BUILT Image (creo imagen usando dockerfile)

docker build –t klerith/cron-ticker:tigre

CONSTRUCCION multiples PLATAFORMAS

docker build --platform Linux/amd64,Linux/arm64,Linux/arm/v7 ^

-t klerith/cron-ticker:latest –push .

SUBIR IMAGEN a Dockerhub

docker image tag klerith/cron-ticket (por defecto es el latest)

docker image tag klerith/cron-ticket: pantera

BAJAR IMAGEN a Dockerhub

docker pull klerith/cron-ticket (por defecto es el latest)

docker pull klerith/cron-ticket: pantera

Plataforma de construccion (Arquitectura)

FROM --platform=linux/amd64 node:19.2-alpine3.16

FROM --platform=$BUILDPLATFORM node:19.2-alpine3.16 (utilize el buildx que cree)

Multi-Stage Build
Las creaciones (dependencias/test/build/run), divide el dockerfile en leyer/images-> “STAGES”.

Si cambia algo en alguno de los bloques. Ahí se ejecuta nuevamente ese bloque

COMO SE VE SIN Multi-Stage Build

#CREACION IMAGEN

# /app/usr/lib tiene una carpeta donde se guarda las info

# FROM node:19.2-alpine3.16
# FROM --platform=linux/amd64 node:19.2-alpine3.16
FROM --platform=$BUILDPLATFORM node:19.2-alpine3.16 (con buildx no se usa esta linea)

# cd app "me muevo de directorio a app"

WORKDIR /app

#copio de mi proyecto los archivos app y mis package.json

#COPY -archivos a copiar- | -ubicacion-
COPY app.js package.json ./

#instalo las DEP, puedo agregar mas -> && npm install
RUN npm install

# compio todos los archivos y lo pega en el WorkingDirctory

COPY . .

#Realizar el testing
RUN npm run test

#Eliminar archivos no necesarios en produccion

RUN rm -rf tests && rm -rf node_modules

#Instalo unicamente las DEP de produccion --

RUN npm install --prod

# Comado run de la imagen -npm run/start-

CMD [ "node","app.js" ]

#EN TERMINAL creo la imagen (docker build --tag cron-ticker .)

# . por que se ejecuta en la ubicacion donde esta el 'Dockerfile'
 COMO SE VE con Multi-Stage Build

Creo mi BUILDX y luego indico que lo voy a usar

docker buildx créate –name mybuilder –driver docker-container –bootstrap

docker buildx use mybuilder

docker build ls
