Docker Containers for Humans™

⚠️ WARNING This is a very early alpha release of cargo. APIs are subject to change. All development for this project is being done in the open. Contributions and critiques are totally welcome, but please at least announce and discuss your plans via an issue before submitting a pull request so we can all collectively create something beautiful!

Examples

inspect currently running local containers

>>> from cargo import Dock
>>> d = Dock()
>>> d.containers
[<Container [9a7a6a52171d]>, <Container [b575c9ece1b9]>, <Container [b225c9398c4b]>]

Alternatively, you can get the same result with cargo.ps:

>>> import cargo
>>> cargo.ps()
[<Container [9a7a6a52171d]>, <Container [b575c9ece1b9]>, <Container [b225c9398c4b]>]

get dock metadata

>>> d 
<Dock [http://localhost:4243] (1.3)>
>>> d.info
{u'NFd': 28, u'MemoryLimit': True, u'NGoroutines': 36, u'Images': 112, u'Debug': False, u'Containers': 189}
>>> d.memory_limit
True

inspect command string running in container

>>> container = d.containers[0]
>>> container.command
u'python -m SimpleHTTPServer'

inspect forwarded container ports

In this example, we're forwarding port 49155 locally to port 8000 within the container.

>>> container = d.containers[0]
>>> container.ports
[(49155, 8000)]

inspect container logs

In this example we are running python -m SimpleHTTPServer to fire up a basic HTTP server on port 8000. We use container.ports to grab out the locally forwarded port, issue an HTTP GET using python requests, and then inspect the subsequent container logs, which now contain an apache logs entry for our GET request, ✨ as if by magic! ✨

>>> import cargo
>>> import requests
>>> container = cargo.ps()[0]
>>> container
<Container [9a7a6a52171d]>
>>> container.command
u'python -m SimpleHTTPServer'
>>> container.logs
u''
>>> requests.get('http://localhost:%s' % (container.ports[0][0]))
<Response [200]>
>>> container.logs
u'172.16.42.1 - - [11/Aug/2013 12:49:56] "GET / HTTP/1.1" 200 -\n'
