Test repo for cloud computing

NCI has a git repository for puppet - repos.nci.org.au

Directory structure

Puppet will load the file manifests/site.pp when performing a build. This file in turn loads modules from that directory to install each program. In the NCI repository a private directory is used to store rsa keys, this is only accessable to members of a project group.

manifests
    site.pp
modules
    module-name
            files
            templates
            manifests
private

Accessing

Use nova command (python-novaclient) to access the NCI cloud.

You can query the capabilities with list commands

# List images (ie. Ubuntu, Centos &c)
$ nova image-list

# List available ssh public keys
$ nova keypair-list

# List VM sizes (memory, number of cpus)
$ nova flavor-list

# List access types (ports open by default, e.g. ssh, http)
$ nova secgroup-list

# Boot an instance
$ nova boot NAME --image IMAGE --key KEY --flavor FLAVOUR --security_groups SECGROUP --user-data USERDATA

User data is a shell script to be run once the VM has booted. It is used to run puppet.

IP addresses must be assigned separately

$ nova floating-ip-list
$ nova add-floating-ip NAME IP

The melbourne directory of this repo includes scripts to start up a Ubuntu image on the Melbourne Nectar cloud. It requires openstack credentials to have been loaded into the environment, you will need to download this from the Nectar cloud website.

cloud-test's Issues

Separate out common.pp

All of the rose/cylc stuff is currently bundled up in a common file, needs to be extracted into modules for each

Create files in /etc/profile.d for prepend-path

Files in /etc/profile.d are autoloaded by bash on login, it seems like it would be a good idea to use these to edit paths &c since we can use puppet's file creation rather than managing /etc/bashrc manually.
