repository into an Alpine-based docker, I needed to run the following command:
   <code>ssh-keyscan github.com &gt;&gt; ~/.ssh/known_hosts</code>.</p>
  
  <p>But since ssh-keyscan isn't part of Alpine linux (by default), I have to install it first with apk. The problem is: I dont know how - and I can't find it anywhere on Google.</p>
