The old commands still work, but the new ones make it easier to get started with Docker. The original version of this article listed the old names. I’ve updated the article to use the management command names based on reader suggestions. Note that this change only introduces two command name changes — in most cases it just means adding <code class="hp jo jp jq jr b">container</code> or <code class="hp jo jp jq jr b">image</code> to the command. A mapping of the commands is <a href="http://blog.arungupta.me/docker-1-13-management-commands/" class="dc by gz ha hb hc" target="_blank" rel="noopener">here</a>.</p><h1 id="ca9c" class="ia ib ef at as ic id ie if ig ih ii ij ik il im in" data-selectable-paragraph="">Wrap</h1><p id="4d6b" class="gl gm ef at gn b go io gq ip gs iq gu ir gw is gy" data-selectable-paragraph="">If you are just getting started with Docker, these are the three most important commands:</p><p id="d0a2" class="gl gm ef at gn b go gp gq gr gs gt gu gv gw gx gy" data-selectable-paragraph=""><code class="hp jo jp jq jr b"><strong class="gn iw">docker container run my_image</strong></code> — Create a new container and start it.
