My solution to She Code Africa Cloud School - Technical Assesment(Exercise 1).

Getting Started

These instructions will get you a copy of the project up and running on your local machine.

Instructions

  • Checkout to stable branch.

  • Inside the docker folder, Create a package.json file and add the following code.

{
    "name": "sca_app",
    "version": "1.0.0",
    "description": "create a dockerfile on Nodejs project",
    "author": "Mariam Adedeji",
    "main": "server.js",
    "scripts": {
      "start": "node server.js"
    },
    "dependencies": {
      "express": "^4.16.1"
    }
  }
  • Create a node.js app in the server.js file using express. This file should contain the following code.
'use strict';
const express = require('express');
const app = express();

app.get('/', (req, res) => {
  res.send('Welcome to SCA Cloud School Application');
});

app.listen(3000, () => console.log('Server ready'))

  • Run npm install to install the packages listed in the package.json file.

  • Create a Dockerfile with the following content.

FROM node:8
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3000
CMD [ "npm", "start" ]

  • Download and installed Docker Desktop Installer and wsl_update.

  • Run the following code on shell to build the image.

docker build -t image .

For example:

docker build -t sca_cloud_school_application .
  • Run the following to run a container from the image.
docker run -d -p 3000:3000 --name username image

For example:

docker run -d -p 3000:3000 --name sca-app sca_cloud_school_application

  • Make your changes and checkout to feature branch.

  • Update the line 6 of server.js with the following:

res.send('Welcome to SCA Cloud School Application , this is my first assessment');
  • Run the following code on shell to build the image.
docker build -t image .
  • Run the following to run a container from the image.
docker run -d -p 3000:3000 --name username image

The image is running in the Docker Desktop image

The app is running on port 3000 b

  • Use the docker tag to give the image a new name.
docker tag image username/tag-name

For example

docker tag sca_cloud_school_application mariehposa/sca_cloud_school_application
  • Use the docker hub to push it to Docker Hub.
docker push YOUR-USER-NAME/tag-name

For example

docker push mariehposa/sca_cloud_school_application
