Python Library for Dockercloud

# python-docker-cloud

Python library for Docker Cloud

## Installation

In order to install the Docker Cloud Python library, you can use pip install:

pip install python-dockercloud

It will install a Python module called dockercloud which you can use to interface with the API.

## Authorization

The authentication can be configured in the following ways:

• Manually set it in your Python initialization code:

  import dockercloud dockercloud.user = “username” dockercloud.apikey = “apikey”

• Login with docker cli, and the library will read the configfile automatically:

  $ docker login

• Set the environment variables DOCKERCLOUD_USER and DOCKERCLOUD_APIKEY:

  export DOCKERCLOUD_USER=username export DOCKERCLOUD_APIKEY=apikey

## Optional parameters

You may set the reconnection interval (Integer, in seconds) using the variable DOCKERCLOUD_RECONNECTION_INTERVAL:

export DOCKERCLOUD_RECONNECTION_INTERVAL=240

Session uses a socket that may be closed by some peer. To prevent the “Read timed out” issue you should use this option.

Possible values:

• -1 (by default) means no reconnect (as usually it works)

• 0 means reconnect on each request

• any positive value means that the connection will be reopened if the time diff between last 2 requests is more than that value

## Namespace

To support teams and orgs, you can specify the namespace in the following ways:

• Set it in the Python code:

  import dockercloud dockercloud.namespace = “yourteam”

• Set it in the environment variable:

  export DOCKERCLOUD_NAMESPACE=yourteam

## Errors

Errors in the HTTP API will be returned with status codes in the 4xx and 5xx ranges.

The Python library will detect this status codes and raise ApiError exceptions with the error message, which should be handled by the calling application accordingly.

## Quick examples

### Services

>>> import dockercloud
>>> dockercloud.Service.list()
[<dockercloud.api.service.Service object at 0x10701ca90>, <dockercloud.api.service.Service      object at 0x10701ca91>]
>>> service = dockercloud.Service.fetch("fee900c6-97da-46b3-a21c-e2b50ed07015")
<dockercloud.api.service.Service object at 0x106c45c10>
>>> service.name
"my-python-app"
>>> service = dockercloud.Service.create(image="dockercloud/hello-world", name="my-new- app", target_num_containers=2)
>>> service.save()
True
>>> service.target_num_containers = 3
>>> service.save()
True
>>> service.stop()
True
>>> service.start()
True
>>> service.delete()
True

### Containers

>>> import dockercloud
>>> dockercloud.Container.list()
[<dockercloud.api.container.Container object at 0x10701ca90>, <dockercloud.api.container.Container object at 0x10701ca91>]
>>> container = dockercloud.Container.fetch("7d6696b7-fbaf-471d-8e6b-ce7052586c24")
<dockercloud.api.container.Container object at 0x10701ca90>
>>> container.public_dns = "my-web-app.example.com"
>>> container.save()
True
>>> container.stop()
True
>>> container.start()
True
>>> container.logs()
"2014-03-24 23:58:08,973 CRIT Supervisor running as root (no user in config     file) [...]"
>>> container.delete()
True
