lctools

lctools is a handy set of command-line utilities designed to help you manage different cloud services. It's built on libcloud, which means it can connect with a lot of cloud providers, just like libcloud does.

Installation Instructions

To get started, you'll need to install it. You can do this by running:

sudo python setup.py install

Setting Up with GoGrid

For our example, we'll use GoGrid. First, you need to create a configuration file named ~/.lcrc. Here's what you should include:

[default]

driver = gogrid

access_id = your_key_id

secret_key = your_password

This setup is pretty straightforward!

Managing Your Servers

Once your config file is ready, you're all set to start managing your servers. To see the available images, type the following command in your terminal:

lc-image-list|grep -i centos

You should see something like this:

• image CentOS 5.2 (32-bit) w/ RightScale (id = 62)


• image CentOS 5.2 (64-bit) w/ RightScale (id = 63)


• image CentOS 5.3 (32-bit) w/ None (id = 1531)


• image CentOS 5.3 (64-bit) w/ None (id = 1532)

Finding Node Sizes

If you want to check out the available node sizes, just run:

lc-sizes-list

• size 512MB (id=512MB, ram=512, disk=30 bandwidth=None)


• size 4GB (id=4GB, ram=4096, disk=240 bandwidth=None)


• size 2GB (id=2GB, ram=2048, disk=120 bandwidth=None)


• size 8GB (id=8GB, ram=8192, disk=480 bandwidth=None)


• size 1GB (id=1GB, ram=1024, disk=60 bandwidth=None)

Create a New Node

You now know the IDs of both images and sizes! To create a new node using this info:

lc-node-add -i 62 -s 1GB -n mynewnode

This command will spin up a CentOS node with ID '64', sized at '1GB', and named 'mynewnode'. Cool right?
