Just built and ran my first Python app inside Docker 🚀 Today I containerized a simple Python script using Docker and successfully passed environment variables into the container at runtime. What’s happening here: A Python app (hello.py) reads an environment variable: STUDENT_NAME A Dockerfile builds the app into an image I run the container twice: once without the variable → “No student name provided” once with -e STUDENT_NAME=Alice → “Student name: Alice” This small project helped me understand: How Docker images are built How containers run in isolation How environment variables work inside containers The difference between build-time and run-time configuration It’s a simple example, but it shows the core idea of portable, reproducible environments the same app runs the same way anywhere. Step by step, building real DevOps skills. More to come. 💻🐳 #Docker #DevOps #Python #LearningByDoing #Cloud #Containers #TechJourney

Interactive Telegram Bot Developed with Python 🤖 I'm excited to share a quick demonstration of a Telegram Bot I built using Python. In this video, I walk through the various interactive buttons and features I've implemented to automate specific tasks. To ensure 24/7 availability, the bot is hosted on PythonAnywhere with scheduled tasks to manage its uptime efficiently. This project helped me deepen my understanding of APIs, asynchronous programming, and cloud deployment. #Python #TelegramBot #Automation #SoftwareDevelopment #PythonAnywhere #CodingSkills

The best way to learn Docker: pull an image, run a container, exec into it—experience beats theory every time. The best way to get started with Docker is to run a few containers from local and DockerHub-hosted images and experience the most typical use cases of the 'docker run' command firsthand. #Docker #DevOps #Containers #DockerHub #LearnDocker #BackendEngineering #SoftwareEngineering #Dockerfile #ContainerOrchestration #CloudNative #Microservices #TechEducation #DockerCommands #Kubernetes #WebDevelopment #Python #NodeJS #DevTools #Infrastructure #HandsOnLearning

Hello LinkedIn I’ve been spending time strengthening my skills in backend development with Python and Django, and it’s been exciting seeing how everything connects — from models and views to authentication and database interactions. One thing I’m learning is that building small projects consistently teaches more than just watching tutorials. Each bug fixed and feature added builds confidence. I’m continuing to learn, build, and improve every day 🚀 If you’re also on a learning journey or working in backend development, I’d love to connect! #Python #Django #JuniorDeveloper #SoftwareDevelopment

Your Docker image might be bigger than it needs to be. 🐳 When installing Python dependencies inside a container, 𝘱𝘪𝘱 stores downloaded packages in its cache, which makes perfect sense on a local machine. But inside Docker? Image layers already provide caching. Keeping the 𝘱𝘪𝘱 cache only increases image size without adding value. In production, that means: • Larger images • Slower pulls • Longer deployments • Bigger attack surface Smaller images. Faster deployments. Cleaner builds. Are you disabling pip cache in your Dockerfiles? #Docker #DevOps #Python #ContainerSecurity #CodeQuality #Codeac

Stop Deleting Virtual Environments! Just stop! Ever been burned by deleting a Python virtual environment and losing hours-worth of installed packages — all because your system Python version got bumped? 😩 That annoying moment when you activate an old venv only to watch your dependencies disappear is a rite of passage for many Python devs. What if I told you there’s a better way than mindlessly nuking environments and fighting slow package installs every time Python updates? In my latest article, I break down why this happens, how traditional workflows fall short, and what real tools like pyEnv (and even the blazing-fast uv) can do to keep your environments intact and your productivity flowing. 👉 If you’ve ever wasted time rebuilding environments, wrestling with pip, or simply wondered if there’s a smarter workflow, this one’s for you. Check it out & let’s make virtual environments something you manage, not something that manages you. 💡 🔗 Read here: https://lnkd.in/gayQD2ai
