node.dockerfile

# Build: docker build -f node.dockerfile -t nodeapp .

# Option 1: Create a custom bridge network and add containers into it

# docker network create --driver bridge isolated_network
# docker run -d --net=isolated_network --name mongodb mongo

# NOTE: $(pwd) in the following line is for Mac and Linux. Use ${PWD} for Powershell. 
# See https://blog.codewithdan.com/docker-volumes-and-print-working-directory-pwd/ syntax examples.
# docker run -d --net=isolated_network --name nodeapp -p 3000:3000 -v $(pwd)/logs:/var/www/logs nodeapp

# Seed the database with sample database
# Run: docker exec nodeapp node dbSeeder.js

# Option 2 (Legacy Linking - this is the OLD way)
# Start MongoDB and Node (link Node to MongoDB container with legacy linking)
 
# docker run -d --name my-mongodb mongo
# docker run -d -p 3000:3000 --link my-mongodb:mongodb --name nodeapp danwahlin/nodeapp
