A simple web server

A simple web server in nodejs. It is intended for demo only, no production. A Dockerfile is provided in the reposistory to build a docker image and run the application as linux container.

On CentOS linux, install and start Docker

[root@centos ~]# yum install -y docker
[root@centos ~]# systemctl start docker

Install git and clone the reposistory

[root@centos]# yum install -y git
[root@centos]# git clone https://github.com/bsctl/nodejs-web-app
[root@centos]# cd nodejs-web-app

Build a Docker image

[root@centos nodejs-web-app]# docker build -t nodejs-web-app .
[root@centos nodejs-web-app]# docker images
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
nodejs-web-app        latest              e6e0578f5f2d        2 minutes ago       659.6 MB

Start the container by setting the desired answer message in the MESSAGE env variable

[root@centos]# docker run --name=web -p 80:8080 -d -e MESSAGE="Thanks for all the fish ..." nodejs-web-app
[root@centos]# curl localhost:80
