Day 2 of @Docker 🐳
Built my own #Dockerfile, created images, ran containers, and #deployed a Node app on #AWS EC2 🚀
From docker build to docker run -p 8000:8000 — things finally clicked.
Still breaking stuff, still learning. 💪

Stop shipping bloated Docker images!
A massive image slows down your CI/CD and eats up disk space.
Here are 3 quick wins to optimize your #Dockerfile:
Meet Docker Hub: Your go-to registry for Docker images! 🐳
It's where you can find, store, and share container images with the world (or just your team). Think of it as GitHub, but for Docker containers!
Makes collaboration and deployment a breeze.
#DockerHub
Pues toca hacer #Dockerfile antes de lo esperado.
La imagen de apache2 es "básica". Para poder habilitar ciertas cosas tengo que crear mi propia imagen #docker

Dockerfile rule:
Copy package.json FIRST.
Then install.
Then add source.
Speed matters.
#Docker #DevOps #Dockerfile #Containers #CICD #BuildOptimization #NodeJS #SRE #CloudComputing #100DaysOfDevOps #Infra
Layers make Docker powerful.
If package.json doesn't change, dependencies get cached.
Builds become faster.
#Docker #DevOps #Containers #Dockerfile #CICD #BuildOptimization #SRE #CloudComputing #100DaysOfDevOps #NodeJS #Infra
Common #Dockerfile mistakes:
➤Using latest tag → non-reproducible builds
➤ nstalling deps before copying package.* → no layer cache
➤ Leaving build tools in final image → bloated size
➤Missing .dockerignore → slow, heavy context
➤ Not using multi-stage builds

➤ Using latest tags
➤ Running as root
➤ Bloated images (no multi-stage builds
