Hi,
I am using the following cloud-config file:

[Global]
auth-url=https://auth.cloud.ovh.net/v3/
username=user-xxx
password=yyy
tenant-id=zzz
domain-name=default

the same credentials, options, I use to authenticate via the openstack terraform provider

...
        - name: cluster-autoscaler
          image: registry.k8s.io/autoscaling/cluster-autoscaler:v1.30.1
          imagePullPolicy: Always
          command:
            - ./cluster-autoscaler
            - --alsologtostderr
            - --cluster-name=cluster.local
            - --cloud-config=/config/cloud-config
            - --cloud-provider=magnum
            - --nodes=1:10:DefaultNodeGroup
            - --v=2
          volumeMounts:
            - name: cloud-config
              mountPath: /config
              readOnly: true
...

but I get the following error on boot:

If I inject OS_* env var:

...
          env:
            - name: OS_AUTH_URL
              valueFrom:
                secretKeyRef:
