MyOS - develop and share command line environments

Blog post about MyOS

High Level

Uses Docker + Docker Compose to provide a consistent and reproducible build environment. Base image assumes the minimum while still being useful out of the box.

Usage

Assumptions

Everything depends on myos base Docker image. This image is available on Dockerhub, but you may also build it using the included Dockerfile.

The default docker-compose.yml mounts your hosts ~/.ssh/authorized_keys file into the running container. This is what allows the openSSH server to authenticate you when you connect. This means you will need an authorized_keys file in the correct location with any keys you want to be able to use.

Ctrl-D is the most sure fire way of getting out of the container

Setup

1. Install the CLI

$ npm install -g myos

1. Create a new template project

$ myos init ./template
$ cd template

1. Start the container

$ myos create fooName

1. Connect to the container

$ myos connect

Advanced usage

Assuming you've already installed the tool, my personal configuration can be used to test out MyOS.

1. Clone my personal MyOS config

$ git clone https://github.com/rylandg/rylandg-myosfiles

1. Create a MyOS based on my setup

$ cd rylandg-myosfiles
$ myos create rysetup
$ myos connect rysetup

API

Init

myos init <dir>

Creates the initial templates that the default docker-compose.yml expects. These are...

# vim
vim/binds.vim
vim/helpers.vim
vim/plugins.vim
vim/vimrc
# zsh
zsh/.zlogin
zsh/.zprofile
zsh/.zshenv
zsh/.zshrc
# tmux
tmux/tmux_saves
tmux/install_tmux.sh
tmux/tmux.conf

These files are empty (for the most part). You're expected to add your environment specific settings.

Create

myos create <name>

Runs docker-compose up -d from the current directory

Connect

myos connect

Connects to a previously created MyOS environment

Restart

myos restart <name>

Restart a previously created MyOS environment

Remove

myos remove <name>

Remove a running MyOS environment

Issues/planned changes

• Very vim focused, would like to see if its possible to support other editors (definitely Emacs)
• Needs CLI command that allows you to copy another users MyOS environment
• Multiple MyOS environments should be able to run simelataneously
• SSH key for authorized_keys could be autogenerated
• Potentially move away from NodeJS for CLI
