+--------------------------------------+--------------+--------+

If OS_AUTH_URL uses the HTTPS protocol, you have to mount under /etc/ssl/cacerts.pem the file with the certificates used for the TLS validation.

$ docker run --rm -ti --env-file openstack.env \
    -v "/path/to/cacerts.pem:/etc/ssl/cacerts.pem:ro" \
    psmiraglia/openstackclients openstack image list

| ID                                   | Name         | Status |
+--------------------------------------+--------------+--------+
| ...                                  | ...          | active |
