## Learning Outcomes
- Assess techniques for optimizing image builds through layer caching, tag management, and disk-space pruning
- Differentiate interactive, detached, and named container execution modes and their corresponding operational scenarios
- Evaluate security best practices for choosing trusted base images, minimizing installed packages, and limiting user privileges within containers
- Identify essential Docker CLI commands to pull images, start and stop containers, view logs, and manage images
- Recognize proper syntax and sequencing for key Dockerfile instructions, including FROM, RUN, COPY, CMD, WORKDIR, USER, ARG, and ENV
## Traditional Course Outline
1. Using Docker Containers - You'll go from starting and stopping your first container to seeing how to clean your environment by removing all containers and images. You'll see how to debug issues by running commands inside a container or executing bash commands in a container interactively. All of this is done using the Docker Command Line Interface.
2. Writing Your Own Docker Images - Once you are able to manage images and containers, it's time to know how to share images with colleagues or your entire company and to understand how to create your own. Now, you'll build your own images using Dockerfiles. Dockerfiles are text files that include everything needed for Docker to build an image. You'll learn how to create images and will get an introduction to all the essential Dockerfile instructions like FROM, RUN, COPY, and more. By the end of this chapter, you'll have insight into how Docker makes images and be able to create optimized Docker images from scratch.
3. Creating Secure Docker Images - In this final chapter, you’ll focus on making your Dockerfiles configurable and secure. You'll learn how to make your Dockerfiles configurable using the ARG and ENV instructions. You’ll see why changing the user in your images makes them more secure and how to use the USER Dockerfile instruction to do so. To wrap things up, you’ll learn about some essential security best practices when creating Docker Images.
