🚀 DevOps & Deployment
From git push to live URL — Docker, Render, env vars, health checks.
5 concepts
1
Docker & Dockerfile
A Dockerfile describes how to build a reproducible image. Same image runs locally and in prod.
›
2
Render deployment
Connect a GitHub repo, Render builds the Docker image and runs it on a managed VM.
›
3
Environment variables
Config that changes between environments. Never hardcode secrets in source.
›
4
Health checks & observability
/health endpoint tells the load balancer 'am I alive?'. Log every request with timing.
›
5
Git workflow
Branch, commit, push, PR. Conventional commit messages keep history readable.
