Details
Juju needs to know how to connect to clouds. A cloud definition describes a cloud’s endpoints and authentication requirements. Each definition is stored and accessed later as <cloud name>.
If you are accessing a public cloud, running add-cloud is unlikely to be necessary. Juju already contains definitions for the public cloud providers it supports.
add-cloud operates in two modes:
juju add-cloud
juju add-cloud <cloud name> <cloud definition file>
When invoked without arguments, add-cloud begins an interactive session designed for working with private clouds. The session will enable you to instruct Juju how to connect to your private cloud.
A cloud definition can be provided in a file either as an option -f or as a positional argument:
juju add-cloud mycloud ~/mycloud.yaml
juju add-cloud mycloud -f ~/mycloud.yaml
When <cloud definition file> is provided with <cloud name>, Juju will validate the content of the file and add this cloud to this client as well as upload it to a controller.
Use --controller option to upload a cloud to a controller.
Use --client option to add cloud to the current client.
A cloud definition file has the following YAML format:
clouds: # mandatory
mycloud: # <cloud name> argument
type: openstack # <cloud type>, see below
auth-types: [ userpass ]
regions:
london:
endpoint: https://london.mycloud.com:35574/v3.0/
Cloud types for private clouds:
- lxd
- maas
- manual
- openstack
- vsphere
Cloud types for public clouds:
- azure
- ec2
- gce
- oci
When a running controller is updated, the credential for the cloud is also uploaded. As with the cloud, the credential needs to have been added to the current client, use add-credential to do that. If there’s only one credential for the cloud it will be uploaded to the controller automatically by add-cloud command. However, if the cloud has multiple credentials on this client you can specify which to upload with the --credential option.
When adding clouds to a controller, some clouds are whitelisted and can be easily added:
- controller cloud type “kubernetes” supports [lxd maas openstack]
- controller cloud type “lxd” supports [lxd maas openstack]
- controller cloud type “maas” supports [maas openstack]
- controller cloud type “openstack” supports [openstack]
Other cloud combinations can only be force added as the user must consider network routability, etc - concerns that are outside of scope of Juju. When forced addition is desired, use --force.
