# Create the app directory
RUN mkdir -p /app
RUN chown -R node:node /app

# The Docker node image includes a non-root user named 'node'.
# A recommended security practice is to avoid running containers as root, and
# to restrict capabilities within the container to only those required by the app.
# Therefore, we use the 'node' user to run the app.
USER node

# Switch to the app directory

# Copy in the NPM dependency files

# Install app dependencies
RUN yarn install --ignore-engines

# Copy in the src files
# Ideally we would want to delete src afterwards
# but this cannot be done in Docker and since
# this is a boilerplate
COPY ecosystem.config.js .
COPY src ./src

# Build and set production
RUN yarn build
ENV NODE_ENV production

# Launch it
