Issues with creating a docker container for react front end with yarn

Question

Context: I'm currently working on a project with a Java backend and React frontend. I am trying to get the react front end working in a docker container (it currently runs if I just run yarn start). I am writing a Dockerfile which I believe I would build to then provide an image that I can run.

I try to build the docker file using docker build ./ but run into the following in error:

My docker file is as follows:

FROM node:11.1.0-alpine AS node_base

FROM node_base as deps
WORKDIR /ProjectFrontEnd
COPY package.json .
COPY yarn.lock .
RUN yarn install

COPY . .

# FROM node_base as build
# WORKDIR /ProjectFrontEnd
# COPY --from=deps /ProjectFrontEnd/node_modules /ProjectFrontEnd/node_modules
# COPY . /ProjectFrontEnd
# Expose port
EXPOSE 3000

RUN yarn build

# FROM scratch AS ui
# COPY --from=build /ProjectFrontEnd/ /ProjectFrontEnd/

#start the app
CMD [ "yarn start" ]

I'm quite new to this but would appreciate any help/guidance. Thanks in advance.

Question answered by Brian Thompson in the comments. The error syntax made it unclear that it was referring to the version. I looked up the docker version and found the latest valid one which was 16.13.0 and used this.
