Vagrant node definitions for GOV.UK
You will need access to the repos:
govuk-puppetfor configuration management of the nodes
govuk-provisioningfor node definitions
The above repos should be cloned in parallel to this one. Either
gds/development:install.sh can do this for you.
It is recommended that you use Vagrant > 1.4 from a binary/system install.
alphagov/gds-boxen can set this up for you.
You need only bring up the subset of nodes that you're working on. For example, to bring up a frontend and backend:
vagrant up frontend-1.frontend backend-1.backend
Vagrant will run the Puppet provisioner against the node when it boots up.
Nodes should look almost identical to that of our real
production/staging/preview environments, including network addresses. To
access a node's services like HTTP/HTTPS you can point your
hosts file to
the host-only IP address (eth1).
Physical attributes like
num_cores will be ignored because
they don't scale appropriately to local VMs, but can still be customised as
Node definitions can be overridden with a
nodes.local.yaml file in the
vagrant-govuk directory. This is merged on top of all other node
definitions. The following keys are currently available for customisation:
box_distUbuntu distribution. Currently "precise".
box_versionInternal version number of the GDS basebox.
memoryAmount of RAM. Default is "384".
ipIP address for hostonly networking. Currently all subnets are /16.
className of the Puppet class/role.
For example to increase the amount of RAM on a PuppetMaster:
--- puppetmaster-1.management: memory: 768
Some errors that you might encounter..
NFS failed mounts
[frontend-1.frontend] Mounting NFS shared folders... Mounting NFS shared folders failed. This is most often caused by the NFS client software not being installed on the guest machine. Please verify that the NFS client software is properly installed, and consult any resources specific to the linux distro you're using for more information on how to do this.
This seems to be caused by a combination of OSX, VirtualBox, and Cisco
AnyConnect. Try temporarily disconnecting from the VPN when bringing up a
new node. You can also set
VAGRANT_GOVUK_NFS=no as an environment variable to disable the use of NFS. This is less perfomant but fine for checking puppet runs.
