Issue
Hi Dockerized a reactjs and expressjs project, everything is worked good when i have written separate docker compose file.
But now i written one compose file
docker-compose-all-dev.yml file
version: '3.7'
services:
client:
container_name: react-dev
build:
context: ./client
dockerfile: Dockerfile.react-dev
ports:
- 3000:3000
server:
container_name: server-dev
build:
context: ./server
dockerfile: Dockerfile.server-dev
ports:
- 5000:5000
Now it’s running client server only, why not running backend server?
But it works when i run it in two different files like this.
docker-compose-client.yml file:
version: '3.7'
services:
client:
container_name: react-dev
build:
context: ./client
dockerfile: Dockerfile.react-dev
ports:
- 3000:3000
and docker-compose-server.yml file
version: '3.7'
services:
server:
container_name: server-dev
build:
context: ./server
dockerfile: Dockerfile.server-dev
ports:
- 5000:5000
Can anyone tell me what is the possible issue of not running the both app when i run in one compose file? how can i solve it?
For your reference.
My Dockerfile-server-dev file
FROM node:14
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 8080
CMD [ "node", "server.js" ]
and my Dockerfile.react-dev file
FROM node:14.1-alpine as build
WORKDIR /app
COPY . /app
ENV PATH /app/node_modules/.bin:$PATH
RUN yarn config delete proxy
Run npm config rm proxy
RUN npm config rm https-proxy
RUN npm install
RUN npm start
I dont know what is the issue actually running two development server in one docker-compose file
Solution
There are at least few problems, your Dockerfile.react-dev is missing entrypoint and CMD parts, you should not start your server with RUN clause. Instead use Entrypoint and possibly CMD for starting it. Another problem is, that you are exposing different port on Dockerfile-server-dev than on your compose file.
