Barge running on xhyve hypervisor

This is a toolbox to run Barge OS on xhyve hypervisor easily.

For VirtualBox or QEMU, see https://github.com/bargees/barge-packer.

Features

• Barge OS
• Disable TLS
• Expose the official IANA registered Docker port 2375
• Support NFS synced folder: $HOME is NFS-mounted on the Barge 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

or

$ brew install xhyve

Setting up Barge images and tools

$ git clone https://github.com/bargees/barge-xhyve
$ cd barge-xhyve
$ make init

Booting Up

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

Welcome to Barge barge /dev/ttyS0
barge login: 

or

$ [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 Barge barge /dev/ttyS0
barge login: 

Logging In

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

$ make ssh
barge-xhyve: running on 192.168.64.2
bargee@192.168.64.2's password: 
Welcome to Barge 2.15.0, Docker version 1.10.3, build 662b14f
[bargee@barge ~]$ 

Shutting Down

Use halt command to shut down in the VM:

[bargee@barge ~]$ sudo halt
halt[341]: Executing shutdown scripts in /etc/init.d
Stopping crond... OK
docker[349]: Loading /etc/default/docker
docker[349]: Stopping Docker daemon
Stopping sshd... OK
Stopping haveged: stopped /usr/sbin/haveged (pid 108 106)
OK
Saving random seed: OK
halt[341]: halt
[bargee@barge ~]$ Connection to 192.168.64.2 closed by remote host.
$ 

or, use make halt on the host:

$ make halt
barge-xhyve: running on 192.168.64.2
bargee@192.168.64.2's password:
halt[347]: Executing shutdown scripts in /etc/init.d
Stopping crond... OK
docker[355]: Loading /etc/default/docker
docker[355]: Stopping Docker daemon
Stopping sshd... OK
Stopping haveged: stopped /usr/sbin/haveged (pid 108 106)
OK
Saving random seed: OK
halt[347]: halt

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
barge-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)
barge-xhyve: running on 192.168.64.2

Upgrading Barge

When Barge is upgraded and barge-xhyve is updated,

$ git pull origin master
$ make upgrade
$ make up
$ make ssh
[bargee@barge ~]$ sudo cp /etc/init.d/start.sh /etc/init.d/start.old
[bargee@barge ~]$ sudo wget -qO /etc/init.d/start.sh https://raw.githubusercontent.com/bargees/barge-xhyve/master/contrib/configs/start.sh
[bargee@barge ~]$ sudo chmod +x /etc/init.d/start.sh
[bargee@barge ~]$ sudo reboot
