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