![GitHub commit activity](https://img.shields.io/github/commit-activity/m/sukeesh/k8s-job-notify?color=red&logo=github&style=flat-square)This tool sends an alert to slack whenever there is a [Kubernetes](https://github.com/kubernetes/kubernetes) cronJob/Job failure/success.
**No extra setup** required to deploy this tool on to your cluster, just apply below K8s deploy manifest 🎉
This uses `InClusterConfig` for accessing Kubernetes API.
## Limitations
- Namespace scoped i.e., each namespace should have this deploy _separately_
- **All the jobs** in the namespace are fetched and verified for failures
- Will add support for selectors in future 📋## Development
If you wish to run this locally, clone this repository, set `webhook` and `namespace` env variables.
This expects kube config to be in `~/.kube/config` (default)```sh
$ export webhook="slack_webhook_url" && export namespace="" && go build && ./k8s-job-notify
```You can also adjust the notification level to `failed` instead of `all` so that it only sends failed notificatinos.
```sh
$ export webhook="slack_webhook_url" && export namespace="" && export notification_level="failed" && go build && ./k8s-job-notify
```Docker 🐳

- If you wish to use unstable, use `image: sukeesh/k8s-job-notify:beta` (triggered whenever push to `master` is made)## To start using this
Create and apply below kubernetes deployment in your cluster
```yaml
apiVersion: apps/v1
