Getting up and running with Docker

docker-tips.md

1. Make sure you have Docker toolbox installed:

https://docs.docker.com/mac/step_one/

2. Open Docker Quickstart Terminal in the launchpad!

3. Build the container:

• $ docker-compose build
• $ docker-compose up
• More info: docker-compose up

Should only have to do this whenever starting up the VM or dockerfile has changed.

4. Probably will have to set the docker port and host port to be the same so can boot up and access it locally:

• Open VirtualBox
• Open Settings
• Open Network
• Open Port Forwarding
• Click Add icon
• name: rails (or whatever), host port: 3000, guest port: 3000
• Open localhost:3000 in browser, should see the app working now!

5. If not working, try:

• $ docker-machine restart default
• $ eval $(docker-machine env default)

6. Issues with default virtual machine?

• Open VirtualBox
• Turn off the "default" machine
• Run Docker Quickstart and it starts up the VM and connects fine!

7. After all this is setup, this is all that's needed to start this project:

• Launch Docker Quickstart
• $ eval $(docker-machine env default)
• docker-compose up

8. Other tips:

• To run rails console: $ docker-compose run web rails console
• To see all the containers that are currently running: $ docker ps
