A very simple, silly little kubectl plugin / utility that guesses which language an application running in a kubernetes pod was written in. Just a PoC after learning Go to prove myself I can write something that's "useful". :)
Note that kubectl-get-pod-app-language is expected to be installed as a kubectl plugin - see installation instructions here.
For standalone usage, first run go build -o app.
Then, choose any of the available commands to run your application with:
Guesses the language. An interactive prompt will guide you towards available pods and containers.
The actual guessing is done by looking at each command in docker history <image> and matching it against a set of available
language heuristics, stored in heuristics.json.
Lists all possible heuristics (derived from heuristics.json) that might indicate the language
an application was written in. Used by get-pod-app-language to make educated guesses.
An easy way to add a new heuristic - just run get-pod-app-language add-to-heuristic java ./gradlew to add the heuristic to heuristic.json.
- Add support for remote docker registries, including secret mgmt.
- Add proper CLI support using Cobra, there's a mish-mash of argument and variable passing in the code that doesn't make a lot of sense
- Support more heuristics -
execing into the container and listing files, looking at actual dockerfile if available, etc..
