I have the following project structure

• client folder
  • package.json
  • Dockerfile
• server folder
  • package.json
  • Dockerfile

client needs a npm run devserver command and server needs a npm run develop command. Both these commands simultaneously in 2 different terminals runs application in my local

The client folder uses some files which are present in server folder while running the devserver command. Now if I create separate dockerfiles in client and server folder. The devserver command wont be able to access files in server folder. And hence Im unable to start my application.

Is there any way I can access the files using dockerisation ? Maybe using docker-compose too not able to figure out.

You can put docker-compose.yaml in the same folder of server and client, and specify build context as ., while afford an additional dockerfile option to meet your requirement, example as next:

structure:

root@pie:~/20221015# tree
.
├── client
│   └── Dockerfile
├── docker-compose.yaml
└── server
    └── file_in_server
    └── Dockerfile
       
2 directories, 4 files

docker-compose.yaml:

version: "3.7"

services:
  client:
    image: client_image
    build:
      context: .
      dockerfile: client/Dockerfile

client Dockerfile:

FROM alpine
COPY server/file_in_server /tmp

execution:

root@pie:~/20221015# docker-compose build --no-cache
Building client
Step 1/2 : FROM alpine
 ---> 9c6f07244728
Step 2/2 : COPY server/file_in_server /tmp
 ---> c5cc162bad75

Successfully built c5cc162bad75
Successfully tagged client_image:latest
root@pie:~/20221015# docker run --rm -it client_image ls /tmp/file_in_server
/tmp/file_in_server

You could see the client dockerfile successfully access the file in server folder, you can move to build-definition if you want to dig more.
