Although Juju doesn't have baked-in knowledge of your OpenStack cloud, it does know how such clouds work in general. We just need to provide some information to add it to the list of known clouds.
Using the Juju
add-cloud command, it is easy to add your OpenStack clouds to
Juju's list of known clouds. The command is interactive, and will ask for
a name,endpoint,authorisation method(s) and regions to use. A sample session
is shown below.
...will enter the interactive mode. Enter the desired values to continue.
Cloud Types maas manual openstack vsphere Select cloud type: openstack Enter a name for your openstack cloud: devstack Enter the API endpoint url for the cloud: https://openstack.example.com:35574/v3.0/ Auth Types access-key userpass Select one or more auth types separated by commas: access-key,userpass Enter region name: dev1 Enter the API endpoint url for the region: https://openstack-dev.example.com:35574/v3.0/ Enter another region? (Y/n): n Cloud "devstack" successfully added You may bootstrap with 'juju bootstrap homestack'
Note that it is possible to choose more than one authorisation method - just separate the values with commas.
Once the cloud has been added, it will appear on the list of known clouds
output by the
juju clouds command. Note that the cloud name will be
highlighted to indicate that it is a locally added cloud.
It is also possible to define OpenStack clouds in a YAML formatted configuration file and register them with Juju. Please see the documentation for manually adding Openstack clouds for details.
If you source a novarc file for OpenStack, or use the default environmental variables for accessing this cloud, you can simply get Juju to scan for the credentials and add them.
Run the command...
Juju will search known locations, including environment variables, for credential information and present you with a set of choices for storing them. Simply follow the prompts.
For other methods of adding credentials, please see the specific credentials documentation.
The above steps are all you need to use most OpenStack clouds which are configured for general use. If this is your own cloud, you will also need to additionally provide stream information so that the cloud can fetch the relevant images for Juju to use. This is covered in the section on private clouds.
