Use Juju on top of OpenStack to deploy apps

I'd like to create a new cloud in JUJU for OPENSTACK and use that to deploy the Apps on my Instances. In my lab, MAAS, JUJU and OPENSTACK are correctly installed and the instancse works fine. I've followed this guide but at the end during the bootstrap I receive this error:

ERROR authentication failed.: authentication failed

these commands have being launched on MAAS server, where I've installed juju.

    You will need to add credentials for this cloud (`juju add-credential openstack-cloud`)
before creating a controller (`juju bootstrap openstack-cloud`).

Solution 1:

I've resolved that filling the credential in this way

$: juju add-credential openstack-cloud
 Enter credential name: openstack_credential
 Using auth-type "userpass".
 Enter username: admin
 Enter password: 
 Enter tenant-name (optional): u1804Pro 
 Enter tenant-id (optional): 
 Enter version (optional): 
 Enter domain-name (optional):
 Enter project-domain-name (optional): u1804Dom 
 Enter user-domain-name (optional): u1804Dom
 Credential "openstack-credential" added locally for cloud "openstack-cloud".

where:

  • u1804Dom is my new domain defined in Openstack
  • u1804Pro my new project defined in Openstack

now I could to lauch the bootstrap withour error

$:juju bootstrap openstack-cloud --bootstrap-series=bionic --config network="Private Network IPv4"  --config external-network="Floating Network IPv4" --config use-floating-ip=true --metadata-source ~/simplestreams/images --debug
