Allow deployment of Single Node Openshift environments #55

Open ivandov opened 9 months ago

ivandov commented 9 months ago

Description

For simpler dev/test scenarios and to enable a low-cost deployment option for our CI scenarios, we should look into deploying Single Node Openshift (SNO) clusters.

Potential Solutions

  1. Provide simpler ARM/Cloudformation templates that only bring up a VM in an existing VNet or VPC then run the openshift-installer.
  2. Extend the existing automation templates and allow the user to select which deployment model to use.

Additional Context

If adding this deployment as an option into an existing template causes many inputs to no longer be required, it may be best to support this with two different sets of templates. This is due to the ARM/Cloudformation UIs not having an ability to dynamically show/hide fields based on user inputs.

@ivandov As there is no additional cost associated with creating a VNet (in Azure) or VPC (in AWS), do you recommend to use an existing VNet or VPC still? For a better segregation of resources, can a new VNet be created with only one subnet for Bootstrap VM? Please provide your thoughts.
