install(*args, **kwargs)¶

Install nova compute

Parameters:

my_ip – (String) IP address of this host
rabbit_hosts – RabbitMQ HA cluster host:port pairs. (list value) e.g. CONTROLLER1,CONTROLLER2
rabbit_user – The RabbitMQ userid. (string value) e.g. openstack
rabbit_pass – The RabbitMQ password. (string value)
auth_uri – (String) Complete public Identity API endpoint. e.g. http://CONTROLLER_VIP:5000
auth_url – (String) Authentication endpoint e.g. http://CONTROLLER_VIP:35357
nova_pass – passowrd of nova user
novncproxy_base_url – (String) Public address of noVNC VNC console proxy. The VNC proxy is an OpenStack component that enables compute service users to access their instances through VNC clients. noVNC provides VNC support through a websocket-based client. This option sets the public base URL to which client systems will connect. noVNC clients can use this address to connect to the noVNC instance and, by extension, the VNC sessions. Possible values: * A URL Services which consume this: * nova-compute Related options: * novncproxy_host * novncproxy_port e.g. http://CONTROLLER_VIP:6080/vnc_auto.html
glance_api_servers – (List) A list of the glance api servers endpoints available to nova. These should be fully qualified urls of the form scheme://hostname:port[/path] e.g. http://CONTROLLER_VIP:9292
neutron_endpoint – neutron endpoint e.g. http://CONTROLLER_VIP:9696
neutron_pass – the password of neutron user
rbd_secret_uuid – ceph rbd secret for nova libvirt , generated by uuidgen
memcached_servers – A list of memcached server(s) to use for caching. (list value) e.g. CONTROLLER1:11211,CONTROLLER2:11211

Returns:

None
