The OpenStack Dashboard provides a Django based web interface for use by both administrators and users of an OpenStack Cloud.
It allows you to manage Nova, Glance, Cinder and Neutron resources within the cloud.
The OpenStack Dashboard is deployed and related to keystone:
juju deploy openstack-dashboard juju add-relation openstack-dashboard keystone
The dashboard will use keystone for user authentication and authorization and to interact with the catalog of services within the cloud.
The dashboard is accessible on:
At a minimum, the cloud must provide Glance and Nova services.
To fully secure your dashboard services, you can provide a SSL key and certificate for installation and configuration. These are provided as base64 encoded configuration options::
juju set openstack-dashboard ssl_key="$(base64 my.key)" \ ssl_cert="$(base64 my.cert)"
The service will be reconfigured to use the supplied information.
When more than one unit is deployed with the hacluster application the charm will bring up an HA active/active cluster.
There are two mutually exclusive high availability options: using virtual IP(s) or DNS. In both cases the hacluster subordinate charm is used to provide the Corosync and Pacemaker backend HA functionality.
Note: Regardless of which HA method has been chosen, the
secretoption should be set to ensure that the Django secret is consistent across all units.
If the charm is being deployed into a keystone v3 enabled environment then the charm needs to be related to a database to store session information. This is only supported for Mitaka or later.
Use with a Load Balancing Proxy
Instead of deploying with the hacluster charm for load balancing, its possible to also deploy the dashboard with load balancing proxy such as HAProxy:
juju deploy haproxy juju add-relation haproxy openstack-dashboard juju add-unit -n 2 openstack-dashboard
This option potentially provides better scale-out than using the charm in conjunction with the hacluster charm.
This charm supports providing a custom theme as documented in the themes configuration. In order to enable this capability the configuration options 'ubuntu-theme' and 'default-theme' must both be turned off and the option 'custom-theme' turned on.
Once the option is enabled a custom theme can be provided via a juju resource. The resource should be a .tgz file with the contents of your custom theme. If the file 'local_settings.py' is included it will be sourced.
juju attach-resource openstack-dashboard theme=theme.tgz
Repeating the attach-resource will update the theme and turning off the custom-theme option will return to the default.
Policy overrides is an advanced feature that allows an operator to override the default policy of an OpenStack service. The policies that the service supports, the defaults it implements in its code, and the defaults that a charm may include should all be clearly understood before proceeding.
Caution: It is possible to break the system (for tenants and other services) if policies are incorrectly applied to the service.
Policy statements are placed in a YAML file. This file (or files) is then placed into an appropriately-name directory (or directories) and (ZIP) compressed into a single file. This compressed file is then used as an application resource. Finally, the override is enabled via a Boolean charm option.
The directory names correspond to the OpenStack services that Horizon has policy override support for:
Important: The exact same overrides must also be implemented at the service level using the appropriate charm. See the Policy Overrides section of each charm's README.
For example, to provide overrides for Nova and Keystone, the compressed file should have a structure similar to the following (the YAML filenames are arbitrary):
\ compute - compute-override1.yaml | \ compute-override2.yaml | \ identity - identity-override1.yaml | identity-override2.yaml \ identity-override3.yaml
Here are the essential commands:
zip -r overrides.zip compute identity juju attach-resource openstack-dashboard policyd-override=overrides.zip juju config openstack-dashboard use-policyd-override=true
