Environments let you deploy different versions of a container to different environments. For example you may first want to deploy a specific version to your development environment, then to the test or staging environment before you publish a container on the “live” environment.

A user with super user access can configure the list of available environments in the plugin settings by going to “Administration > System > General settings”.
