Cloud & DevOps
Learn Docker
Docker packages your application together with everything it needs to run into an image. That image runs the same way on your laptop as it does on a server.
Why teams use it
- It removes the "works on my machine" class of problem.
- Starting a database or dependency locally becomes a single command.
- Cloud platforms can run a container without knowing anything about your language or framework.
Where you will meet it
The Anvi website itself is built into a container image and run that way, which is why the same build works locally and in the cloud.
What to learn, and in what order
Work through these roughly in order. Jumping to the advanced list before the basics are solid is the most common way people get stuck.

- Writing a Dockerfile
- Building and running
Intermediate
- Ports, volumes and networks
- Environment variables and configuration
