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
).
Local Setup
Copy config.yaml.sample
to config.yaml
and provide the
hostnames you want, and password hash (not 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 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.
