Bonjour,
Today I activated a https://fuga.cloud (in anticipation for @pilou’s preliminary work supporting this OpenStack provider). My credit card was blocked but support@fuga.cloud replied quickly to my request and unblocked it.
As a first step I went to the team credentials page, created new credentials, copy/pasted the password, downloaded the openrc.sh file, replaced the password in the file and then:
$ source openrc.sh
$ openstack image list
