»CentOS Requirements for Terraform Enterprise
When installing Terraform Enterprise on CentOS Linux, ensure you meet the following requirements:
»Can I use the Docker version in the Extra Packages for Enterprise Linux repository?
Sure! Just be sure to modify the default
»Which storage driver should I use?
overlay2 storage driver.
»Can an installation where
docker info says that I’m using devicemapper with a loopback file work?
No. This is an installation that Docker provides as sample and is not supported by Terraform Enterprise due to the significant instability in it. Docker themselves do not suggest using this mode.
»How do I know if an installation is in devicemapper loopback mode?
Run the command
docker info | grep dev/loop. If there is any output, you’re in devicemapper loopback mode. Docker may also print warning about loopback mode when you run the above command, which is another indicator.
