quitquitquit

Docker image to ease the use of K8S jobs within an istio mesh.

This image is intended to be placed in initContainer of a pod in a job/cronjob.

Why?

Currently, istio is a bit complicated to use in strict mode for jobs and cronjobs.

The job remains in NotReady even after the job is executed.

NAME                             READY   STATUS      RESTARTS   AGE
demo-4cbb2                       1/2     NotReady    0          12s

The solution is to make a POST request to proxy-agent.

This small image allows the use of istio in jobs using containers without curl or wget.

xh

xh is a alternative to curl written in rust and does not require any dependencies.
