# Overview
|
|
|
|
*This charm is in ALPHA state, currently in active development.*
|
|
|
|
*Developers can be reached on freenode channel #openstack-charms.*
|
|
|
|
The nova-compute-proxy charm deploys OpenStack Nova Compute to a
|
|
pre-existing rpm-based Power8 PowerKVM or s390x z/KVM machine,
|
|
where the remainder of the Ubuntu OpenStack control plane and storage
|
|
applications are deployed to machines via MAAS.
|
|
|
|
# Usage
|
|
|
|
To deploy a nova-compute-proxy service, have the following prepared in
|
|
advance:
|
|
|
|
* PowerKVM or z/KVM machine(s) manually provisioned, booted, accessible from
|
|
the control plane units, with network interfaces and storage ready to use.
|
|
* An ssh key that the charm can use to remotely execute installation and
|
|
configuration operations.
|
|
* Yum repository/repositories or .iso file(s) which contain the appropriate
|
|
IBM OpenStack RPMs. If using .iso file(s), they must be loop-mounted
|
|
on the compute node host.
|
|
* Password-less sudo for the specified user configured on the compute node.
|
|
|
|
Once you have this setup you must configure the charm as follow:
|
|
|
|
* Apply the following charm config:
|
|
* remote-user: username used to access and configure the power node.
|
|
* remote-repos: Yum repository url(s) or file url(s)
|
|
* remote-hosts: IP address of power node
|
|
* remote-key: Private key string to use for access
|
|
* Example:
|
|
```
|
|
remote-user: youruser
|
|
remote-repos: file:///tmp/openstack-iso/openstack,file:///tmp/other-iso/repofs
|
|
remote-key: |
