I'm trying to Run Docker Compose with Docker on Google Cloud Platform

Question

I new to docker and GCP. I followed the instructions given here

My docker-compose.yml file looks like this:

version: '3'
services: 
  backend:
    image: com.xyz.backend:v1
    build: ./server/
    ports: 
      - "5000:5000"
    volumes:
      - ./server:/usr/src/app
      - /usr/src/app/node_modules
  frontend:
    image: com.xyz.frontend:v1
    build: ./client/
    ports:
      - "3000:3000"
    volumes:
      - ./client:/usr/src/app
      - /usr/src/app/node_modules
    links:
      - backend

Docker file => client/Dockerfile:

FROM node:8.15.0-alpine

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

ENV NODE_PATH=/node_modules

ENV PATH=$PATH:/node_modules/.bin

COPY package.json /usr/src/app

RUN npm i -g npm-check-updates

RUN ncu -u

RUN npm install

COPY . /usr/src/app

ENV PORT 3000

EXPOSE 3000

RUN pwd

CMD ["npm", "start"]

Docker file => server/Dockerfile

FROM node:8.15.0-alpine

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

ENV NODE_PATH=/node_modules

ENV PATH=$PATH:/node_modules/.bin

RUN npm install -g nodemon

COPY package.json /usr/src/app

RUN npm i -g npm-check-updates

RUN ncu -u

RUN npm install

COPY . /usr/src/app

ENV PORT 5000

EXPOSE 5000

RUN pwd

CMD ["npm", "start"]

cloudbuild.yaml

steps:
- name: ‘docker/compose:1.23.2’
  args: [‘up’, ‘-d’]
- name: 'gcr.io/cloud-builders/docker'
  args: ['tag', 'workspace_app:latest', 'gcr.io/$PROJECT_ID/$REPO_NAME:$COMMIT_SHA']
images: ['gcr.io/$PROJECT_ID/$REPO_NAME:$COMMIT_SHA']

Project Structure:

Project
↳ client
   ↳ Dockerfile
  server
   ↳ Dockerfile

  README.md
  Dockerfile
  cloudbuild.yaml
  docker-compose.yml

When I try to run this in gcp no errors are thrown but I couldn't access using the public ip.

When I'm running it locally it runs fine.

I run the docker using the following command

docker run     -v /var/run/docker.sock:/var/run/docker.sock     -v "$PWD:$PWD"     -w="$PWD"   docker/compose:1.23.2 up

I tried setting the port also like:

docker run     -v /var/run/docker.sock:/var/run/docker.sock     -v "$PWD:$PWD"     -w="$PWD"  -p 8080:3000   docker/compose:1.23.2 up

Couldn't find where the problem is. Please advice.. Thanks in advance.

It looks to me like a firewall issue.

The example you followed listens to connections on port 80 while your application uses port 3000 and 5000. GCP comes with a set of default firewall rules where ports for some standard protocols like HTTP are accessible, but you will need to create a new firewall to allow access for the relevant ports of your app.

Check out this answer about creating firewall rules for specific ports.
