khnazaretyan opened a new pull request #3651: Fix simulator docker db deploy issue (apache#3397)
URL: https://github.com/apache/cloudstack/pull/3651
 
 
   ## Description
   <!--- Describe your changes in detail -->
   As the latest docker image in dockerhub is built from master branch, I thought it would be correct to open PR into a master branch (and not to release, if inacceptable, please suggest the correct one).
   
   Fixes: #3397
   
   The latest cloudstack/simulator image is not working causing issue #3397. 
   The build was incomplete as mysql 5.7 is failing to start during docker build, thus DB is not deployed.
   The command `find /var/lib/mysql -type f -exec touch {} \;` is a workaround for the issue wich causes mysqld 5.7 to crash after start.
   Putting VOLUME instruction before starting mysql also solves this problem but does not allow any other changes to the folder during build.
   
   There are other also options that might be discussed:
   1. Setting `VOLUME /var/lib/mysql` instruction in Dockerfile and and importing the db during each container run (the start of the container will take longer).
   2. Try to download and install mysql v5.5 from archives during docker build (limited to 5.5)
   
   Other ideas/input will be much appreciated.
