title: How to update azerothcore-wotlk docker container
body: <p>I'm running Azerothcore-WOTLK in docker following the official <a href="http://www.azerothcore.org/wiki/Install-with-Docker" rel="nofollow noreferrer">installation guide for AzerothCore using Docker containers</a> and I'm wondering how I can update the Azerothcore build and how to apply database updates without losing character data.</p>
  
  <p>To update the docker container I guess I should pull the latest code from Github and rebuild the containers using <code>docker-compose down</code> and <code>docker-compose up</code>, but how do I make sure my character data survives the update?</p>
  
  <p>To update the database I'm assuming that I should apply all the SQL updates found <a href="https://github.com/azerothcore/azerothcore-wotlk/tree/master/data/sql/updates" rel="nofollow noreferrer">here</a>, but is the db_assembler.sh usable for the docker container and if it is, how do I use it? What is the procedure for backing up important parts of the database before any update?</p>
