Node.js Hello World
Node.js Hello World on CentOS using docker.
Prerequisites
Getting Started
-
Start Ubuntu virtual machine using Vagrant (required to run docker):
vagrant up
-
SSH into virtual machine:
vagrant ssh
-
Install dependencies:
cd /vagrant make install
-
Build docker image:
make build # docker build -t gasi/centos-node-hello .
-
Run app:
make run-container # docker run -d gasi/centos-node-hello
-
Install
curl
:sudo apt-get install curl
-
Get mapped port (last column) using, e.g. 49160:
docker ps > # Example > ID IMAGE COMMAND CREATED STATUS PORTS > ecce33b30ebf gasi/centos-node-hello:latest node /src/index.js 10 seconds ago Up 9 seconds 49160->8080
-
Test app using the port in previous step, e.g. 49160:
curl localhost:<port> # Example # curl localhost:49163
It should print
Hello World
to the console.
