如何码头化 json-server？

Question

I'm trying to run json server with docker along with my application in react, but it's not working.

My dockerfile and compose settings:

FROM node:16-alpine
WORKDIR /app
COPY package*.json .
RUN npm install
COPY . .
EXPOSE 3000
CMD [ "npm", "run", "dev" ]

---

version: "3.7"
services:
    react:
        build: .
        ports:
            - 3000:3000

    json-server:
        build: .
        ports:
            - 4000:4000
        command: npm run server

when I run the command docker-compose up, my react application works but the json server shows this in the terminal:

frontend@0.0.0 server
json-server --watch ./db/dados.json --port 4000

\{^_^}/ hi!
Loading ./db/dados.json
Done

And nothing happens when I try to fetch the data.

Try adding --host flag in your json-server command

json-server --watch./db/dados.json --port 4000 --host 0.0.0.0
