dockerblade

Dockerblade makes it easy to interact with Docker containers by providing an API, inspired by Python's standard libraries (e.g., subprocess, os, and io) for executing commands and interacting with filesystems.

Installation

To install the latest release of dockerblade via pipenv or pip:

$ pipenv install dockerblade

Usage

To connect to a Docker daemon on the host machine and attach to a running container:

import dockerblade

daemon = dockerblade.DockerDaemon()
container = daemon.attach('name-of-the-container')

To perform filesystem operations on a container:

filesystem = container.filesystem()

# write text to a file
filesystem.write('/tmp/foo', 'Hello world!')

# remove a file (inspired by os.remove)
filesystem.remove('/tmp/foo')

# see API docs for more operations
...

To execute commands inside the container:

# specify the shell that should be used (e.g., /bin/sh, /bin/bash, /bin/zsh)
shell = container.shell('/bin/bash')

# obtain the value of an environment variable
val = container.environ('LD_LIBRARY_PATH')

# create a Popen
process = shell.popen('sleep 5')
retcode = process.wait()

# execute a command
assert shell.check_output('echo "Hello World"') == 'Hello World'

# see API docs for more operations
...
