Docker – Create Javascript Development Environment

• Javascript Development environment
• Dockerfile representing JS Development Environment
• One script used for Images/Containers

Javascript Development Environment

Following tools are installed to make Javascript development environment.

• NodeJS runtime
• Typescript compiler
• Grunt-cli
• Bower
• JSHint for code quality check
• Jasmine for unit tests

Dockerfile representing JS Development Environment

Following dockerfile (nodejs_base.df) could be used to create NodeJS base image and represents NodeJS runtime.

# Use centos6 base image
FROM    centos:centos6

# Enable Extra Packages for Enterprise Linux (EPEL) for CentOS
RUN     yum install -y epel-release

# Install Node.js and npm
RUN     yum install -y nodejs npm

Following Dockerfile (javascript.df) is used to create Javascript Dev Environment image representing following tools:

• Typescript compiler
• Grunt-cli
• Bower
• JSCS
• Browserify
• JSHint for code quality check
• Jasmine for unit tests

FROM  nodejs_base

# Install Typescript
RUN npm install -g typescript

# Install Grunt CLI
RUN npm install -g grunt-cli

# Install Bower
RUN npm install -g bower

# Install jshint
RUN npm install -g jshint

# Install Browserify
RUN npm install -g browserify

# Install JSCS
RUN npm install -g jscs

# Install Jasmine
RUN npm install -g jasmine

RUN mkdir /spec
RUN mkdir /spec/support

RUN jasmine init

One script used for Images/Containers

Following script (installJS.sh) could be used to create Javascript Dev environment. It includes following:

• Creation of NodeJS runtime image
• Creation of Javascript tools image

#!/bin/sh

if [ $# == 0 ]; then
  echo "This script expect container name argument. Example: ./installTS.sh jsdev"
  exit 100
fi

if [ `docker images $nb_image | wc -l` -lt 2 ]; then
  echo "Docker Image $nb_image do not exist..."
  echo "Builing docker image $nb_image"
  if [ -f $nb_df ]; then
    docker build -t $nb_image -f $nb_df .
  else
    echo "Can't find Dockerfile $nb_df in the current location"
    exit 200

  echo "Docker Image $js_image do not exist..."
  echo "Builing docker image $js_image"
  if [ -f $js_df ]; then
    docker build -t $js_image -f $js_df .
  else
    echo "Can't find Dockerfile $js_df in the current location"
    exit 200
