# Download this repo
$ git clone swiftwater_dev.git

# Go into the folder
$ cd swiftwater_dev

# Setup dev box
$ vagrant up

# Log into dev box
$ vagrant ssh

# After following "Post-install modifications" run the following
vagrant: $ su root
# Enter `vagrant` as password for `root`
root: $ docker-compose up

Synced folder resides at: /vagrant

• Vagrant will rsync all files/folders where the Vagrantfile is located to this folder

Recommended to create a folder called apps in this folder as it is already added to .gitignore that will sync to the VM. Store your repos or other items here.

• If you create an apps folder here, you can find it at /vagrant/apps

All commands should be run from root user.

Assumes you have a Dockerfile in your current folder

• Build an image (current directory)
  • $ docker build -t <tag_name> .
• Run a container (an instance of an image)

$ docker run -it --rm tag_name/imageID COMMAND

• Run multi-containers with docker-compose

If you need root priveleges, the password for root is vagrant.

If you need to use a RDBMS you'll need to modify PostgreSQL for a new user and allow connections via passwords

First get switch to user root

$ su root

Then switch to user postgres

$ su postgres

Create user in PostgreSQL with root with a password

bash-4.2$ createuser --superuser --pwprompt root

# Type password, then exit to switch back to vagrant user

Setup database

$ rake db:setup

• For production, run only bootstrap.sh
