Cheat sheet: container images

A collection of container images I use for admin tasks or troubleshooting in environments such as CoreOS where quite often the one or other thing is not available or I can't be bothered to install stuff.

Networking

Good old netcat:

$ docker run -it --rm appropriate/nc $IP $PORT

Install VAMP and dependencies on DC/OS 1.8

Make sure the DC/OS CLI is installed. I'm using httpie here but curl also works ;)

Note that all you'll need locally is install-job.json, a DC/OS Jobs definition. So, to install VAMP 0.9 and dependencies, do the following:

# download the install job
$ http --download https://gist.githubusercontent.com/mhausenblas/bb967625088902874d631eaa502573cb/raw/ece1c702dede66693b4873985ef317c568384436/install-job.json

Why I prefer CLI over UI ?

• CLI tools are Composable using pipes (great old school example http://www.youtube.com/watch?v=tc4ROCJYbm0&t=5m32s)
• Great for automation and batch processing
• Fewer mouse clicks. Can go futher using only keyboard
• Avoid cluky UIs especially over poor connections
• I'm insulated from UI changes
• Easier to debug as they are often more verbose than the UI

The DC/OS CLI (https://dcos.io/docs/1.7/usage/cli/)

setup:  You have a multi-purpose cluster environment used for end user web traffic and in-house analytics.  In this example we have 4 running docker instances of nginx hosting our web application fronted by haproxy and 2 small and 2 medium instances of YARN running on Mapr Hadoop with MapRFS.

note: most organizations underutilize their datacenter resources by separating these two concerns.   In this demonstration we are co-locating these separate needs.
<setup scripts>
1. look at master port 80 (web app)
     - technical dive: look at /etc/haproxy/haproxy.cfg on master

2. lets run a terrasort job
<launch terrasort job>

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.
