As I mentioned earlier in Moving to OpenStackClient CLI I came across several differences in reconciling the legacy CLI tools.

I have also come across very inconsistent messaging. Here is a simple example.

In nova

$ nova list
ERROR (CommandError): You must provide an auth url via either --os-auth-url or env[OS_AUTH_URL] or specify an auth_system which defines a default url with --os-auth-system or env[OS_AUTH_SYSTEM]

In openstack

$ openstack service list
ERROR: openstack Authorization Failed: Cannot authenticate without an auth_url

$ openstack keypair list
ERROR: openstack Authentication requires 'auth_url', which should be specified in 'HTTPClient'

$ openstack catalog list
ERROR: openstack 'NoneType' object has no attribute 'auth'

$ openstack volume list
ERROR: openstack unsupported operand type(s) for +: 'NoneType' and 'str'

All three errors are effectively the same. That is I have not setup environment variables (OS_PROJECT_NAME, OS_AUTH_URL, OS_USERNAME, OS_PASSWORD) or passed all correctly as arguments.

In delving to the openstackclient source code specifically auth.py#147 I see another message “Set an authentication URL, with –os-auth-url, OS_AUTH_URL or auth.auth_url”. api.auth is also referenced in the Authentication Documentation as the place to start.

Time to delve in the code to see what I can find out.

cd
git clone git://git.openstack.org/openstack/python-openstackclient
cd python-openstackclient
python tools/install_venv.py
source .venv/bin/activate
# Don't need sudo for local environment
which openstack

After setting OS_USERNAME, OS_PASSWORD, and OS_PROJECT NAME (and not setting OS_AUTH_URL in my test) I run the following.

$ openstack image list
WARNING: openstackclient.shell Possible error authenticating: Missing parameter(s):
Set an authentication URL, with --os-auth-url, OS_AUTH_URL or auth.auth_url

ERROR: openstack Missing parameter(s):
Set an authentication URL, with --os-auth-url, OS_AUTH_URL or auth.auth_url

This matches what I saw in the code, so it’s the installed version that is older code. While user, service and keypair lists returns the same message volume and catalog still do not.

(.venv)rbradfor@octogon:~/python-openstackclient$ openstack volume list
