How to access containers in EC2?-CodePudding

I try to deploy a NodeJS (NestJS) application on Ec2 instance, so I create Ec2 instance and connect to them via ssh, install Git, Node, Docker, Docker-compose etc. When I run only nest start to run my node.js app then everything is fine and I see my app from the browser (but only when I set MyIP in inbound rules, why? - I've had also all Http/Https rules...).

But I can't do this in this way because I have to use docker-compose with two services - Api and Redis.

my docker-compose looks like here:

version: '3.7'

networks:
  proxy:
    name: proxy

services:
  redis:
    image: redis:6.2-alpine
    ports:
      - 6379:6379
    command: ["redis-server", "--requirepass", "redisPass12345!"]
    networks: 
      - proxy

  worker:
    container_name: worker
    build:
      context: .
      dockerfile: Dockerfile
    depends_on:
      - redis
    ports:
      - 8080:8080
    expose: 
      - '8080'
      - '3005'
    env_file:
      - .env
    volumes:
      - .:/usr/src/app
      - /usr/src/app/node_modules
    command: npm run dev
    networks:
      - proxy

When I build and up docker-compose with:

sudo docker-compose up

and open browser then I see that this site cannot be reached... Can someone tell me what have i doing wrong?

here is also my Dockerfile:

FROM node:16.3.0-alpine as builder

WORKDIR /dist

COPY package*.json ./
RUN npm install --force

COPY . .
RUN  npm run build

EXPOSE 8080

CMD [ "npm", "run", "dev"]

and Inbound rules:

PS. One more thing, my process.env.PORT is set to 3005.

CodePudding user response：

If your application is listening on port 3005, you should expose this port also in your docker-compose.yaml, and also in the AWS inbound rules.

Try to docker ps to and see which port at exposed for your nodejs application.
