Kubernetes bash scheduler
This is a really bad idea
I made it because it was helpful for me to learn 
I hope you learn something too.
How to run it
Please don't ever use this on a production kubernetes cluster!!!
Run it against a local kind cluster.
kind create cluster
Create pods that use the custom scheduler.
kubectl apply -f https://raw.githubusercontent.com/rothgar/bashScheduler/main/nginx.deploy.yaml
You should see nginx pods with Pending status
NAME READY STATUS RESTARTS AGE
nginx-56dcc974bc-8ss4m 0/1 Pending 0 49m
nginx-56dcc974bc-94ltw 0/1 Pending 0 49m
nginx-56dcc974bc-tnz6s 0/1 Pending 0 49m
Then proxy your localhost to the kubernetes api server
kubectl proxy
Starting to serve on 127.0.0.1:8001
Now in a new terminal run
curl -sL https://raw.githubusercontent.com/rothgar/bashScheduler/main/scheduler.sh | bash
You should see similar output to
Assigned nginx-56dcc974bc-8ss4m to kind-control-plane
Assigned nginx-56dcc974bc-94ltw to kind-control-plane
Assigned nginx-56dcc974bc-tnz6s to kind-control-plane
Look at the code and see what it's doing.
Uncomment set -x to see all the commands run.
Have fun
