devstack-vagrant
|
|
================
|
|
|
|
This is an attempt to build an easy to use tool to bring up a 2 node
|
|
devstack environment for local testing using Vagrant + Puppet.
|
|
|
|
It is *almost* fully generic, but still hard codes a few things about
|
|
my environment for lack of a way to figure out how to do this
|
|
completely generically (puppet templates currently hate me under
|
|
vagrant).
|
|
|
|
This will build a vagrant cluster that is L2 bridged to the interface
|
|
that you specify in ``config.yaml``. All devstack guests (2nd
|
|
level) will also be L2 bridged to that network as well. That means
|
|
that once you bring up this environment you will be able to ssh
|
|
stack@api (or whatever your hostname is) from any machines on your
|
|
network.
|
|
|
|
Vagrant Setup
|
|
------------------------
|
|
|
|
Install vagrant & virtual box
|
|
|
|
Configure a base ``~/.vagrant.d/Vagrantfile`` to set your VM size. If you
|
|
have enough horsepower you should make the file something like:
|
|
|
|
VAGRANTFILE_API_VERSION = "2"
|
|
|
|
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
|
|
config.vm.provider :virtualbox do |vb|
|
|
|
|
# Use VBoxManage to customize the VM. For example to change memory:
|
|
vb.customize ["modifyvm", :id, "--memory", "8192"]
|
|
vb.customize ["modifyvm", :id, "--cpus", "4"]
|
|
end
|
|
end
|
|
|
|
You can probably get away with less cpus, and 4096 MB of memory, but
|
|
the above is recommended size.
|
|
|
|
If the used hostnames in the ``config.yaml`` file (variable ``hostname_manager``
|
|
and ``hostname_compute``) are not resolvable you have to install the
|
|
``vagrant-hostmanager`` plugin (``vagrant plugin install vagrant-hostmanager``).
|
|
|
|
If the nodes are still not able to communicate to each other even after
|
|
installing the ``vagrant-hostnamanger`` plugin (for example you get errors about
|
|
the compute node not being able to communicate to *cinder c-api* during the
|
|
*vagrant up* phase), set the variable ``use_ip_resolver`` in the ``config.yaml``
|
|
file to ``true``, in order to obtain the correct nodes ip.
|
|
|
|
|
|
Local Setup
|
|
--------------------
|
|
Copy ``config.yaml.sample`` to ``config.yaml`` and provide the
|
|
hostnames you want, and password, and sshkey for
|
|
the stack user.
|
|
|
|
Then run vagrant up.
|
|
|
|
On a 32 GB Ram, 4 core i7 haswell, on an SSD, with Fios, this takes
|
|
25 - 30 minutes. So it's not quick. However it is repeatable.
|
|
|
|
If you want to speed-up the process, install the
|
|
[vagrant-cachier](https://github.com/fgrehm/vagrant-cachier) plugin in order
|
|
to let vagrant cache files, such as apt packages, with:
|
|
|
|
vagrant plugin install vagrant-cachier
|
|
|
|
|
|
What you should get
|
|
-----------------------------------
|
|
A 2 node devstack that includes cirros mini cloud image populated in glance.
|
|
You can get other images population such as fedora 20, ubuntu 12.04,
|
|
and ubuntu 14.04, just with a small addtion to ``extra_images`` part
|
|
in ``config.yaml.sample``.
|
|
|
|
Default security group with ssh and ping opened up.
|
|
|
|
Installation of the stack user ssh key as the default keypair.
|
|
|
|
Enable additional services
|
|
------------------------
|
|
The devstack environment created by this `Vagrantfile` includes just the basic
|
|
services to get started with OpenStack. If you want to try more services, you
|
|
can enable them on the manager node through the ``config.yaml`` file.
|
|
|
|
For example if you want to enable
|
|
[Swift](https://docs.openstack.org/developer/swift), you can add the
|
|
following line to your ``config.yaml``:
|
|
|
|
manager_extra_services: s-proxy s-object s-container s-account
