Im fairly new to Docker and am trying to get my create-react-app in my GitHub repo to work with Docker Cloud, its connecting and updating successfuly but the image does not seem to update.
Ive made and account and linked the repos in both Docker Hub and Docker Cloud.
When i do a git push command in my project to my repo, it successfully starts an autobuild on both Docker Cloud and Docker Hub, which both complete successfuly.
When i start up Kitematic and create a container with my image, i get back the original image, without the changes to the code.
Is this a caching issue with the build process or have i missed out a crucial step somewhere?
The Dockerfile is
FROM node:8.9.4
ENV NPM_CONFIG_LOGLEVEL warn
ARG app_env
ENV APP_ENV $app_env
RUN mkdir -p /frontend
COPY ./ ./frontend
WORKDIR /frontend
VOLUME /var/lib/data
RUN yarn && yarn cache clean
EXPOSE 3000
CMD [ "yarn", "start" ]
