Description Abhinav Dahiya 2020-05-19 16:32:08 UTC

Description of problem:

When every the installer fails to create resources using terraform, it outputs the errors from terraform as-is but the actual FATAL error is completely generic and doesn't provide any insight into what could have cause the error.

see https://storage.googleapis.com/origin-ci-test/pr-logs/pull/openshift_cluster-api-provider-azure/130/pull-ci-openshift-cluster-api-provider-azure-master-e2e-azure/435/artifacts/e2e-azure/container-logs/setup.log

```
level=fatal msg="failed to fetch Cluster: failed to generate asset \"Cluster\": failed to create cluster: failed to apply using Terraform"
```

and the tf error
```
level=error
level=error msg="Error: Error Creating/Updating Subnet \"ci-op-641yvqj0-64576-lx9tt-worker-subnet\" (Virtual Network \"ci-op-641yvqj0-64576-lx9tt-vnet\" / Resource Group \"ci-op-641yvqj0-64576-lx9tt-rg\"): network.SubnetsClient#CreateOrUpdate: Failure sending request: StatusCode=0 -- Original Error: autorest/azure: Service returned an error. Status=<nil> Code=\"AnotherOperationInProgress\" Message=\"Another operation on this or dependent resource is in progress.

level=error
level=error msg="  on ../tmp/openshift-install-786806570/vnet/vnet.tf line 22, in resource \"azurerm_subnet\" \"worker_subnet\":"
level=error msg="  22: resource \"azurerm_subnet\" \"worker_subnet\" {"
level=error
```

The installer should provide more context in the error reported to the error, maybe summarize the actual error and provide user with some action item.


Steps to Reproduce:

An easy way is to create an azure cluster with invalid release image, this causes the bootstrap to fail and the master nodes cannot get their ignition.

this manifests as a terraform error `OSProvisioningTimedOut` which doens't really explain anything.

Comment 3 Mike Gahagan 2020-06-02 14:41:45 UTC

Looks like error messages are better now. Here is a failure caused by referencing a vnet that is in a different region than the region that was specified for the cluster:
