DockerRoot running on xhyve hypervisor

This is a toolbox to run DockerRoot on xhyve hypervisor easily.

For VirtualBox or QEMU, see https://github.com/ailispaw/docker-root-packer.

Features

DockerRoot
Disable TLS
Expose the official IANA registered Docker port 2375
Support NFS synced folder: $HOME is NFS-mounted on the DockerRoot VM.

Requirements

xhyve
- Mac OS X Yosemite 10.10.3 or later
- A 2010 or later Mac (i.e. a CPU that supports EPT)

Caution

Kernel Panic will occur on booting, if VirtualBox (< v5.0) has run before.
Pay attention to exposing the port 2375 without TLS, as you see the features.

Installing xhyve

$ git clone https://github.com/mist64/xhyve
$ cd xhyve
$ make
$ cp build/xhyve /usr/local/bin/    # You may require sudo

$ brew install xhyve

Setting up DockerRoot images and tools

$ git clone https://github.com/ailispaw/docker-root-xhyve
$ cd docker-root-xhyve
$ make init

Booting Up

$ sudo ./xhyverun.sh [<dir>]

Welcome to DockerRoot docker-root /dev/ttyS0
docker-root login:

$ [SHARED_FOLDER=<dir>] make up    # You may be asked for your sudo password
Booting up...

On Terminal.app: This will open a new window, then you will see in the window as below.
On iTerm.app: This will split the current window, then you will see in the bottom pane as below.

Welcome to DockerRoot docker-root /dev/ttyS0
docker-root login:

Logging In

ID: docker
Password: docker (in most instances you will not be prompted for a password)

$ make ssh
docker-root-xhyve: running on 192.168.64.2
docker@192.168.64.2's password: 
Welcome to DockerRoot version 1.3.10, Docker version 1.9.1, build 66c06d0-stripped
[docker@docker-root ~]$

Shutting Down

Use halt command to shut down in the VM:

[docker@docker-root ~]$ sudo halt
halt[316]: Stopping Docker daemon
docker[320]: Loading /var/lib/docker-root/profile
docker[320]: Stopping Docker daemon
halt[316]: Executing shutdown scripts in /etc/init.d
Stopping crond... OK
Stopping sshd... OK
Saving random seed... done.
halt[316]: halt
[docker@docker-root ~]$ reboot: System halted
$

or, use make halt on the host:

$ make halt
docker-root-xhyve: running on 192.168.64.2
docker@192.168.64.2's password:
halt[317]: Stopping Docker daemon
docker[321]: Loading /var/lib/docker-root/profile
docker[321]: Stopping Docker daemon
halt[317]: Executing shutdown scripts in /etc/init.d
Stopping crond... OK
Stopping sshd... OK
Saving random seed... done.
halt[317]: halt
Connection to 192.168.64.2 closed by remote host.
Shutting down...

Using Docker

You can simply run Docker within the VM. However, if you install the Docker client on the host, you can use Docker commands natively on the host Mac. Install the Docker client as follows:

$ curl -L https://get.docker.com/builds/Darwin/x86_64/docker-latest -o docker
$ chmod +x docker
$ mv docker /usr/local/bin/    # You may require sudo

Alternatively install with Homebrew:

$ brew install docker

Then, in the VM, or on the host if you have installed the Docker client:

$ make env
docker-root-xhyve: running on 192.168.64.2
export DOCKER_HOST=tcp://192.168.64.2:2375;
unset DOCKER_CERT_PATH;
unset DOCKER_TLS_VERIFY;
$ eval $(make env)
docker-root-xhyve: running on 192.168.64.2

Upgrading DockerRoot

When DockerRoot is upgraded and docker-root-xhyve is updated,

$ git pull origin master
$ make upgrade
$ make up
$ make ssh
[docker@docker-root ~]$ sudo cp /var/lib/docker-root/start.sh /var/lib/docker-root/start.old
[docker@docker-root ~]$ sudo wget -qO /var/lib/docker-root/start.sh https://raw.githubusercontent.com/ailispaw/docker-root-xhyve/master/contrib/configs/start.sh
[docker@docker-root ~]$ sudo chmod +x /var/lib/docker-root/start.sh
[docker@docker-root ~]$ sudo reboot
