Tip from one writer to another: Avoid abbreviations. At least, fully define them once, then abbreviate thereafter. I've read the whole post and still no idea what "CM" stands for.
Otherwise, it was a very interesting read. I've not had a need to manage more than a handful of containers, so it was good to hear about tips for managinging lots of them. ++
Thanks for the feedback :)
This wasn't written so much as collected from notes hence the general rough rambling presentation that assumes a certain background.
I've updated the post but for reference CM as used here is "Config Managament" (Chef, Puppet, Ansible etc).
