Configuration
|
|
=============
|
|
|
|
Copy the sample configuration file ``config.yaml.sample`` to
|
|
``config.yaml`` and adjust the file accordingly.
|
|
|
|

To increase the number of compute nodes add more addresses to the
|
|
``compute`` list.

Clock synchronization (NTP)
|
|
---------------------------
|
|
|
|
Accurate clocks on every node are very important. Default is the the
|
|
usage of the `NTP Pool Project <http://www.pool.ntp.org/en/use.html>`__.
|
|
|
|
::
|
|
|
|
ntp:
|
|
- 0.pool.ntp.org
|
|
- 1.pool.ntp.org
|
|
- 2.pool.ntp.org
|
|
- 3.pool.ntp.org
|
|
|
|
Resources
|
|
---------
|
|
|
|
Default resources defined in ``~/.vagrant.d/Vagrantfile`` or the
|
|
``Vagrantfile`` provided by the base box will be overwritten. Resources
|
|
assigned to the controller node will be multiplied by two and additional
|
|
block storage devices will be attached to the controller and NFS nodes.
|
|
|
|
::
|
|
|
|
resources:
|
|
memory: 4096
|
|
vcpus: 2
|
|
storage: 65536
|
|
|
|
Development version
|
|
-------------------
|
|
|
|
To use the development version (``master``) of Packstack set
|
|
``development: true``.
|
|
|
|
Vagrant base box
|
|
----------------
|
|
|
|
In theory (not tested) it is possible to use RHEL or Fedora instead of
|
|
CentOS. Default is ``b1-systems/centos-packstack``, a customized
|
|
Vagrantbox based on
|
|
`boxcutter/centos70 <https://github.com/box-cutter/centos-vm>`__. The
|
|
sources of the used `Packer <https://packer.io/>`__ template is
|
|
available on `Github <https://github.com/b1-systems/packer-templates>`__
|
|
and the box iself on
|
|
`Atlas <https://atlas.hashicorp.com/b1-systems/centos-packstack>`__.
|
|
|
|
To change the used Vagrant base box modify the value of ``box``. A list
|
|
of public available Vagrant boxes is available on
|
|
`Atlas <https://atlas.hashicorp.com/>`__.
|
|
|
|
Depending on the used base box you have to set the used storage
|
|
controller (normally ``IDE Controller`` or ``SATA Controller``). The
|
|
storage controller of the base box must support at least three ports.
|
|
|
|
Storage backend
|
|
---------------
|
|
|
|
At the moment NFS is the only supported storage backend. Support for
|
|
Ceph will be added in the future (at the moment Ceph is not supported as
|
|
a storage backend in Packstack).
|
|
|
|
Timezone
|
|
--------
|
|
|
|
At the moment it is not possible to configure the timezone with
|
|
Packstack.
|
|
|
|
Caching / Proxying
|
|
------------------
|
|
|
|
To speed up the provisioning the Vagrant plugin
|
|
`vagrant-proxyconf <https://github.com/tmatilai/vagrant-proxyconf/>`__
|
|
configures a HTTP proxy to be used by ``yum``.
|
|
|
|
::
|
|
|
|
$ vagrant plugin install vagrant-proxyconf
|
|
|
|
When the plugin is installed caching/proxying is not enabled by default. To
|
|
enable caching/proxying set ``use`` to ``true``.
|
|
|
|
``address`` has to point to an existing HTTP proxy server (e.g.
|
|
``http://proxy.company.site:3128``).
|
|
|
|
::
|
|
|
|
proxy:
|
|
use: true
|
|
install: false
|
|
address: 'http://proxy.company.site:3128'
|
|
|
|
To install the HTTP proxy `Squid <http://www.squid-cache.org/>`__ on the
|
|
controller node set ``install`` to ``true``.
|
|
|
|
To use the local proxy set ``use`` to ``true``. ``address`` has not to
|
|
be set when installing Squid on the controller node. ``address`` will be
|
|
overwritten when installing Squid as local HTTP proxy.
|
|
|
|
::
|
|
|
|
proxy:
|
|
install: true
|
|
use: true
|
