## Allow argo to create services
In order for monitord to expose **open cloud services** on the node, we need to give him permission to create **k8s services**.
For that we can update the RBAC configuration for a role already created by argo :
### Manually edit the rbac authorization
> kubectl edit roles.rbac.authorization.k8s.io -n argo argo-role
In rules add a new entry :
```
- apiGroups:
- ""
resources:
- services
verbs:
- get
- create
```
### Patch the rbac authorization with a one liner
> kubectl patch role argo-role -n argo --type='json' -p='[{"op": "add", "path": "/rules/-", "value": {"apiGroups": [""], "resources": ["services"], "verbs": ["get","create"]}}]'
### Check wether the modification is effective
> kubectl auth can-i create services --as=system:serviceaccount:argo:argo -n argo
This command **must return "yes"**
## TODO
- [ ] Logs the output of each pods :
- logsPods() function already exists
- need to implement the logic to create each pod's logger and start the monitoring routing
- [ ] Allow the front to known on which IP the service are reachable
- currently doing it by using `kubectl get nodes -o wide`
