Ruby Versions

Jelastic PaaS supports all of the latest major releases of the Ruby engine and provides the regular updates of the appropriate stacks, keeping them up-to-date. Currently, the following Ruby versions are available:
  • 2.2.10
  • 2.3.7
  • 2.4.4
  • 2.5.1

You can choose the required one during environment creation and quickly switch between them afterward.

Change Ruby Version

For the already existing environments, you can change the Ruby version by redeploying container(s):

1. There are two options to access container update dialog:

  • via the topology wizard (use the Change environment topology button next to the appropriate environment) by clicking on the stack/tag version in the central dialog part

2. In the opened window, adjust the following settings:
  • Tag - allows choosing the needed Ruby version
  • Keep volumes data - saves data in volumes
  • Simultaneous or Sequential deployment with delay (for scaled servers only) - defines whether all containers within a layer should be redeployed at once or one-by-one, to avoid downtime
