webpack-dev-server inside docker trouble

I have a file structure like this:

/root-app
  /api
  /dashboard
    package.json
    yarn.lock
    Dockerfile
docker-compose.yml

/root-app/docker-compose.yml

dashboard:
  build: ./dashboard
  command: yarn dev
  volumes:
    - ./dashboard:/usr/src/app
    - /usr/src/app/node_modules

/root-app/dashboard/Dockerfile

FROM node
WORKDIR /usr/src/app
ADD package.json yarn.lock ./
RUN yarn install
COPY . .

When I run docker-compose up --build folder node_modules in /roor-app/dashboard it's created but it's empty. Why? I should have my node_modules for local development.

UPDATE 1

When I using absolute paths rather than relative paths

dashboard:
  build: ./dashboard
  command: yarn dev
  volumes:
    - ./dashboard:/usr/src/app
    - ./dashboard/node_modules:/usr/src/app/node_modules

I get this error:

dashboard | yarn run v1.3.2
dashboard | $ webpack-dev-server --mode development
dashboard | /bin/sh: 1: webpack-dev-server: not found
dashboard | error Command failed with exit code 127.

UPDATE 2

My new /dashboard/Dockerfile

FROM node
WORKDIR /usr/src/app
COPY package.json ./
COPY yarn.lock ./
RUN yarn install

and removed - ./hms-dashboard/node_modules:/usr/src/app/node_modules from docker-compose.yml, error from update-1 still here.

You could try installing on build currently running into an issue with exit code 0, but the node_modules will install. I had an issue where the devDependencies where not installing with yarn.

FROM node
ARG environment=development

RUN mkdir /client

WORKDIR /client
COPY . /client

EXPOSE 8080

RUN npm --version
RUN npm install yarn
CMD if ["$environment" = "development"]; then yarn install --production=false; else yarn install; fi
RUN echo $environment
CMD if [ "$environment" = "development" ] ; then yarn build && yarn start; else yarn build; fi

In your /root-app/dashboard/Dockerfile remove copy command as you are already binding the same directory using volume.

Also use COPY instead of ADD command in Dockerfile.

COPY package.json ./
COPY yarn.lock ./

In docker-compose.yml remove the second volume
- ./dashboard/node_modules:/usr/src/app/node_modules , As first directory (./dashboard) is already mounted (/usr/src/app/).

Let me see your output after these updates.
