Configuration

Copy the sample configuration file config.yaml.sample to config.yaml and adjust the file accordingly.

Networking

Bridges

bridge_internal: tap0
bridge_external: tap1

Addresses

netmask_internal: 255.255.0.0
address:
  controller: 10.100.50.10
  nfs: 10.100.50.41
  network: 10.100.50.30
  shared: 10.100.50.50
  storage: 10.100.50.40
  compute:
  - 10.100.50.20
  - 10.100.50.21

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

L2 agent

network_agent: openvswitch

Tenant networks

network_type: gre

Clock synchronization (NTP)

Accurate clocks on every node are very important. Default is the the usage of the NTP Pool Project.

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. The sources of the used Packer template is available on Github and on the Vagrantcloud.

To change the used Vagrant base box modify the value of box. A list of public available Vagrant boxes is available at https://vagrantcloud.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

To speed up the provisioning the Vagrant plugin vagrant-cachier can be used.

$ vagrant plugin install vagrant-cachier

When the plugin is installed caching is enabled by default. To explicitly disable caching when the plugin is installed set use_cache: false.
