   [[installation-rpm]]
  
positive.code: memory if you intend to host a lot of projects. See the different installation
  modes (Docker, RPM, etc.) to know how to setup the memory settings.
  
  Ontrack stores its data in a local H2 database. This one can grow up to 500 Mb
  for big volumes (hundreds of projects).
  
  [[installation-docker]]
  === Installing using Docker
  
negative.code: 
  Two volumes are defined:
  
  * `/var/ontrack/data` - contains some working files but also the log files.
  * `/var/ontrack/conf` - contains the <<configuration-properties,configuration files>> for Ontrack (see later).
