I am currently new to Docker and in the process of dockerizing some applications.
The project structure consists of:
-PlayProject
-------app
----------controllers
----------models
----------views
-------ci
-------conf
-------project
-------public
----------css
----------js
----------img
----------fonts
-------sbt-cache
-------src
-------target
-------front
------------header (npm folder)
------------footer (npm folder)
-------Dockerfile
----*
This project utilizes PlayFramework on the backend with sbt as the build tool, and Reactjs on the frontend. The frontend is composed of two modules - header and footer.
In my Dockerfile, I need to build the frontend modules by running 'npm run build' commands in both header and footer folders to update the public folder before containerizing.
My Dockerfile :
FROM openjdk:8
ENV HEADER front/header
ENV FOOTER front/footer
ENV PROJECT_HOME /usr/src
ENV SBT_VERSION 1.2.1
#install node

curl -sL https://deb.nodesource.com/setup_4.x | bash && \
# install node
apt-get update && \
apt-get install nodejs && \
# confirm successful installation
node -v && \
# npm installs automatically
npm -v
WORKDIR $HEADER/
RUN \
echo $(ls -1 $HEADER/) && \
npm cache clean && \
npm i && \
npm run build
WORKDIR $FOOTER/
RUN \
echo $(ls -1 $FOOTER/) && \
npm cache clean && \
npm i && \
npm run build
RUN mkdir -p $PROJECT_HOME/sbt $PROJECT_HOME/app
WORKDIR $PROJECT_HOME/sbt
# Install curl
RUN \
apt-get update && \
apt-get -y install curl && \
apt-get -y install vim
# Install sbt
RUN \
curl -L -o sbt-$SBT_VERSION.deb https://dl.bintray.com/sbt/debian/sbt-$SBT_VERSION.deb && \
dpkg -i sbt-$SBT_VERSION.deb && \
rm sbt-$SBT_VERSION.deb && \
apt-get update && \
apt-get -y install sbt
COPY . $PROJECT_HOME/app
WORKDIR $PROJECT_HOME/app
EXPOSE 9000
I am facing an issue where I am unable to locate the frontend folders and execute my npm commands. Any suggestions on what could be the problem?
