TryStack is OpenStack Sandbox

Leave a reply

OpenStack announced their sandbox called TryStack.
The saying goes like this “The Easiest Way To Try Out OpenStack”.

I manage to get an account via Facebook and testdrive TryStack.
The username and password were posted at Messages->Others. 🙂
The steps to launch an instance using TryStack
1. Creating Keypairs.
Name your keypair, mine is trystack. It will prompt to download.
Save the file will be used for SSH later.
Screenshot is here.

2. Allowing ports SSH and HTTP. In this case open to all networks for port 22 and 80.
Screenshot is here.

3. Click on Images, and put some server name, instance type, and user-data.
Screenshot is here.

4. Success page. Screenshot here.

5. Now try to SSH to the instance using the keypair downloaded.

chmod 600 ~/trystack/trystack.pem
ssh -i ~/trystack/trystack.pem ubuntu@<IP-ADDRESS> -v

Very nice and cool..! Don’t you think? 🙂

Here’s a good tutorial also using nova client from Sagar.

LittleChef: playing with Chef recipes

Leave a reply

For small number of servers and push deployment, I show how to run LittleChef here:

Using RVM for Ruby needed for Chef’s knife later.

ubuntu@testbox:~/littlechef$ rvm use 1.9.2

Using virtrualenv for Python, so as not to clutter environment’s Python installation.
Genenerate metadata.json for Chef recipes.

ubuntu@testbox:~/littlechef$ workon lchef
ubuntu@testbox:~/littlechef$ cd kitchen/cookbooks
(lchef)ubuntu@testbox:~/littlechef/kitchen/cookbooks$ knife cookbook metadata -a  -o ./

List nodes using LittleChef: 

(lchef)ubuntu@testbox:~/littlechef/$ fix list_nodes
ec2-xx-xx-xxx-xxx.compute-1.amazonaws.com
  Roles: 
  Recipes: alestic_ppa
  Node attributes:

server2
  Roles: 
  Recipes: mdadm, memcached
  Node attributes:
    mdadm: {'DEVICE': '/dev/sdj'}
    memcached: {'memory': '512'}

List of files on my kichen directory:

 
(lchef)ubuntu@testbox:~/littlechef/kitchen$ ls
auth.cfg  cookbooks  data_bags  nodes  roles  site-cookbooks

(lchef)ubuntu@testbox:~/littlechef/kitchen$ ls cookbooks/
alestic_ppa  apt  graylog2  java  java_sun  logrotate  mdadm  memcached  mongodb  mongodbx  nginx  quick_start  README  runit  xfs

Ok, let’s run the nginx installation using LittleChef to lucid32 server.
For simplicity, /etc/hosts file contains the IP mapping of lucid32 server.

(lchef)ubuntu@testbox:~/littlechef/kitchen$ fix node:lucid32 recipe:nginx

== Applying recipe 'nginx' on node lucid32 ==
Saving node configuration to nodes/lucid32.json...
Synchronizing node, cookbooks, roles and data bags...

SUCCESS: Node correctly configured

Done.

Now to check for the running Nginx server: 

(lchef)ubuntu@testbox:~/littlechef/kitchen$ fix node:lucid32 ssh:"sudo netstat -lp | grep nginx "

Executing the command 'sudo netstat -lp | grep nginx ' on the node lucid32...

Done.
