5

How you can start using Docker today

• Getting your feet wet– Use Docker to build your apps– Use Docker for local development and/or testing environments

• Going all in– Start with smaller, new projects– Take time to learn best practices first

6

Building software using Docker containers

• Why?– Reliability– Reproducibility– Know your build environment– Greater flexibility

• How?– Utilize Docker images– Remember that containers are disposable and stateless

7

How to create Docker images

• docker run– Allows for quick iteration and testing– Not easily reproducible

• docker build– Gives you a template for how an image was made (a Dockerfile)– Dockerfiles should live with the code– Easy to reproduce and automate

Demo time!

Using Docker in your CI/CD pipeline

• Use your CI service to build your Docker images– Provides consistency– Store your images in a registry

• Use Docker containers in your CI/CD system– Adds flexibility– Easy to control software versions– No more “well it worked on my machine…”
