I'm starting a new project for my resume and learning, specifically a budget web app. The tech stack will include React for the front end, Django for the back end, and PostgreSQL for the database. A lot of people keep suggesting that I use Docker for this project, but I'm a little hesitant since I feel like I'm already juggling quite a bit with learning new technologies. I'm pretty confident with Python and Django, comfortable with HTML and CSS, just getting into Tailwind and JavaScript, and also new to PostgreSQL, although I have some experience with MySQL. My concern is whether it's a good idea to dive into learning Docker at the same time. I've avoided learning Redis in the past because I felt I needed Docker first. Should I just go for it now?

There might be times when using Docker isn't necessary, particularly if your project doesn’t benefit from containers. But for a web application, I'd say it's a solid reason to use it.
Go for it! Docker can be intimidating at first, but it's not as complex as it seems. Familiarizing yourself with things like environment variables and volume mappings is key. The more you use it, the more straightforward it becomes. Plus, Docker Compose is a great tool that lays things out clearly, and there are even tools to convert Docker Run commands to Compose files to make the transition easier.
Good luck figuring out volumes! That can be tricky since it's all about how to properly back up and restore your data. Just keep an eye on that.
Absolutely dive into Docker! You won’t regret it. Running your PostgreSQL in a container is way easier than managing it directly on your machine, trust me. Once you get the hang of it, it simplifies deployment massively. Just try running a command like `docker run -d --name mydb -p 4040:4040 -v data:/var/lib/postgresql/data postgres:latest`, and you'll see how quickly you can have your database up and running!
For real! Once you start with containers, it’s hard to go back to the old ways. Everything is so much more organized and hassle-free.
Exactly, a web app is a perfect use case for Docker! It helps keep dependencies organized and manageable.
