CirrusGrid 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:
1. Click the New Environment button at the top of the dashboard.
2. Within the opened topology wizard, switch to the Ruby tab and select the desired application server (Apache or NGINX). Next, choose the engine version with the appropriate drop-down list in the central part of the frame.
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
with the appropriate Rededeploy container(s) button next to the required node/layer
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
3. Click Redeploy and confirm via the appeared pop-up frame.
In a minute, the Ruby version of your node(s) will be updated.
