Dockerfile

### **** This is the Build Image ****
FROM node:10.15.3

# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Followed this repo:

# to setup Docker + Lerna monorepo approach

# Copy monorepo setup files
COPY package.json yarn.lock lerna.json /usr/src/app/

# Copy packages used by dependencies
COPY ./packages/babel/package.json /usr/src/app/packages/babel/package.json
COPY ./packages/api/package.json /usr/src/app/packages/api/package.json
COPY ./packages/common/package.json /usr/src/app/packages/common/package.json

RUN yarn install --frozen-lockfile

# Bundle app source
COPY . /usr/src/app
RUN yarn workspace @entria/api build
RUN yarn workspace @entria/common build

EXPOSE ${SERVER_PORT}

I think something like that is better because you will make a smaller image with multi-stage

# base
FROM node:10.15.3-alpine as base
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COP package.json yarn.lock lerna.json /usr/src/app/
COPY ./packages/babel/package.json /usr/src/app/packages/babel/package.json
COPY ./packages/api/package.json /usr/src/app/packages/api/package.json
COPY ./packages/common/package.json /usr/src/app/packages/common/package.json

# dependencies
FROM base as dependencies
RUN yarn install --frozen-lockfile

# package
FROM base as package
COPY . /usr/src/app
RUN yarn workspace @entria/api build
RUN yarn workspace @entria/common build

EXPOSE ${SERVER_PORT}

you can use that as well

RUN yarn --pure-lockfile && \
    yarn cache clean

we can go even further

• yarn autoclean
• node-prune
• use webpack tree shaking to build server

Or use zeit ncc to build server
