Trouble with host url parameterization

[jasont41]

I am attempting to parameterize a databricks yaml so I can deploy it to multiple databricks accounts via Gitlab CICD, and have ran into a snag when parameterizing the workpace host value. 

My variable block looks like this: 

variables:

    databricks_host:

        description: Databricks host URL

        default: <my_url>

And I reference the variable like so: 

workspace:

    host: ${var.databricks_host}

I set the variable with 

BUNDLE_VAR_databricks_host: <url> 

in the Gitlab CI pipeline. I have verified that this pattern works with other variables, it is just this variable reference that won't resolve. 

This is the error I get: 

Error: failed during request visitor: parse "https://${var.databricks_host}": invalid character "{" in host name

53Name: <workflow_name>

54Target: dev

55Workspace:

56 Host: ${var.databricks_host}

57Found 1 error

I am beginning to think that this particular value cannot be assigned with a variable, but I haven't found anything in the documentation to backup that assumption. Any help would be greatly appreciated!

Hi @jasont41 ,

Your assumption is correct. You can't use variable for host mapping. You can find information about it in the following documentation entry:
