In our previous post How to configure Grafana on docker, we saw how we can run grafana docker container with SSL and oauth okta.
In this post, we will see how we can run this docker image on kubernetes cluster.
Note: I’m not going to detail out Kubernetes. I will just focus on Dockerfile and the environment variables for that.
I’m assumming you have configured Ingress rule, and exposed Kubernetes service for this grafana dashboard. And, the ingress rule should have the mapping from your cluster IP to app name: trainings
We are going to configure name of our app to trainings
Configuring service
apiVersion: v1
kind: Service
metadata:
name: trainings
spec:
type: ClusterIP
ports:
- port: 80
targetPort: 8080
selector:
app: trainings
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: trainings
annotations:
kubernetes.io/ingress.class: traefik
spec:
rules:
- host: "<your host name>"
http:
paths:
- backend:
serviceName: trainings
servicePort: 80
tls:
- hosts:
- <your hostname>
secretName: trainings-secret
Note: you also have to configure SSL certificate to your cluster.

RUN mkdir -p /var/lib/grafana/dashboards
ADD grafana_dashboards/belts-dashboard.json /var/lib/grafana/dashboards/belts-dashboard.json
ADD grafana_dashboards/dashboards.yaml /etc/grafana/provisioning/dashboards/dashboards.yaml
ADD grafana_dashboards/elastic_datasource.yaml /etc/grafana/provisioning/datasources/elastic_datasource.yaml
EXPOSE 8080
Lets take a look at the Kubernetes configmap yaml file:
apiVersion: v1
kind: ConfigMap
metadata:
name: trainings
data:
GF_SERVER_PROTOCOL: "http"
GF_SERVER_ROOT_URL: "https://<your host name>"
GF_AUTH_GENERIC_OAUTH_CLIENT_ID: "<client id>"
GF_AUTH_GENERIC_OAUTH_CLIENT_SECRET: "<secret>"
GF_SERVER_HTTP_PORT: "8080"
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: trainings
spec:
replicas: 1
template:
metadata:
labels:
app: trainings
spec:
containers:
- name: trainings
image: <your artificatory path to grafana image>:<version>
resources:
limits:
cpu: 1
memory: 1024Mi
requests:
cpu: 1
memory: 1024Mi
envFrom:
- configMapRef:
name: trainings
imagePullSecrets:
- name: <your secret name>
Apply config file
kubectl apply -f config/config.yml
Apply deployment file
kubectl apply -f deployments/deployment.yml
Hit your hostname, and it should redirect you to okta and then to your grafana dashboard.
