• This is a seriously well done explanation not only of Docker, but of good development environment setup in general. I'm working to get my team more in sync with these kinds of practices.

• Youre superior for creating this web hosting video! Ive experimented with GoDaddy and A2 Web Hosting, but Cloudways with TST20 coupn is the ultimate saver.

• The lighting for the video is good, but please pay more attention to the audio. You can probably use a collar microphone or equalize the volume in post production. Thanks for the great content.

• 🎯 Key Takeaways for quick navigation:

  00:00 🐳 Docker helps ensure local development matches cloud environment for compatibility.
  01:29 🐍 A simple Python API example using FastAPI to retrieve YouTube channel information.
  03:21 🚀 Unicorn used to run the server, exposing it on port 8080, with an option for automatic reloading on code changes.
  05:16 🌐 Docker provides an isolated environment for running applications, reducing compatibility issues between different environments.
  07:12 🤝 When working in a team, it's crucial to make development environments as similar as possible to avoid errors.
  09:08 🏗️ Docker images are built based on Dockerfiles, specifying the environment and dependencies for an application.
  12:01 🔄 Manually restarting the Docker container for code changes is inefficient; Docker Compose offers automatic reloading for local development.
  15:30 📁 Docker Compose uses a YAML file to define settings for building and running containers, including volume syncing for code changes.
  19:19 🔄 Use "reload include" in Docker Compose to specify which files to monitor for changes and trigger automatic server reloads.
  21:42 📦 Docker allows for flexible, isolated, and synced virtual development environments, ensuring compatibility between local and cloud deployments.

• Thank you for the video, it helps a lot

• You are a f'ing amazing teacher. Most clear video of this topic on YouTube by far. Subscribed!

• make video about docker, spend 2 minutes walking thru basic python api.

• I've been developing software for 20+ years and always used virtual environments for Python – I feel really behind the curve here, but have been curious about utilizing containers and watched a number of videos. Yours is easily the most clear, concise, and logically understood tutorial I could find. I had previously tried Patrick Loebers tutorial but found he had missed a number of critical steps and made a non-trivial amount of formatting errors.

  So thanks for this tutorial, much appreciated!

• "Home – ah – gen – ize"

• Thank you, great explanation and very helpful tips

• Thanks Arjan, this is an awesome video! The problem–solution–problem–solution format really helps me understand why we need docker and docker-compose. Also the tip of putting the install dependencies command before copying project folder is so important. Keep it up man!

• Huge thanks

• would be nice a video about dev containers / github codespaces

• Hi! Which plugin you are using for zsh to have such nice intellisense?

• Very helpful, thanks. At 09:17 you talk about building your image upon the python:latest image; where does that come from? Is this the name of an image that's made available by someone somewhere? Where is it retrieved from?

• Yet again Arjan saves the day. I was smashing my head for hours trying to figure out how to setup a CMD command in the Dockerfile with lektor instead of uvcorn, where the commas and quotes are etc. Not only it helped me with that, but it showed me that I can actually just write the full command in the compose file, so I don't have to deal with all the specifics

• 7:42 It's pronounced "Hoe-MAH-gen-ize".🙂 Your English is nearly perfect–I'm surprised you had trouble with that word.
  No matter how you pronounce it, though, your content is great!!

• Clear, concise, to the point and working. Good job!!
