Flask App Deployment with Gunicorn and Environment Variables

Today I gained an interesting insight into Docker image sizes. When I use python:3.12, the image size is around 1.82GB. But when I switch to python:3.12-alpine, it’s amazing to see that the size drops to just 293.42MB. This happens because python:3.12 is based on a Debian image, whereas Alpine is built on Alpine Linux, which uses a minimal operating system. Of course, there are some trade-offs, such as missing pre-installed packages. As a beginner learning Docker, I’ve realized that Docker is not just about containers, tools, or commands. It’s about understanding the core concepts of operating systems how cgroups and namespaces work in Linux, and why tools like Docker Desktop are needed. It’s truly about understanding the underlying system and its architecture. I’m grateful to be learning this through Habib vai’s tutorial. #Happy_Learning #Docker #DevOps

Docker containers are the new node_modules. We went from: > 500MB dependencies in package.json > To 2GB base images with Alpine Linux > To 8GB with "lightweight" Python ML stacks We're just moving the bloat around. Same shit, different abstraction layer.

💻 I Spent 2 Hours Debugging… for a 2-Minute Fix While practicing Python on Linux, I ran into a simple issue: My script just wouldn’t run. No output. No clear error. After trying multiple things, I finally found the problem 👇 👉 I was running the file incorrectly in the terminal 👉 And missed checking the Python version. Fix: ✔️ Used python3 file.py instead of python file.py ✔️ Verified with python3 --version Simple mistake. But it cost me 2 hours. What I learned: Small details matter a lot in tech Always check basics before overthinking Debugging is where real understanding happens Moments like these can feel frustrating, but they’re also the ones that stick the most. Curious—what’s a “simple mistake” that cost you hours? #Python #Linux #Debugging #DevOps #LearningJourney #TechLearning #Beginners

⚠️ Skipping virtual environments is one of the most common mistakes new Python developers make. Here is why it matters and how to do it right. A virtual environment keeps your project dependencies isolated. Without one, every package you install goes into your global Python installation and things break fast when projects need different versions of the same library. Here is how to set one up for your FastAPI project: 🔧 Step 1: Create the virtual environment python -m venv environmentfoldername ⚡ Step 2: Activate it On Windows PowerShell: .\environmentfoldername\Scripts\Activate.ps1 On Mac, Linux, or Git Bash: source environmentfoldername/Scripts/activate Once activated, your terminal will show the environment name. That is your green light to start installing packages safely. ✅ 🙅 One more thing: always add your environment folder to .gitignore. You do not want to push hundreds of dependency files to GitHub. Virtual environments are a small habit that save enormous headaches. Start doing this from day one. #Python #FastAPI #DeveloperTips #CleanCode #PythonDevelopment

💻 Four words. Zero fluff. "Talk is cheap. Show me the code." — Linus Torvalds In tech, your work speaks louder than your words. Anyone can say they know React, Python, or System Design. But your GitHub, your projects, your commits — those don't lie. -> Stop overthinking. Start shipping. -> Stop planning perfectly. Start building messily. -> Stop talking about what you'll build. Build it. The best portfolio is the one you actually push. #OpenSource #Linux #Developers #BuildInPublic #Code #SoftwareEngineering
