Meteor-building and Sentry-uploading Dockerfile

Dockerfile

# --- Stage 1: build Meteor app and install its NPM dependencies ---

# Make sure both this and the FROM line further down match the
# version of Node expected by your version of Meteor -- see https://docs.meteor.com/changelog.html
FROM node:8.15.1 as builder

# METEOR_VERSION should match the version in your .meteor/release
# APP_SRC_FOLDER is path the your app code relative to this Dockerfile
# BUILD_SRC_FOLDER = /opt/src is where app code is copied into the container
# BUILD_OUTPUT_FOLDER = /opt/app is where app code is built within the container

# Note: the line above will show a warning about the --allow-superuser flag.
# You can safely ignore it, as it doesn't apply here. The server *is* being built, silently.
# If the process gets killed after awhile, it's probably because the Docker VM ran out of memory.
