# install node.js
FROM node:10.15.3

# create necessary directories and
# permissions
RUN mkdir -p /home/node/truckpeserver/node_modules && chown -R node:node /home/node/truckpeserver

# switch to working directory
WORKDIR /home/node/truckpeserver

# copy package.json files in directory
COPY package*.json ./

# check and switch to node user.
USER node

# install node_modules.
RUN npm install

# remove duplicate packages
RUN npm dedupe

# copy project files.
COPY --chown=node:node . .

# build server
RUN npm run build

# start server
CMD ["npm", "start"]

What I have tried already.

1. Linking
2. Creating a network: bridge

Everything fails and prisma is not working please help

Answer 1

Remove linking any another configuration regarding network as docker-compose will take care of it. in service to service communication, you can use container name to do some call from one container to another.

Now the error is from your truckpeserver container,

truckpeserver | FetchError: request to http://localhost:4466/ failed, reason: connect ECONNREFUSED 127.0.0.1:4466

all you need to change localhost to prisma:4466 . when you use localhost in some container it will point localhost of that container, you can not access other container using localhost.

From the error logs, it seems you are using cross-fetch? then you can try something like

fetch('//prisma:4466')
  .then(res => {
    if (res.status >= 400) {
      throw new Error("Bad response from server");
    }
    return res.json();
  })
