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

DNSing the heck out of it:

$ docker run -it --rm sequenceiq/alpine-dig dig $FQDN

Where goez my package:

$ docker run -it --rm zburgermeiszter/traceroute $FQDN

CLIs

DC/OS cluster:

$ docker run -it --rm jess/dcos-cli

AWS:

$ docker run -it --rm jess/awscli

Kafka cluster:

$ docker run -it --rm mesosphere/kafka-client

Load testing

$ docker run -it --rm williamyeh/boom -n 1000 -c 100 $URL
