CoreOS is a new operating system ready for the cloud computing. In this guide, we will talk about how to install CoreOS on Rackspace Cloud. We talked about CoreOS in small details in a previous article. CoreOS is currently under active development. Rackspace Openstack cloud differs slightly from the generic Openstack, so there will be some difference with OpenStack instructions.

Does not work for Rackspace. As practically we are not everyday testing these things, our last tries were successful by a opening a ticket to Rackspace support to enable PV-GRUB. This was for other non CoreOS custom Linux Distro. The steps demands good grasp on UNIX. However, for CoreOS, these are not required.

CoreOS on Rackspace Cloud : Basics
We need to install Python for installing Supernova tool. Details was described on this article – OpenStack Cloud Tools Python Packages. Run these commands :
|
1 2 3 |
sudo pip install keyring sudo pip install rackspace-novaclient sudo pip install supernova |
Edit your config file :
|
1 |
vi ~/.supernova |
Store your username, API key and some other settings. From documentation of CoreOS, these will be like these :
|
1 2 3 4 5 6 7 8 9 10 11 |
[production] OS_AUTH_URL = https://identity.api.rackspacecloud.com/v2.0/ OS_USERNAME = your-username OS_PASSWORD = fd62afe2-4686-469f-9849-ceaa792c55a6 OS_TENANT_NAME = nova-production [development] OS_AUTH_URL = http://dev.nova.example.com:8774/v1.1/ OS_USERNAME = jsmith OS_PASSWORD = 40318069-6069-4d9f-836d-a46df17fc8d1 OS_TENANT_NAME = nova-development |
jsmith username is given for dev purpose as per with the documentation. Add RSA keypairs :
|
1 |
supernova production keypair-add --pub-key ~/.ssh/coreos.pub coreos-key |
Booting :
|
1 |
supernova production boot --image 430d35e0-1468-4007-b063-52ee1921b356 --flavor 2 My_CoreOS_Server --key-name coreos-key |
