Debug Output

azurerm_redis_cache.this: Still creating... [1h10m30s elapsed]

Error: waiting for the create of Redis Cache ... Code="Failed" Message="The async operation failed."

If I try run terraform plan & apply again I hit

Error: A resource with the ID "/subscriptions/..../resourceGroups/.../providers/Microsoft.Cache/Redis/my-redis" already exists - to be managed via Terraform this resource needs to be imported into the State. Please see the resource documentation for "azurerm_redis_cache" for more information.

Expected Behaviour

azurerm_redis_cache should not fail if Redis does end up getting created.

Actual Behaviour

azurerm_redis_cache fails. But I can see in the Azure portal that Redis goes on and gets created successfully.

Steps to Reproduce

terraform apply

[placyd]

The same here. Without setting virtual network configuriation works.

[dkirrane]

Still hitting this on Terraform v0.14.9

    azurerm = {
      source = "hashicorp/azurerm"
      version = "2.56.0"
    }

[kyoshiro]

Problem still exists with:

azurerm = {
  version = "~> 2.64"
  source  = "hashicorp/azurerm"
}

[dzmitry-lahoda]

I observe Debug Output as described while creating redis similar to above, but without subnetwork applied. I check manually azure portal and see redis is created here. but terraform does not see it. so i do other settings, these can have some influence

[dzmitry-lahoda]

issue may be related to https://github.com/hashicorp/terraform-provider-azurerm/pull/14208 about getting wrong redis id path, so not tested

[DesislavaNPetrova]

Problem still exist with:

azurerm = { version = "~> 3.6.0" source = "hashicorp/azurerm" }
