title: [Docker]: Connecting PHPMyAdmin to MySQL doesnt work
body: <p>I'm trying to connect a PHPMyAdmin-Container to a MySQL-Container to view the databases.</p>
  
  <p>I have started the MySQL container via <code>$ docker run --name databaseContainer -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql</code> </p>
  
  <p>and the PHPMyAdmin-Container via <code>$ docker run --name myadmin -d --link databaseContainer:mysql -p 8080:8080 phpmyadmin/phpmyadmin</code></p>
  
  <p>When trying to login on PHPMyAdmin, I get:
   mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed: Name does not resolve</p>
  
  <p>and</p>
  
  <p>mysqli_real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name does not resolve</p>
  
  <p>By the way, I have also started a wordpress container and also linked it to mysql, there it works...</p>
