I work in a company and we are reviewing Docker. We have ~50 web sites on PHP. Some of them use PHP 5.4, some PHP 5.6 and we try to migrate them to PHP7, the new sites are on PHP7 )). The database is on a separate server.
My question is if there are some benefits to create containers :
1 for apache
1 for each PHP version or per site is better
I want to hear some feedback from the people that tried Docker for the same purpose.
