Hi @lenglet-k, I'm digging up this issue to let you know that this is fixed on our end. Can you confirm ? Thank you !

Hi, i have the same behavior in 1.5.7.

[lenglet-k]

@TheophileDiot I have test with 1.5.9.

The first problem is rbac:

We need to add pods/log ressource in bunkerweb clusterrole:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  labels:
    app.kubernetes.io/instance: bunkerweb
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: bunkerweb
    helm.sh/chart: bunkerweb-0-master
  name: bunkerweb
rules:
- apiGroups:
  - ""
  resources:
  - services
  - pods
  - pods/log
  - configmaps
  - secrets
  verbs:
  - get
  - watch
  - list
- apiGroups:
  - networking.k8s.io
  resources:
  - ingresses
  verbs:
  - get
  - watch
  - list

After i have this error:

Ok i have found, this error is due to this code: https://github.com/bunkerity/bunkerweb/blob/v1.5.9/src/ui/main.py#L2058 i had not the KUBERNETES_NAMESPACE environment variable.
I have added like that, in bunkerweb-ui deployment:

        - name: KUBERNETES_NAMESPACE
          valueFrom:
            fieldRef:
              fieldPath: metadata.namespace

Theses update in clusterrole and bunkerwebui deployment need update of helm charts. I have done here: #1340
