Add base devstack plugins support
Add support for installing nova powervm through the devstack plugins infrastructure. This allows you to simply enable the plugin in a devstack localrc, provide any non-default config, and run stack.sh to configure/install it. - Added plugin files - Added README and example config - Added bashate to tox test environments for scripts Change-Id: I3dfed189e60b0aa63fc9029e3f56f2d8b7785bd3

========================
|
||||
Installing with Devstack
|
||||
========================
|
||||
|
||||
1. Download DevStack::
|
||||
|
||||
$ git clone https://git.openstack.org/openstack-dev/devstack /opt/stack/devstack
|
||||
|
||||
2. Modify DevStack's local.conf to pull in this project by adding::
|
||||
|
||||
[[local|localrc]]
|
||||
enable_plugin nova-powervm http://git.openstack.org/openstack/nova-powervm
|
||||
|
||||
2a. See the file "local.conf.example" in nova-powervm/devstack for reference
|
||||
on using this driver with the corresponding networking-powervm and
|
||||
ceilometer-powervm drivers. Following the example file will enable all
|
||||
three plugins, resulting an all-in-one powervm devstack node.
|
||||
|
||||
3. See nova-powervm/doc/source/devref/usage.rst, review the configuration options,
|
||||
then configure the installation in local.conf as needed for your environment.
|
||||
Besides DISK_DRIVER, the default config will be sufficient for most installs. ::
|
||||
|
||||
[[local|localrc]]
|
||||
...
|
||||
DISK_DRIVER =
|
||||
VOL_GRP_NAME =
|
||||
CLUSTER_NAME =
|
||||
|
||||
[[post-config|$NOVA_CONF]]
|
||||
[powervm]
|
||||
...
|
||||
|
||||
|
||||
4. Run ``stack.sh`` from devstack::
|
||||
|
||||
$ cd /opt/stack/devstack
|
||||
$ ./stack.sh
