CLI tools for managing clouds, based on libcloud
lctools is a set of command-line utilities to control various clouds. It uses libcloud for cloud related stuff so should support as much cloud providers as libcloud does.


sudo python install

Getting started

We will use GoGrid as example.

First, create config file: ~/.lcrc with the following content:

driver = gogrid
access_id = your_key_id
secret_key = your_password

It is self-explanatory.

When you're done with the configuration file, you can start managing your servers. To list the available image, fire up lc-image-list command in your shell:

lc-image-list|grep -i centos
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)

Now, to get a list of available node sizes, do:

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)

So now you know ids of the images and available sizes, you can use them to create a new node like that:

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

It will create a centos node (id = 64) of size 1GB (id = '1GB') with name 'mynewnode'.

Now, to get a list of nodes, use:

100xxx mynode1 173.204.xx.yy Running
100xxx mynode2 173.204.xx.zz Running

When you're done with the node, you can remove it:

lc-node-do -i node_id destroy

where node_id is an id of the node you want to destroy. If you want to reboot node, just pass 'reboot' argument to this command instead of 'destroy'.
