I just got a trial BlueMix account from IBM. I will begin to play with it. I like to map out such efforts in a special shell solution which I call sbshell. Generally, I iterate between the shell and editor to begin to create a functional library. In many cases, shell will not be part of the final solution, but it gives me a good place to start and allows me to quickly turn incidents and problems into working prototypes.

This creates an initial set of bash library files named ‘bluemix’, the first is local to my user, and the second is global. Both libraries are sourced into the environment after each save. I will then create a bluemix function that will run successfully, but will just ssh into my remote instance by default. In it I will store everything that I know about bluemix and begin to add functionality. It is like a scratchpad that becomes a launchpad.
#!/bin/bash
-() { return; }
---() { return; }
bluemix() {
--- bluemix
- Image ID:c3432649-385b-4b7a-909d-80ba79d5e84b
- flavor ID:1
ssh linux1@148.100.5.125
}
The build just finished a new instance that I created, so I grabbed a bit of information that might be useful later and set up my ssh keys.

So now I have a pretty basic Jailshell to begin working from and some rough documentation of what I did. If come back and structure the
lines that start with ‘-‘ a bit better, then I can overload the – function to act in certain ways, the following line could be caused to execute a curl against the api, if I were to be allowed access to imageId. What is nice is that I don’t have to fully define that functionality right now.

This way of thinking and coding is to supplement work in other languages, such as Nodejs or python and make Enterprise level connections which can be, for instance, scripted in conjunction with an ansible hostlist.
Enterprise DevOps (like System Administration) is often done it tiny burst between meetings or incidents, and I may work on something one day and not look at it again for two weeks. These conventions may seem trivial, but over time I am able to keep track of many different projects.
[ note: I recommend getting a free trial of bluemix, it was easy to configure and get to a point where docker was installed and available. ]
