Dockerized Bluemix Development Environment

Introduction

Rather than configuring your actual development environment for IBM Bluemix, it makes more sense to create a Dockerfile.

Within a launched container we have full access to Bluemix, and can even push anad manage other containers.

Usage

I launch a container using this script:

$ sudo docker build -t craig/bluemix .
$sudo docker run --privileged -t -i -p 4444 craig/bluemix

Configuring a local dev environment for IBM Bluemix

What is IBM Bluemix?

Using this great pizza-as-a-service paradigm, Bluemix is a SASS:

Fig 1: Bluemix is a SAAS

Developers can use existing Bluemix services, including Alchemy API:

Fig 2: Watson services on Bluemix

Developers can also deploy their own services, including containers using Docker technology.

This article will walk through the setup of a local development environment for working with Bluemix. All scripting and configuration is for Debian64-bit (Ubuntu 14.10 at the time of this article).

Python Development Environment

The first step is to create a python development environment.

# install pip 
sudo apt-get \
  install -y \
    build-essential \
    python-dev \
    python-pip

# install python setup-utils
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

pip is a package management system used to install and manage software packages written in Python and Setuptools is a package development process that enhances the Python standard library distribution utilities.

Installing Docker

Instructions for installing docker on Ubuntu are referenced below and the script is replicated here:

# add the Docker repository key to your local keychain: 
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9

# add the Docker repository to your apt sources list: 
sudo sh -c "echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list"

# prior to using any Ubuntu-maintained package installation, ensure existing packages are up to date: 
sudo apt-get update

# install the Docker-LXC package: 
sudo apt-get install -y lxc-docker

# install docker compose:
wget https://github.com/docker/compose/releases/download/1.1.0/docker-compose-$(uname -s)-$(uname -m)
mv docker-compose-$(uname -s)-$(uname -m) docker-compose
sudo chmod 777 docker-compose
sudo mv docker-compose /usr/local/bin/
docker-compose --version

Docker is a container-based software framework for automating deployment of applications. “Containers” are encapsulated, lightweight, and portable application modules.

IBM Extensions

Before you can create a container in Bluemix, you must install the IBM Containers Extension (ICE):

sudo apt-get \
  install -y \
    curl

# install ice
export ICE=icecli-2.0.zip
curl -O https://static-ice.ng.bluemix.net/$ICE
sudo pip install icecli-2.0.zip
rm $FILE
ice version

Cloud Foundry

Finally, we need to install the Cloud Foundry command line interface:

# install CF
export FILE=cf-cli_amd64.deb
wget -O $FILE https://cli.run.pivotal.io/stable?release=debian64&version=6.11.0&source=github-rel
sudo dpkg -i $FILE
sudo apt-get install -f -y
rm $FILE
cf --version

Miscellaneous Commands

We need to endsure that the necessary environment variables are set, user authorizations are in place and configuration files are correct.

# set docker env var
sudo sh -c 'echo "export DOCKER_TLS_VERIFY=1" >> /etc/environment'

# modify user authorization
sudo usermod -a -G docker $(whoami)

By default, the ice commands must be run with root authentication and therefore, require the prefix sudo. This last command will allow us to run docker and ice commands without sudo.
