I see that the change done 7 years ago was to overcome the error "undefined method cid' for nil:NilClass" when the director does not support the CPI version, but they already have included unit tests for that, and are taking the minimum version supported_cpi_version = [cpi_api_version, MAX_SUPPORTED_CPI_VERSION].min into account. So I think it should be OK to get rid of the case statement. |

What is this change about?
Bosh director should handle all CPI API Versions correctly.
This will solve the failing BATS for the aws cpi: https://bosh.ci.cloudfoundry.org/teams/main/pipelines/bosh-aws-cpi/jobs/bats
Please provide contextual information.
The AWS CPI API Version was recently bumped to version 3. This leads to issues when the director tries to create a vm because the response is cleared unexpectedly as previously there is only handling for version 1 and 2. Back then the update to support version 3 was only done for the create_stemcell method. I changed this to be compatible with all versions higher than 2. To me this change appears pretty straightforward, however I could see that this coding was like this already in the past, but was changed to the case statement. This was done 7 years ago so probably the reason why this was changed is not valid anymore? Otherwise we could also change it back to a case statement instead just including version 3.
