The objective of this exercise is to understand the basics of using GitHub Actions to work with our Containerfile. You will learn how to set up a workflow in GitHub Actions to automatically build and push a container image to a container registry using the defined Containerfile.

Instructions:

$1.$ Set up your working space:

Create a new repository on GitHub as "assignment$6".$

Initialize the repository with a README.

$2.$ Define a Dockerfile:

Create this Dockerrfile with anything you want.

Specify the base image, package installations, environment variables, and any other configurations you want for your container.

Add instructions to copy application code or files into the container and define the entry point command or script.

Save the changes to the Containerfile.

$3.$ Set up GitHub Actions:

In your GitHub repository, navigate to the "Actions" tab.

Click on "Set up a workflow yourself" to create a new workflow file.

Name the workflow file, as build$-$container.yml$.$

Replace the content of the workflow file with the following:

name: Build and Push Container

on:

push:

branches:

$-$ main

jobs:

build:

runs$-$on: ubuntu$-$latest

steps:

$-$ name: Checkout repository

uses: actions$/$checkout@v$2$

$-$ name: Login to Docker registry

uses: docker$/$login$-$action@v$1$

with:

username: $$\{\{$ secrets$.$DOCKER$\_$USERNAME $\}\}$

password: $$\{\{$ secrets$.$DOCKER$\_$PASSWORD $\}\}$

$-$ name: Build and push container

run: $|$

docker build $-$t my$-$container $.$

docker tag my$-$container $/$:

docker push $/$:

Click the Commit changes... button

A confirmation screen will appear; click the Commit Changes button again

Note: Replace $,,$ and with your desired values

$4.$ Define secrets:

In the GitHub repository, navigate to the settings tab

On the left side menu, click on "Secrets and Variables" $>$ "Actions".

Click on the "New repository secret"

Create two secrets: DOCKER$\_$USERNAME and DOCKER$\_$PASSWORD.

Set the values of these secrets to your Docker HUB username and password, respectively.

$5.$ Commit and push changes:

Add, Commit, and Push the changes to your repository.

$6.$ Verify the workflow execution:

Navigate to the "Actions" tab in your GitHub repository.

Verify that the workflow is triggered when you push changes to the main branch.

Monitor the workflow execution and ensure that it completes successfully.

$7.$ Verify the container image in the registry:

Access your container registry

Verify that the container image specified in the workflow file is built and pushed to the registry.

Be sure to fully document each step, document the entire process and document every terminal command in a seperate word document for review.
