# 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.

```console

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.

See: [ducaale/xh](https://github.com/ducaale/xh)

## Example

```yaml

apiVersion: batch/v1beta1

kind: CronJob

metadata:

  creationTimestamp: null

  name: my-cronjob

spec:

  jobTemplate:

    metadata:

      creationTimestamp: null

      name: my-cronjob

    spec:

      template:

        metadata:

          creationTimestamp: null

        spec:

          volumes:

            - name: shared

              emptyDir: {}

          initContainers:

            - name: init-shared

              image: docker.io/upciti/quitquitquit:latest

              command: ["cp", "-r", "/shared/", "/volume/"]

              volumeMounts:

                - name: shared

                  mountPath: "/volume"

          containers:

            - image: image_without_curl:latest

              name: job

              command:

                - /volume/shared/entrypoint.sh

              args:

                - "ls -la /"

              volumeMounts:

                - name: shared

                  mountPath: "/volume"

          restartPolicy: OnFailure
