The "hidden" complexity of Docker .env files 🐳 Production systems fail on the smallest details. Here are the edge cases that catch most developers: 🔹'$' needs doubling in 𝗰𝗼𝗺𝗽𝗼𝘀𝗲: password$$ → password$$$$ 🔹Never quote IPs/domains (quotes become part of value) 🔹Quote # passwords (or treated as comment) 🔹Space Management: Strings with spaces? Wrap them in quotes to ensure the shell parses them as a single unit. #Docker #Python #DevOps #SoftwareEngineering #FullStack

PyInfra Promotes Python Over YAML for Infrastructure Code 📌 PyInfra introduces a fresh approach to infrastructure management by using Python instead of YAML, offering greater flexibility and power. Developers can now write clean, functional code for declarative operations, avoiding YAML's pitfalls. With performance claims up to 10x faster than Ansible, it's a compelling choice for modern DevOps workflows. 🔗 Read more: https://lnkd.in/dxXZJF9X #Pyinfra #Python #Infrastructurecode #Yaml #Iac

Hurray!!!🥳 I built a broken API It's a little downing, not that I expected to build a project management API from scratch without encountering errors, just ... Just the deadline is past for a long time now and I am now relearning all the concepts from start and reading documentations🥲 But honestly as I go over, the murky concepts are appearing clearer now. I am understanding better how models, views, and urls work to bring to life a functional #Django API. Moving on to DRF and using serialisers. No rush. I may fail the course but I would have a better understanding. The obstacle is the way, right?😅 #Python #DoHardThings #ALX_BE

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

Really great post by Python Snacks that discusses the use of Depot, which is a framework that speeds up your builds compared to the usual Docker setup that most of us are used to. The thing that really caught my attention was, with a setup the author used, they saw a speedup of 33.94% compared to Docker! Incredible! The benefits, while great for people doing solo development, really seem to compound when looked at in a team setting. If someone on your team builds with Depot, the rest of the group can skip that build process, due to the fact that Depot caches that build on their server! If you weren't already sold, it can work as a drop-in replacement in Docker and CI workflows. #Python #PythonSnacks #Depot #Docker #DevOps #CICD #CI #CD #BuildTools #BuildAutomation #SoftwareEngineering #DeveloperExperience #DX #DeveloperTools #Infrastructure #CloudNative #Containers #Containerization #Kubernetes #PlatformEngineering #MLOps #Automation #EngineeringProductivity #Caching #BuildCaching #RemoteCaching #BuildAcceleration #Performance #DeveloperProductivity #TeamCollaboration #DevWorkflow #ComputerScience
