Three ways to copy and share data to a Docker container:

1. Providing data on build time: Docker ADD vs COPY

2. Providing data on run time: How to copy files to or from a Docker container

3. Sharing data via volumes: Using volumes in Docker Compose

Simplified OAuth 2 workflow for dummies (me!)

User case

A user wants profile data from an app.

Workflow

1. User makes a request to a client (website, mobile app, etc).
2. Client (may) redirect the user to auth server login form.
3. User logs into the auth server.
4. Auth server validates previous credentials and returns an access token to the client.

$ docker run --rm --name my-mongo -it -p 27017:27017 mongo:3.2.7 
# or as a daemon
$ docker run --name my-mongo -d mongo:3.2.7

# connect to the previous container.. with another container
$ docker run -it --link my-mongo:mongo --rm mongo:3.2.7 sh -c 'exec mongo "$MONGO_PORT_27017_TCP_ADDR:$MONGO_PORT_27017_TCP_PORT/test"'
