TypeScript Sample Application

This repository provides a simple starting point for running TypeScript applications on OpenShift. It can also be applied to applications that use Babel or other transpilers. A blogpost that runs through the details of this repository and OpenShift can be found here.

Running on OpenShift via Nodeshift

To use this method of deployment you'll need:

Nodeshift is a neat CLI that simplifies deployment of Node.js applications on OpenShift. This project incldues Nodeshift in devDependencies so you can simply run the following to deploy it on an OpenShift instance:

$ git clone git@github.com:evanshortiss/openshift-typescript-example.git ts-openshift

$ cd ts-openshift

# Ensure you are logged into your openshift instance
$ oc login

# Choose the project you'd like to deploy this applicaion into
$ oc project myproject

# Build and deploy
$ npm run nodeshift -- --expose

If you're deploying on a locally running instance of OpenShift you might need to do the following to bypass the self-signed certificate issues:

$ npm run nodeshift -- --expose --strictSSL=false

Running Locally without Docker

To run this application locally you'll need:

  • Node.js v6 or later
  • npm v3 or later
  • Git

Exectute the following commands to start the program locally:

$ git clone git@github.com:evanshortiss/openshift-typescript-example.git ts-openshift

$ cd ts-openshift

$ npm install

$ npm run build

$ npm start

If you're developing locally you automated code watching and reloading via:

npm run start-dev

Running Locally using Docker and s2i

To perform the following steps you'll need:

With both tools installed you can execute the following commands to run your application locally in an environment that matches that it will use when deployed on OpenShift Online.

# Build the latest local commit into a container image
# If you have uncommitted changes add the "--copy" flag
$ s2i build . registry.access.redhat.com/rhscl/nodejs-8-rhel7 openshift-ts

# Run our container image
$ docker run -p 8080:8080 -dit --name openshift-ts openshift-ts

This instructs s2i to build our source code into an image that will be tagged as "openshift-ts". The base image used the official Red Hat Node.js v6 image. Once the build is complete we run it using Docker and expose its port 8080 to our local port 8080.
