Always

1. Define 'shiftstack' cloud in clouds.yaml in the current directory:
```
$ grep -A 5 shiftstack clouds.yaml
 shiftstack:
    auth:
        auth_url: https://10.46.44.140:13000
        password: not_the_real_pass
        project_domain_name: Default
        project_name: shiftstack
        project_id: 5ad951d3776b46b3a6952aea86c9ad23
        user_domain_name: Default
        username: shiftstack_user
    cacert: /etc/pki/ca-trust/source/anchors/undercloud-cacert.pem
    identity_api_version: '3'
    region_name: regionOne

```

2. Configure the "shiftstack" cloud in the install-config.yaml:
```
platform:
  openstack:
    cloud:            "shiftstack"
    externalNetwork:  "nova"
    region:           "regionOne"
    computeFlavor:    "m4.xlarge"
    lbFloatingIP:     "10.46.44.161"
    ingressFloatingIP:     "10.46.44.182"
    externalDNS:      ["10.46.0.31"]
```

3. Run the 'openshift-install destroy bootstrap':
```
$ openshift-install destroy bootstrap --dir ostest --log-level debug
DEBUG OpenShift Installer 4.11.0-0.nightly-2022-11-18-172834
DEBUG Built from commit 0c4e73175c1aaa2140fb360ce8ff44a4b9dd669f
```
...
```

```

But OCP-installer fails to find the shiftstack cloud

The installer looks at the cloud.yaml finding the correct cloud name

* "openshift-install create cluster" manages to find the shiftstack cloud in the same environment.

* A similar issue, where "openshift-install create the cluster" failed to find a cloud defined in clouds.yaml in the current directory, fixed by https://bugzilla.redhat.com/show_bug.cgi?id=2064693.

Set the OS_CLIENT_CONFIG_FILE environment variable before executing the openshift-install:
```
$ pwd
/home/stack
$ export OS_CLIENT_CONFIG_FILE=/home/stack/clouds.yaml
$ openshift-install destroy bootstrap --dir ostest --log-level debug
DEBUG Destroy complete! Resources: 0 destroyed.
INFO Time elapsed: 3s
