job names produce kube api warning

Job names contain the assigned IP address, which contains dots.

```
{"level":"info","ts":"2026-01-27T18:45:11.024Z","logger":"KubeAPIWarningLogger","msg":"metadata.name: this is used in Pod names and hostnames, which can result in surprisi
ng behavior; a DNS label is recommended: [must not contain dots]"}
```

Maybe dashes can be used instead of dots.
