Managing OpenStack instances with Ansible through an SSH bastion host

I'm be using DreamCompute as my OpenStack provider, but there are dozens to choose from. I assume you already have Ansible and the OpenStack CLI tools installed.

Motivation

With the proliferation of OpenStack public clouds offering free and intro tiers, it's becoming very easy to effectively run a simple application for free or nearly free. Also with the emergence of Ansible, you don't need to learn and deploy complicated tools to do configuration management.

• Nodejs
• Gruntjs

Setup

unbracketed

Example: Moving up to a few commits to another branch

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout branch-B
git cherry-pick X
git cherry-pick Y

Mastery comes from a combination of at least several of the following:

Org Editing in haskell-mode

The video opens with a regular Haskell source file in haskell-mode. We start off by adding headings that break the file into meaningful chunks. A section heading is indicated by an asterisk following Haskell single-line comment characters, i.e. -- *. These are top-level headings, sub-headings are indicated by adding more asterisks.

These section markers are given meaning by
