Build with Docker

Hi, We're trying to set this up within our CI system by creating an image which contains just the build tool, so a subsequent CI step can run the image using a volume containing our code.

Whenever we run yarn we receive a number of warnings such as these:

[1/4] Resolving packages... [2/4] Fetching packages... info fsevents@1.2.4: The platform "linux" is incompatible with this module. info "fsevents@1.2.4" is an optional dependency and failed compatibility check.

Do you use Docker for development at all, and if so do you have a working Dockerfile which you could share? Thanks

I only use docker for build and run the prod version. Here is mine dockerfile:

FROM node:10.15.3 as source
WORKDIR /src/progression-framework
COPY package.json ./
RUN npm install
COPY . ./
RUN rm -rf node_modules/sharp
RUN npm install --arch=x64 --platform=linux --target=10.15.3 sharp
RUN npm run build

• I add gatsby-cli to dependencies (package.json)

The error caused by the sharp module. This version only runs at Windows OS. Need to change a linux specific one.

Some other dependencies need to update to a fresher version, that's why the many warnings, but the application still runs with these.
