BOSH command line interface cheatsheet

Introduction

BOSH is a powerful tool to install and manage your deployments. You can find docs on https://bosh.io/docs. Consider using bosh-init tool to install to a cloud of your choice MicroBOSH instance (MicroBOSH is a single VM BOSH installation, it has everything that you need to deploy and manage).

Installing of BOSH CLI

BOSH command line interface is implemented as a ruby gem and can be run on every platform that supports ruby, you'll need to have ruby 2.1.x or higher to run it. To install it you can run gem install bosh_cli and gem update bosh_cli to update to a newer version.

Principles of Adult Behavior

Be patient. No matter what.
Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
Never assume the motives of others are, to them, less noble than yours are to you.
Expand your sense of the possible.
Don’t trouble yourself with matters you truly cannot change.
Expect no more of anyone than you can deliver yourself.
Tolerate ambiguity.
Laugh at yourself frequently.

"Multiple App Ports" Demo on Cloud Foundry

2017.03.29

These demos are validated against:

macOS is a Unix, and not built on Linux.

I think most of us realize that macOS isn't a Linux OS, but what that also means is that instead of shipping with the GNU flavor of command line tools, it ships with the FreeBSD flavor. As such, writing shell scripts which can work across both platforms can sometimes be challenging.

Homebrew

Homebrew can be used to install the GNU versions of tools onto your Mac, but they are all prefixed with "g" by default.

All commands have been installed with the prefix "g". If you need to use these commands with their normal names, you can add a "gnubin" directory to your PATH from your bashrc.
