Docker – How to Setup Typescript Development Environment

Following are the key points described later in this article:

• Build NodeJS & NPM image
• Build Typescript image
• Create Typescript container
• One script to create images & Typescript container

Build NodeJS & NPM Image

Following code can be used to create NodeJS/NPM image.

# Use base image of centos6
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

Place the code in a file and name it as nodejs_base.df. The above code could be used to build the nodejs image using following command:

docker build -t nodejs_base -f nodejs_base.df .

Build Typescript Image

Following code assumes that above image is built with tag “nodejs_base”.

FROM  nodejs_base

RUN npm install -g typescript		

Place the code in a file and name it as typescript.df. The above code could be used to build the typescript image using following command:

docker build -t typescript -f typescript.df .

Create Typescript Container

Once the “typescript” image is built, one could create the container where typescript files could be compiled. Following command could be used to build the typescript container.

docker run -ti -dP --name ts1 -v /c/Users:/mnt/Users typescript /bin/bash

Type “tsc –help” command and it should print the information in relation with tsc and different options.

One Script to Create Node/NPM Image & Typescript Container

Following script could be used to create Typescript container.

#!/bin/sh

if [ $# == 0 ]; then
  echo "This script expect container name argument. Example: ./installTS.sh ts1"
  exit 100
fi

# Build NodeJS image if it does not exists
#
nb_image="nodejs_base"
nb_df="nodejs_base.df"
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
  fi
fi

# Build Typescript image if it does not exists
#
ts_image="typescript"
ts_df="typescript.df"
if [ `docker images $ts_image | wc -l` -lt 2 ]; then
  echo "Docker Image $ts_image do not exist..."
  echo "Builing docker image $ts_image"
  if [ -f $ts_df ]; then
    docker build -t $ts_image -f $ts_df .
  else
    echo "Can't find Dockerfile $ts_df in the current location"
    exit 200
  fi
fi

docker run --privileged=true -ti -dP --name $1 -v /c/Users:/mnt/Users $ts_image /bin/bash
