Using ShutIt and Docker to play with AWS (Part One)

I’m using ShutIt to play with AWS at the moment.

I can leverage the core libraries to easily build on top with my secret data and store in my source control system, and I’ll show how you can do this here.

Firstly, there’s a core aws library that takes care of installing the aws command line tool which is part of the ShutIt libraries:

Shutit AWS module

ShutIt AWS build script

It contains the ability to configure the AWS access token, but obviously we don’t want to store that in the core library.

The solution to this to create my own module which effectively inherits from that generic solution, adding my pems and configuring for access.

/space/git/shutit/shutit skeleton /my/git/path/ianmiellaws ianmiellaws my.domain
cd /my/git/path/ianmiellaws
mv /path/to/pems context/
cd /my/git/path/ianmiellaws/
vi configs/
vi ianmiellaws.py
./test.sh

The bits in bold were the bits edited in the above vi edit:

imiell@lp01728:/space/git/work/notes/aws/ianmiellaws$ cat ianmiellaws.py
from shutit_module import ShutItModule

class ianmiellaws(ShutItModule):

    def is_installed(self,shutit):        
        return False

    def build(self,shutit):
        shutit.send_host_file('t2.pem','context/pems/t2.pem')     
        return True


def module():
    return ianmiellaws(
        'my.domain.ianmiellaws.ianmiellaws', 1159697827.00,
        description='',
        maintainer=''
        depends=['shutit.tk.setup','shutit.tk.aws.aws']       
)

In the config file edit I put (replacing the stuff in caps with my details):

[my.domain.aws.aws]
access_key_id:MYKEYHERE
secret_access_key:MYSECRETACCESSKEYHERE
region:MYREGION
output:

Then build it:

/path/to/shutit build -m /path/to/shutit/library

Then run it:

docker run -t -i ianmiellaws /bin/bash

and you should be able to access your AWS services from wherever you have the container.

In the next posts I’ll show how to build on top of this to write a module to automatically provision an AWS instance and run a docker service on it.
