There are quite a few devops tools out there, i like saltstack and thanks to the openstack backend of zenithmedia, you can spin up instances with salt cloud!
You need to have salt, libcloud and salt-cloud installed, i am running these versions.
jsb@dev:/etc/salt$ salt-cloud --versions-report Salt: 2014.1.0-4765-gcbe7c7e Python: 2.7.3 (default, Feb 27 2014, 19:58:35) Jinja2: 2.6[ M2Crypto: 0.21.1 msgpack-python: 0.1.10 msgpack-pure: Not Installed pycrypto: 2.4.1 PyYAML: 3.10 PyZMQ: 13.0.0 ZMQ: 3.2.2 Apache Libcloud: 0.14.1
Check the official doc if you need setup instruction for salt and salt-cloud.
Once that’s done, you need to setup a provider. I created the following YAML file.
zenithmedia: identity_url: https://auth.zenithmedia.io/v2.0/tokens compute_name: nova compute_region: THE-REGION# service_type: compute tenant: 'THE-TENANT#' user: 'email@example.com#' password: S3cr37Pa55w0rd# provider: openstack networks: - fixed: - NETWORK-UUDI#
Everything that’s wrapped in “#” needs to be configured for your account, here is how to get the information. First, get some command line tools:
sudo pip install python-novaclient.
Once that’s done, go in the manager, in OpenStack Horizon, under Access & Security and finally under API Access. Download the OpenStack RC file. Save it on your box, source it and enter your password. It’s safe it comes from zenithmedia.
source /home/jsb/openstackrc Please enter your OpenStack Password:
Now we are ready to gather the information to complete de provider setup:
- THE-REGION#: run “nova endpoints”. In the nova table you will find the region, mine looks like “BHS-1”
- THE-TENANT#: run “nova credentials”, at the end of the table, you should see “name”: “00000000” where 000000 is a bunch of number. This can also be seen in the manager, under current project. Make sure this is between quotes in your config file or it will not work.
- NETWORK-UUDI#: run “nova network-list” and grab what’s in the id column, that will be your static network. In my case, there is only one and it’s labelled “Ext-Net”.
Once that’s done, the only thing left is to create vm image profiles. Im using these:
cat cloud.profiles.d/zenithmedia.conf high-cpu: provider: zenithmedia size: pci2.d.c1 deploy: False high-mem: provider: zenithmedia size: pci2.d.r1 deploy: False ubuntu-lts: image: Ubuntu 12.04 extends: high-cpu
You can run nova flavor-list to see what size are available and nova image-list for the OS. In both case, the configuration is expecting what’s in the Name column.
Once you are all set, spin up a new instance:
salt-cloud -p #the-cloud-profile-you-chose# #the-instance-name#
Happy automated deployment folks!
