Artsy Docker development toolkit

Project description


Hokusai is a Docker + Kubernetes CLI for application developers.

Hokusai "dockerizes" applications and manages their lifecycle throughout development, testing, and release cycles.

Hokusai wraps calls to kubectl, docker, docker-compose and git with a CLI, and defines a CI workflow.

Hokusai currently only supports Kubernetes deployments on AWS, configured to pull from ECS container repositories (ECR), although other providers may be added in the future.

Why Hokusai?

At Artsy, as we began working with Kubernetes, while impressed with its design, capabilities, and flexibility, we were in need of tooling we could deliver to agile development teams that addressed the day-to-day tasks of application development, delivery, introspection and maintenance, while providing a clean and uncomplicated interface.

Transitioning teams to the Docker / Kubernetes ecosystem can be intimidating, and comes with a steep learning curve. We set out to create a Heroku-like CLI that would shepherd the application developer into the ecosystems of Docker and Kubernetes, and while introducing new tooling and concepts, outlining a clear practice for dependency management, local development, testing and CI, image repository structure, deployment and orchestration.


  1. Python 2.7 or 3.5 and pip

It's recommended that you use pyenv to install the correct version of python. See this guide for working with pyenv.

# Only if you don't already have pyenv installed
brew install pyenv

pyenv install -s

Before installing pythons via pyenv, make sure you are using brew-installed libraries openssl, readline and xcode-installed zlib and these libraries are correctly linked. For example:

brew install openssl

If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

Now, when installing pythons you should see the following output.

$ pyenv install 3.5.8

python-build: use openssl from homebrew
python-build: use readline from homebrew

Downloading Python-3.5.8.tar.xz...
Installing Python-3.5.8...
python-build: use readline from homebrew
python-build: use zlib from xcode sdk

Installed Python-3.5.8 to $HOME/.pyenv/versions/3.5.8

Note: If you want to create a PyInstaller distribution (by running make build) you need to install Python with development dylibs. Use the environment variable PYTHON_CONFIGURE_OPTS="--enable-framework" on Darwin and PYTHON_CONFIGURE_OPTS="--enable-shared" on Linux when running pyenv install.

  1. Virtualenv and Poetry

It's recommended that you use Virtualenv to manage different project dependencies, though this is not required. See this guide to get started with virtualenv management.

pip install virtualenv virtualenvwrapper
mkvirtualenv hokusai
workon hokusai

Use poetry to install development dependencies. See this guide for working with poetry.

Install poetry:

pip install poetry

Install dev dependencies:

poetry install --no-root

Update dev dependencies:

poetry lock

To install hokusai package dependencies from in "editable" mode, run

pip install -e .

Other installation methods can be found in the project's repo

  1. Docker

If you use homebrew on OSX, install Docker for Mac with: brew tap caskroom/cask && brew cask install docker

  1. Docker Compose

If you installed Docker for Mac, docker-compose is also installed. Otherwise install with: pip install docker-compose.

  1. Git


If you're on OSX, the preferred installation method is via homebrew:

$ brew tap artsy/formulas
$ brew install hokusai

If you've previously installed hokusai via an alternate installation method, you may need to force the link step. If you installed hokusai via pip, you may also want to cleanup that installation:

$ pip uninstall hokusai
$ brew link --overwrite hokusai

If you are on Linux:

curl -sSL | sudo bash

Alternate Installation Methods

Via pip

Note: If installing via pip fails due to pip failing to upgrade your system Python packages, try running pip install hokusai --ignore-installed.

Via curl

Note: You may need to adjust the target destination to match a directory in your $PATH.

curl --silent$(uname -s)-$(uname -m) -o /usr/local/bin/hokusai && chmod +x /usr/local/bin/hokusai


  1. Configure your AWS credentials.
  2. Run hokusai configure --kubectl-version <kubectl version> --s3-bucket <bucket name> --s3-key <file key>. You'll need to provide the kubectl version matching your Kubernetes deployments, as well as the S3 bucket name and key of your org's kubectl config file. System administrators: see Administering Hokusai for instructions on preparing AWS, Kubernetes, and publishing a kubectl config file. Artsy devs: see these artsy/README docs for the current way to install and configure hokusai.

To enable bash autocompletion: eval "$(_HOKUSAI_COMPLETE=source hokusai)"

Getting Started

See Getting to start using Hokusai for your project.

Command Reference

A full command reference can be found in Command

Developing Hokusai

To work on Hokusai itself, set up your local development environment like so:

  • As above, install python, poetry, docker, docker-compose and git.

To install the Hokusai package in "editable mode" from a checkout of this repository, you can run pip install --editable . This works well in combination with Virtualenv/Virtualenvwrapper as you can install the project in editable mode within a virtualenv, and from a release in your default system environment.

Testing Hokusai

Hokusai is currently tested on Pythons 2.7.16 and 3.5.8.

  1. Install poetry (see above).

  2. Install dependencies: poetry install --no-root.

  3. Run tests

All tests can be run with make tests.

Only run unit tests: make test Only run integration tests: make integration

Tests for specific modules, TestClasses, or even methods can be run with python -m unittest test.unit.test_module.TestClass.test_method

Set the DEBUG=1 environment variable to print boto logging

Review Apps

Hokusai can be used to simplify the process of spinning up a "review app" instance of your project, based on a feature branch or pull request.

Full details are in the Review App reference.

Distributing Hokusai

Merges to master automatically distribute Pyinstaller versions for beta testing at and respectively.

To create a new release, bump the version by editing the ./hokusai VERSION file, create an entry in and open a PR from master to the release branch of this repo.

The Name

The project is named for the great Japanese artist Katsushika Hokusai (1760-1849).
