title: Docker context not changing (docker context use)
body: <p>I am using the command <code>docker context use</code> in order to set the active Docker context:</p>
  <pre><code>&gt; docker context use aws-context
  aws-context
  </code></pre>
  <p>However, the active Docker context does not change for some reason.</p>
  <p>When I subsequently type <code>docker context show</code>, the activated context is still the default context:</p>
  <pre><code>&gt; docker context show
  default
  </code></pre>
  <p>When I list the existing contexts, the asterisk is still behind the default context:</p>
  <pre><code>&gt; docker context ls
  NAME                TYPE                DESCRIPTION                              DOCKER ENDPOINT             
  aws-context         ecs                 (eu-west-1)                                                                  
  default *           moby                Current DOCKER_HOST based configuration  tcp://192.168.99.100:2376          
  </code></pre>
  <p>How can I change the Docker context?</p>
