Docker and Kubernetes: The Complete Guide

Docker and Kubernetes: The Complete Guide

This repository contains my solutions to the exercises from the Docker and Kubernetes: The Complete Guide course.

Course available at Udemy

Projects

• redis-server: Use a redis:latest image as a base image, download and install a dependency and tell the image what to do when it starts as a container.

• nodejs-app: A simple node.js/express.js "Hello world" application. Use a node:10-alpine as a base image and change the image's working directory, copy/install dependencies and run a default command.

• visits-app: A node.js/express.js application that counts the number of page visits. It uses two containers, one for the Node.js server and the other for Redis to store the number of page visits value.

• react-app: A simple react.js application running on a container. It uses different containers for different working environments:

  • One container for the development environment which uses a node:10-alpine as a base image and runs a local development server via npm run start command.
  • One container for the testing environment which uses a node:10-alpine as a base image and runs the test suites via npm run test command.
  • One container for the production environment which uses a node:10-alpine as a base image and runs the production build process via npm run build command. And another container that uses nignx:alpine as a base image and run a Nginx web server to server the static content reside in the build folder.

• multi-container-app: Multi-container app which constists of three containers interacting together to save indices and compute fibonacci series of them. These containers are deployed in a Kuberenetes cluster and use Ingress services to interact with together.

What I have learned

• Download and install Docker in different environments such as Linux, Windows and MacOS.
• Use Docker CLI to inspect and debug running containers.
• Build custom Docker images through the Docker Server.
• Use Docker Compose to define and run multi-container Docker applications.
• Create and configure multi-step Docker builds.
• Use Kubernetes different objects such as Deployment, NodePort Service, ClusterIP Service, Ingress, etc. to deploy a fully functional application with multiple containers.
