---

Course Requirements:

1. Laptop (with admin privileges)
2. Desire to Learn.

---

Module 1: Docker Basics

• What is Docker?: Overview of containers vs VMs.
• Install Docker: Set up Docker on Windows/macOS/Linux.
• Run Containers: Start a container using docker run <image>.
• Container Lifecycle: Manage containers (docker ps, docker stop, docker rm).

---

Module 2: Docker Images

• What are Docker Images?: Layers, file system, and reusable components.
• Pull Images: docker pull <image-name>.
• List and Remove Images: docker images, docker rmi <image-name>.
• Create Custom Images: Build images using a Dockerfile.

---

Module 3: Dockerfile & Multi-Stage Builds

• Dockerfile Basics: Instructions like FROM, RUN, COPY, CMD.
• Efficient Image Creation: Automate build processes using Dockerfile.
• Multi-Stage Builds: Optimize image size by using multiple stages in a Dockerfile.

---

Module 4: Docker Networking and Volumes

• Docker Networking: Understand bridge, host, and custom networks.
  • Create custom networks: docker network create <network-name>.
  • Link containers via networks.
• Docker Volumes: Use volumes to persist data.
  • Create and mount volumes: docker volume create <volume-name>.
  • Attach volumes to containers: docker run -v <volume-name>:<path>.

---

Module 5: Docker Registry & Image Management

• Docker Registry: Docker Hub and private registries.
• Push/Pull Images: Push image to Docker Hub (docker push <image-name>), pull image from Docker Hub (docker pull <image-name>).
• Image Management: Tag images (docker tag <source> <target>), remove unused images (docker rmi <image-name>).

---

Module 6: Docker Compose

• Introduction to Docker Compose: Manage multi-container apps with docker-compose.yml.
• Start and Stop Containers: docker-compose up, docker-compose down.
• Scaling Containers: Define multiple instances of a service in Compose.

---

Module 7: Docker Image Scanning & Security

• Image Scanning: Use tools like Clair or Trivy to scan Docker images for vulnerabilities.
• Security Best Practices:
  • Use trusted base images.
  • Avoid running containers as root.
  • Use Docker Content Trust (DCT) to sign images.
  • Regularly update images to patch security vulnerabilities.

---

Module 8: End-to-End Project: Dockerized Web App

• Step 1: Create a Simple Web App:
  • Choose a language (e.g., Python Flask or Node.js) and build a basic web app.
  • Write a Dockerfile to containerize the app.
• Step 2: Set Up Docker Compose:
  • Add a database (e.g., MySQL or MongoDB) using Docker Compose.
  • Define multi-container services in docker-compose.yml.
  • Link the web app and database using Docker networks.
• Step 3: Automate Builds:
  • Build the image: docker build -t <app-name> ..
  • Push the app image to Docker Hub: docker push <image-name>.
• Step 4: Deploy with CI/CD:
  • Set up a simple Jenkins/GitLab pipeline to automate the build, test, and deployment.
  • Use Docker to deploy the app on a cloud server (e.g., AWS, Azure).

---

Module 9: Final Project

• Create a Complete Dockerized Application:
  • Build and deploy a multi-container app (e.g., a web app with backend and database).
  • Use Docker Compose for orchestration.
  • Implement a CI/CD pipeline to automate testing and deployment.
  • Scan Docker images for vulnerabilities and apply security measures.
