Steps to Reproduce:
kubernetes/manifest/base/webui-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
name: open-webui-deployment
namespace: open-webui
spec:
replicas: 1
selector:
matchLabels:
app: open-webui
template:
metadata:
labels:
app: open-webui
spec:
containers:
- name: open-webui
image: ghcr.io/open-webui/open-webui:main
ports:
- containerPort: 8080
resources:
requests:
cpu: "500m"
memory: "500Mi"
limits:
cpu: "1000m"
memory: "1Gi"
env:
- name: OLLAMA_BASE_URL
value: "http://ollama-service.open-webui.svc.cluster.local:11434"
tty: true
volumeMounts:
- name: webui-volume
mountPath: /app/backend/data
volumes:
- name: webui-volume
persistentVolumeClaim:
claimName: open-webui-pvc

Expected Behavior:

Note

solutions:

kubernetes/manifest/base/webui-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
name: open-webui-deployment
namespace: open-webui
spec:
replicas: 1
selector:
matchLabels:
app: open-webui
template:
metadata:
labels:
app: open-webui
spec:
containers:
- name: open-webui
image: ghcr.io/open-webui/open-webui:main
ports:
- containerPort: 8080
resources:
requests:
cpu: "500m"
memory: "500Mi"
limits:
cpu: "1000m"
memory: "1Gi"
env:
- name: OLLAMA_BASE_URL
value: "http://ollama-service.open-webui.svc.cluster.local:11434/api"
tty: true
volumeMounts:
- name: webui-volume
mountPath: /app/backend/data
volumes:
- name: webui-volume
persistentVolumeClaim:
claimName: open-webui-pvc

in the yaml file, the ollama_base_url is not correct, it works if I change "env:
- name: OLLAMA_BASE_URL
value: "http://ollama-service.open-webui.svc.cluster.local:11434/"" to "env:
- name: OLLAMA_BASE_URL
value: "http://ollama-service.open-webui.svc.cluster.local:11434/api".
