proxy-kube
a local kube-proxy emulator which uses pykube and haproxy to create localhost addresses and /etc/hosts entries for pods in a kubernetes cluster.
IMPORTANT: you must be able to route to the pods for this to be useful!
Caveats
proxy-kube currently only supports a single namespace per context. Since it's only set up to serve short name (vs FQDN) names in /etc/hosts the dependency chain would be too difficult to manage
Usage
You can get help with the -h flag:
usage: proxy-kube.py [-h] [-c CONTEXT] [-e EXCLUDE] [-n NAMESPACE]
optional arguments:
-h, --help show this help message and exit
-c CONTEXT, --context CONTEXT
specify context
-e EXCLUDE, --exclude EXCLUDE
specify exclude
-n NAMESPACE, --namespace NAMESPACE
specify namespace```
For the simplest case you only need to provide a context via command-line
```$ ./proxy-kube.py -c minikube
Using CLI overrides, trying to build out config...
context: minikube
Setting namespace to default...
