Starteed: Starting a PHP-based SaaS on Mesosphere's DC/OS
summary
A PHP7 SaaS deployed with Docker, MariaDB and Marathon on Mesosphere DC/OS is presented as providing zero-downtime and high availability, but the talk details important caveats: it uses Marathon-LB and ACME for SSL, hits a 100-certificate ACME limit so wildcard certificates are used, and certificate posts cause about 12 seconds of downtime. The cluster consists of one master and six agents hosting 250 platforms, an event generated ~€10k in 45 seconds, and operational notes include Docker garbage collection and exec support arriving only in DC/OS 1.9.
