One week into my Docker/K8s journey: ✅Dockerized MERN app ✅Basic docker-compose setup ✅First pod running in minikube ❌Still confused about Services vs Ingress Progress feels good!#100DaysOfCloud
Kubernetes networking question: My frontend pod needs to talk to my backend pod. Do I use: · ClusterIP Service? · Ingress? · Something else? What's the simplest way for development? #KubernetesHelp#CKAD
Was trying to access my Dockerized React app on localhost:3000 but got nothing. Forgot port mapping! docker run -p 3000:3000 my-react-app The syntax:-p host-port:container-port Simple but crucial!#Docker
Made a classic Docker mistake: COPY . . RUN npm install This breaks caching!Docker reinstalls dependencies on every code change. Correct order: COPY package.json . RUN npm install COPY . . Now dependencies only reinstall if package.json changes
Kubernetes YAML files look scary at first. But it's just telling the system: · Here's my app (Deployment) · Here's how to access it (Service) · Here's my config (ConfigMap) Breaking it down makes it manageable. #Kubernetes
Trying to run PostgreSQL in Docker for my MERN app: docker run -e POSTGRES_PASSWORD=mysecretpassword postgres But how do I persist data when container restarts? Learning about Docker volumes next... #PostgreSQL#Docker
Docker doesn't read your.env files automatically. Had to learn: 1. Copy .env in Dockerfile 2. Or use docker-compose env_file 3. Or Kubernetes Secrets Simple things that waste hours! #Docker
Installed minikube and ran my first pod today. The magic moment:kubectl get pods actually showed something running. Then immediately broke it trying to connect to my database😅 Learning:Pods need Services to talk to each other. #Kubernetes#CKAD
Just learned why Docker layer caching matters: Changed one line in my React component→ entire node_modules reinstalled 😠 Fixed:Separate COPY commands COPY package.json . RUN npm install COPY . . Now code changes are instant⚡️ #DockerTips
