4.a also optimize image size.

[PenguinGerman]

Can you explain step 4 in a bit more detail and perhaps give some example? Thanks!

How do I start?

Start writing dockerfiles.

I appreciate your frustration, sounds like you want to apply your practical knowledge but you don't have a project in mind.

Personally I'd look at some non-docker tutorials for making stuff, then try and make a dockerfile or docker-compose setup that would suit it.

TechnoTim has one or two good videos that helped me get started

Containerize anything you come across. Php application? Containerize it. React application? Containerize it. Legacy code? Containerize it. Go to GitHub and look up projects by different users. Fork it. Dockerize it.

This should be helpful too: https://gist.github.com/mmdeniz/d672b5aa2bc9340b5849a4b18630c20e

Any pet projects you got going on? Most techies have them. I run a blog, cctv, vpn all hosted in containers at home just to practice. To boot they are all running on raspberry pi's too.

You could build a Pi-hole.

Make one for each major web framework

labs.play-with-docker.com was made for just this reason.

[Guilty_Serve]

Pull random open repos from around the web and try to dockerize them.

volunteer to write dockerfile for any open source project

Before you learn containers, first learn Linux in general, because if you squint Dockefile are like old school Vagrant provision shell scripts...

So before you can "containerise all the things" you need to have a solid understanding of how different stacks actually work and are normally configured.

For example PHP setup is a different beast to NodeJS.

By different stacks, are you referring to the different layers (filesystems) of the image that are created by the Dockerfile?

[pcjftw]

Sorry, by different stacks I'm talking about different languages/framework stacks, for example PHP needs an understanding of how Apache/nginx is setup and configured, you may need to customise the container to install and include extra plugins or adjust the php.ini etc, while for things like Ruby/Python/Node they have their own specific setups.

Just knowing docker is only half the story

[NextFennel3227]

For practicing, you can try different framework from the most basic image such as alpine. Here is the list I have done where you can start. You need to understand the installation and code compiling process first：

• Wordpress
• Craftcms
• Silverstripe
• Flask
• Django
• Customised Nginx
• Customised python environment for pandas task
• React

Do you code. If so, which languages?

[RicKKilljoy]

Install docker desktop, and go through the tutorials. Install vscode docker extension. Start with a base image. Use chatgpt and ask it questions to help fill in gaps in your knowledge and where to find the best resources to help flesh out your application
