# vagrant virtualization of docker containers
The following describes the process of provisioning a local environment to run docker applications in a vm (vagrant) environment. This project documents the installation of virtualbox / vagrant and post installation of both docker and nodejs. We experiment with using nodejs to load up and run new docker images (outside of swarm/stacks) and investigate the level of monitoring and control available via docker. These tests were run against a linux mint 18.1 (Xenial) installation (Ubuntu 16.04 LTS) and trailed hashicorp/precise64, ubuntu/trusty64 and ubuntu/xenial64 vagrant boxes (images).
### install virtualbox / vagrant (host)
The following describes installing the vagrant / virtualbox on the host system.
source: https://www.godaddy.com/garage/tech/config/install-vagrant-ubuntu-14-04/
```
sudo apt-get install virtualbox
sudo apt-get install vagrant
```
### provision linux precise64 vm
The following with initialize a Vagrantfile in the current working directory. The for the purposes of this project,
we initialized with ```ubuntu/trusty64``` (ubuntu 14.04 LTS).
```bash
$ vagrant init hashicorp/precise64 # ubuntu 12.04 LTS (vagrant default)
$ vagrant init ubuntu/trusty64 # ubuntu 14.04 LTS (preference)
$ vagrant init ubuntu/xenial64 # ubuntu 16.04 LTS (some issues binding to ioctl)
$ vagrant up
```
note: if there is a problem with not being able to locate the virtual box provider, this is likely a version disparity between vagrant 1.8.x and virtualbox 5.1.x. You can try the following workaround to have vagrant resolve the appropriate version of virtualbox.

### vagrant cheatsheet
For reference.
```
Usage: vagrant [options] []
-v, --version Print the version and exit.
-h, --help Print this help.
Common commands:
box manages boxes: installation, removal, etc.
destroy stops and deletes all traces of the vagrant machine
global-status outputs status Vagrant environments for this user
halt stops the vagrant machine
help shows the help for a subcommand
init initializes a new Vagrant environment by creating a Vagrantfile
login log in to HashiCorp's Atlas
package packages a running vagrant environment into a box
plugin manages plugins: install, uninstall, update, etc.
port displays information about guest port mappings
powershell connects to machine via powershell remoting
provision provisions the vagrant machine
push deploys code in this environment to a configured destination
rdp connects to machine via RDP
reload restarts vagrant machine, loads new Vagrantfile configuration
resume resume a suspended vagrant machine
snapshot manages snapshots: saving, restoring, etc.
ssh connects to machine via SSH
ssh-config outputs OpenSSH valid configuration to connect to the machine
status outputs status of the vagrant machine
suspend suspends the machine
up starts and provisions the vagrant environment
version prints current and latest Vagrant version
```
### configuring virtualbox networking
The following configures the virtual box instance to run on 192.168.2.88 on the host machine.
```ruby
config.vm.network "public_network", ip: "192.168.2.88"
```
### post installation script
This repository comes with a additional ```bootstrap.sh``` file that installs nodejs and
docker-ce on the vm this can be configured with.
```ruby
config.vm.provision :shell, path: "bootstrap.sh"
```
### test installation
once installation has completed (following a vagrant up), then ```vagrant ssh``` into the vm and run the following.
```
sudo docker run hello-world
```
### docker cheatsheet
```
Usage: docker COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/home/vagrant/.docker")
-D, --debug Enable debug mode
--help Print usage
-H, --host list Daemon socket(s) to connect to
-l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info")
--tls Use TLS; implied by --tlsverify
--tlscacert string Trust certs signed only by this CA (default "/home/vagrant/.docker/ca.pem")
--tlscert string Path to TLS certificate file (default "/home/vagrant/.docker/cert.pem")
--tlskey string Path to TLS key file (default "/home/vagrant/.docker/key.pem")
--tlsverify Use TLS and verify the remote
-v, --version Print version information and quit
