how to install docker in sles 12?
<p>I want to install docker stable version in my suse system (version sles 12). For installing docker in suse system, need to add repository of docker. </p>

<p>I didn't found any url (repository url) for adding docker repository of version 1.6. I found docker version 1.12 but it is not working in my case. I removed docker repository now.</p>

<p>can anyone suggest me how I can add correct repository and install docker further in my system?</p>

<p>edit- sample commands and output</p>

<p><strong>docker -v</strong></p>
