My Boot2Docker — Zsh (+prezto) + Tmux inside Boot2Docker plus DockerCompose

myboot2docker is my configuration for boot2docker, currently it include(s): tmux, docker-compose, prezto the configuration framework for Zsh (like oh my zsh do).

Tools of the trade

• tmux 2.1
• docker-compose 1.6.0
• zsh 5.0.8 + prezto (OMZ)
• zsh completions for docker and docker-compose

Demo in Mac & Demo in PuTTY & Complete Demo

Installation

My Boot2Docker will work with any recent release of Boot2Docker version: v1.6.x, v1.7.x & v1.8.x

1. Launch Boot2Docker & Login as docker:

   boot2docker up boot2docker ssh

2. Clone the repository:

   for boot2docker version 1.7.x & 1.8.x:

   sudo -i curl -L https://raw.github.com/wharsojo/myboot2docker/master/tools/install.sh | sh

   for boot2docker version 1.6.x:

   sudo -i curl -L https://raw.github.com/wharsojo/myboot2docker/b2d-v1.6.x/tools/install.sh | sh

3. Reboot Boot2Docker and see the difference:

   sudo reboot boot2docker ssh

UnInstall

type: myboot2docker_uninstall

Docker Registry

Run registry server with data save on: /mnt/sda1/registry:

    $ boot2docker ssh
    $ sudo mkdir /mnt/sda1/registry
    $ sudo chown docker:staff /mnt/sda1/registry
    $ docker run -p 5000:5000 -v /mnt/sda1/registry:/tmp/registry -e GUNICORN_OPTS='["--preload"]' --restart=always --name=registry registry

Save container "hello-world" to private registry:

    $ docker pull hello-world
    $ docker tag  hello-world localhub:5000/hello-world
    $ docker push localhub:5000/hello-world

pull "hello-world" from private registry:

    $ docker pull localhub:5000/hello-world

run container:

    $ docker run localhub:5000/hello-world

List all container on private registry:

    $ curl -X GET http://localhub:5000/v1/search

Delete container library from private registry:

    $ curl -X DELETE http://localhub:5000/v1/repositories/library/hello-world/

Make private registry accessible to other computer

Create port mapping from boot2docker to the host:

    $ VBoxManage controlvm "boot2docker-vm" natpf1 "registry,tcp,,5000,,5000";

check your ip-address (ex: 192.168.1.2).

Assume that other computer are using boot2docker and myboot2docker, update "/etc/hosts" file inside boot2docker VM to reflect your ip-address:

    $ boot2docker ssh
    $ sudo vi /etc/hosts

    192.168.1.2  localhub

    $ sudo reboot

From other computer, please try to access the private-registry, like mentioned in section "Docker Registry"

Change PORT of Running Container

Switching port for Running Container, usefull if you have Java code connect to specific port and want to switch container. Example below for PORT: 15210 switch to 2(two) different container

Command: p-map

    ~ $ p-map
    Change port of running container
    Command: p-map <container_name> <host_port:guest_port>
