Motivation

Creating a single droplet provisioned to use docker should be quick. Ansible and Terraform are the appropriate tools but may take long to configure for a single droplet. This package provides a simple cli to streamline the use of these tools.

Installing

Install the package from pypi:

pip install docker-droplet

Alternatively, you can clone the repo:

git clone https://github.com/JoelLefkowitz/docker-droplet.git

Running the package

Usage:
   docker-droplet up [options]
   docker-droplet down [options]

To create a terraform configuration and run an ansible playbook to install docker:

docker-droplet up --droplet-name steve --ssh-key /home/.ssh/steve.pub --token 12345 --config-path /Workspace/config.tf

Where the terraform configuration path defaults to "./config.tf"

The droplet's name, ssh key path and digitalocean token will be synchronized with environment variables:

export TF_VAR_DOCKER_DROPLET_DROPLET_NAME=steve
export TF_VAR_DOCKER_DROPLET_SSH_KEY=/home/.ssh/steve.pub
export TF_VAR_DOCKER_DROPLET_TOKEN=12345
docker-droplet up

A domain and digital ocean project title can also be specified

docker-droplet up --domain example.com --project example

To remove the structure simply take it down:

docker-droplet down --token 12345 --config-path /Workspace/config.tf

Running tests

Tests are not included in the package build. Clone the repo to include all the source files.

What is being tested

Unittests are used to test for appropriate behavior from:

• The template's loader
• The interface's argument validation
• The interface's path_validation

Docs

Docs are not included in the package build. Clone the repo to include all the source files.
