Cant change datalake image to CentOS 7

[hndordix]

I am currently automating the creation of a Cloudera CDP environment with Azure as the cloud provider. I have to use CentOS7 as the operating system. To change the operating system and the corresponding image of the data lake, I would use the ‘datalake_image’ variable of the cdp-deploy module. However, to be able to use this, ‘datalake_version’ must be set to null. When compiling, I always get the error that ‘datalake_version’ must not be null. How else can I change the image of the datalake?

Error message:
│ Error: Invalid function argument

│ on modules\terraform-cdp-deploy\variables.tf line 226, in variable "datalake_version":

Hi @hndordix,

As part of PR #68, we've updated the validation on the datalake_version input variable to allow null.
We have also created a 0.7.1 release tag for this version of the modules.

When you get a chance can you test if this resolves your issues?
I suspect you may also need the changes in PR #57 as this allows the major OS version to be specified. We hit some issues when testing this which might require an update on the CDP provider.
