This is documentation for the next version of Grafana. For the latest stable release, go to the latest version.
Deploy Grafana on Kubernetes
You can use Grafana Cloud to avoid installing, maintaining, and scaling your own instance of Grafana. Create a free account to get started, which includes free forever access to 10k metrics, 50GB logs, 50GB traces, 500VUh k6 testing & more.
On this page, you will find instructions for installing and running Grafana on Kubernetes using Kubernetes manifests for the setup. If Helm is your preferred option, refer to Grafana Helm community charts.
Watch this video to learn more about installing Grafana on Kubernetes:
Before you begin
To follow this guide:
You need the latest version of Kubernetes running either locally or remotely on a public or private cloud.
If you plan to use it in a local environment, you can use various Kubernetes options such as minikube, kind, Docker Desktop, and others.
If you plan to use Kubernetes in a production setting, it’s recommended to utilize managed cloud services like Google Kubernetes Engine (GKE), Amazon Elastic Kubernetes Service (EKS), or Azure Kubernetes Service (AKS).
System requirements
This section provides minimum hardware and software requirements.
Minimum Hardware Requirements
- Disk space: 1 GB
- Memory: 750 MiB (approx 750 MB)
- CPU: 250m (approx 0.25 cores)
Supported databases
For a list of supported databases, refer to supported databases.
Supported web browsers
For a list of support web browsers, refer to supported web browsers.
Note
Enable port3000
in your network environment, as this is the Grafana default port.
Deploy Grafana OSS on Kubernetes
This section explains how to install Grafana OSS using Kubernetes.
Note
If you want to install Grafana Enterprise on Kubernetes, refer to Deploy Grafana Enterprise on Kubernetes.
If you deploy an application in Kubernetes, it will use the default namespace which may already have other applications running. This can result in conflicts and other issues.
It is recommended to create a new namespace in Kubernetes to better manage, organize, allocate, and manage cluster resources. For more information about Namespaces, refer to the official Kubernetes documentation.
To create a namespace, run the following command:
kubectl create namespace my-grafana
In this example, the namespace is
my-grafana
To verify and view the newly created namespace, run the following command:
kubectl get namespace my-grafana
The output of the command provides more information about the newly created namespace.
Create a YAML manifest file named
grafana.yaml
. This file will contain the necessary code for deployment.touch grafana.yaml
In the next step you define the following three objects in the YAML file.
Object Description Persistent Volume Claim (PVC) This object stores the data. Service This object provides network access to the Pod defined in the deployment. Deployment This object is responsible for creating the pods, ensuring they stay up to date, and managing Replicaset and Rolling updates. Copy and paste the following contents and save it in the
grafana.yaml
file.--- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: grafana-pvc spec: accessModes: - ReadWriteOnce resources: requests: storage: 1Gi --- apiVersion: apps/v1 kind: Deployment metadata: labels: app: grafana name: grafana spec: selector: matchLabels: app: grafana template: metadata: labels: app: grafana spec: securityContext: fsGroup: 472 supplementalGroups: - 0 containers: - name: grafana image: grafana/grafana:latest imagePullPolicy: IfNotPresent ports: - containerPort: 3000 name: http-grafana protocol: TCP readinessProbe: failureThreshold: 3 httpGet: path: /robots.txt port: 3000 scheme: HTTP initialDelaySeconds: 10 periodSeconds: 30 successThreshold: 1 timeoutSeconds: 2 livenessProbe: failureThreshold: 3 initialDelaySeconds: 30 periodSeconds: 10 successThreshold: 1 tcpSocket: port: 3000 timeoutSeconds: 1 resources: requests: cpu: 250m memory: 750Mi volumeMounts: - mountPath: /var/lib/grafana name: grafana-pv volumes: - name: grafana-pv persistentVolumeClaim: claimName: grafana-pvc --- apiVersion: v1 kind: Service metadata: name: grafana spec: ports: - port: 3000 protocol: TCP targetPort: http-grafana selector: app: grafana sessionAffinity: None type: LoadBalancer
Run the following command to send the manifest to the Kubernetes API server:
kubectl apply -f grafana.yaml --namespace=my-grafana
This command creates the PVC, Deployment, and Service objects.
Complete the following steps to verify the deployment status of each object.
a. For PVC, run the following command:
kubectl get pvc --namespace=my-grafana -o wide
b. For Deployment, run the following command:
kubectl get deployments --namespace=my-grafana -o wide
c. For Service, run the following command:
kubectl get svc --namespace=my-grafana -o wide
Access Grafana on Managed K8s Providers
In this task, you access Grafana deployed on a Managed Kubernetes provider using a web browser. Accessing Grafana via a web browser is straightforward if it is deployed on a Managed Kubernetes Provider as it uses the cloud provider’s LoadBalancer to which the external load balancer routes are automatically created.
Run the following command to obtain the deployment information:
kubectl get all --namespace=my-grafana
The output returned should look similar to the following:
NAME READY STATUS RESTARTS AGE pod/grafana-69946c9bd6-kwjb6 1/1 Running 0 7m27s NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/grafana LoadBalancer 10.5.243.226 1.120.130.330 3000:31171/TCP 7m27s NAME READY UP-TO-DATE AVAILABLE AGE deployment.apps/grafana 1/1 1 1 7m29s NAME DESIRED CURRENT READY AGE replicaset.apps/grafana-69946c9bd6 1 1 1 7m30s
Identify the EXTERNAL-IP value in the output and type it into your browser.
The Grafana sign-in page appears.
To sign in, enter
admin
for both the username and password.If you do not see the EXTERNAL-IP, complete the following steps:
a. Run the following command to do a port-forwarding of the Grafana service on port
3000
.kubectl port-forward service/grafana 3000:3000 --namespace=my-grafana
For more information about port-forwarding, refer to Use Port Forwarding to Access Applications in a Cluster.
b. Navigate to
localhost:3000
in your browser.The Grafana sign-in page appears.
c. To sign in, enter
admin
for both the username and password.
Access Grafana using minikube
There are multiple ways to access the Grafana UI on a web browser when using minikube. For more information about minikube, refer to How to access applications running within minikube.
This section lists the two most common options for accessing an application running in minikube.
Option 1: Expose the service
This option uses the type: LoadBalancer
in the grafana.yaml
service manifest, which makes the service accessible through the minikube service
command. For more information, refer to minikube Service command usage.
Run the following command to obtain the Grafana service IP:
minikube service grafana --namespace=my-grafana
The output returns the Kubernetes URL for service in your local cluster.
|------------|---------|-------------|------------------------------| | NAMESPACE | NAME | TARGET PORT | URL | |------------|---------|-------------|------------------------------| | my-grafana | grafana | 3000 | http://192.168.122.144:32182 | |------------|---------|-------------|------------------------------| Opening service my-grafana/grafana in default browser... http://192.168.122.144:32182
Run a
curl
command to verify whether a given connection should work in a browser under ideal circumstances.curl 192.168.122.144:32182
The following example output shows that an endpoint has been located:
<a href="/login">Found</a>.
Access the Grafana UI in the browser using the provided IP:Port from the command above. For example
192.168.122.144:32182
The Grafana sign-in page appears.
To sign in to Grafana, enter
admin
for both the username and password.
Option 2: Use port forwarding
If Option 1 does not work in your minikube environment (this mostly depends on the network), then as an alternative you can use the port forwarding option for the Grafana service on port 3000
.
For more information about port forwarding, refer to Use Port Forwarding to Access Applications in a Cluster.
To find the minikube IP address, run the following command:
minikube ip
The output contains the IP address that you use to access the Grafana Pod during port forwarding.
A Pod is the smallest deployment unit in Kubernetes and is the core building block for running applications in a Kubernetes cluster. For more information about Pods, refer to Pods.
To obtain the Grafana Pod information, run the following command:
kubectl get pods --namespace=my-grafana
The output should look similar to the following:
NAME READY STATUS RESTARTS AGE grafana-58445b6986-dxrrw 1/1 Running 0 9m54s
The output shows the Grafana POD name in the
NAME
column, that you use for port forwarding.Run the following command for enabling the port forwarding on the POD:
kubectl port-forward pod/grafana-58445b6986-dxrrw --namespace=my-grafana --address 0.0.0.0 3000:3000
To access the Grafana UI on the web browser, type the minikube IP along with the forwarded port. For example
192.168.122.144:3000
The Grafana sign-in page appears.
To sign in to Grafana, enter
admin
for both the username and password.
Update an existing deployment using a rolling update strategy
Rolling updates enable deployment updates to take place with no downtime by incrementally updating Pods instances with new ones. The new Pods will be scheduled on nodes with available resources. For more information about rolling updates, refer to Performing a Rolling Update.
The following steps use the kubectl annotate
command to add the metadata and keep track of the deployment. For more information about kubectl annotate
, refer to kubectl annotate documentation.
Note
Instead of using theannotate
flag, you can still use the--record
flag. However, it has been deprecated and will be removed in the future version of Kubernetes. See: https://github.com/kubernetes/kubernetes/issues/40422
To view the current status of the rollout, run the following command:
kubectl rollout history deployment/grafana --namespace=my-grafana
The output will look similar to this:
deployment.apps/grafana REVISION CHANGE-CAUSE 1 NONE
The output shows that nothing has been updated or changed after applying the
grafana.yaml
file.To add metadata to keep record of the initial deployment, run the following command:
kubectl annotate deployment/grafana kubernetes.io/change-cause='deployed the default base yaml file' --namespace=my-grafana
To review the rollout history and verify the changes, run the following command:
kubectl rollout history deployment/grafana --namespace=my-grafana
You should see the updated information that you added in the
CHANGE-CAUSE
earlier.
Change Grafana image version
To change the deployed Grafana version, run the following
kubectl edit
command:kubectl edit deployment grafana --namespace=my-grafana
In the editor, change the container image under the
kind: Deployment
section.For example:
From
yaml image: grafana/grafana-oss:10.0.1
To
yaml image: grafana/grafana-oss-dev:10.1.0-124419pre
Save the changes.
Once you save the file, you receive a message similar to the following:
deployment.apps/grafana edited
This means that the changes have been applied.
To verify that the rollout on the cluster is successful, run the following command:
kubectl rollout status deployment grafana --namespace=my-grafana
A successful deployment rollout means that the Grafana Dev cluster is now available.
To check the statuses of all deployed objects, run the following command and include the
-o wide
flag to get more detailed output:kubectl get all --namespace=my-grafana -o wide
You should see the newly deployed
grafana-oss-dev
image.To verify it, access the Grafana UI in the browser using the provided IP:Port from the command above.
The Grafana sign-in page appears.
To sign in to Grafana, enter
admin
for both the username and password.In the top-right corner, click the help icon.
The version information appears.
Add the
change cause
metadata to keep track of things using the commands:kubectl annotate deployment grafana --namespace=my-grafana kubernetes.io/change-cause='using grafana-oss-dev:10.1.0-124419pre for testing'
To verify, run the
kubectl rollout history
command:kubectl rollout history deployment grafana --namespace=my-grafana
You will see an output similar to this:
deployment.apps/grafana REVISION CHANGE-CAUSE 1 deploying the default yaml 2 using grafana-oss-dev:10.1.0-124419pre for testing
This means that REVISION#2
is the current version.
Note
The last line of thekubectl rollout history deployment
command output is the one which is currently active and running on your Kubernetes environment.
Roll back a deployment
When the Grafana deployment becomes unstable due to crash looping, bugs, and so on, you can roll back a deployment to an earlier version (a REVISION
).
By default, Kubernetes deployment rollout history remains in the system so that you can roll back at any time. For more information, refer to Rolling Back to a Previous Revision.
To list all possible
REVISION
values, run the following command:kubectl rollout history deployment grafana --namespace=my-grafana
To roll back to a previous version, run the
kubectl rollout undo
command and provide a revision number.Example: To roll back to a previous version, specify the
REVISION
number, which appears after you run thekubectl rollout history deployment
command, in the--to-revision
parameter.kubectl rollout undo deployment grafana --to-revision=1 --namespace=my-grafana
To verify that the rollback on the cluster is successful, run the following command:
kubectl rollout status deployment grafana --namespace=my-grafana
Access the Grafana UI in the browser using the provided IP:Port from the command above.
The Grafana sign-in page appears.
To sign in to Grafana, enter
admin
for both the username and password.In the top-right corner, click the help icon to display the version number.
To see the new rollout history, run the following command:
kubectl rollout history deployment grafana --namespace=my-grafana
If you need to go back to any other REVISION
, just repeat the steps above and use the correct revision number in the --to-revision
parameter.
Provision Grafana resources using configuration files
Provisioning can add, update, or delete resources specified in your configuration files when Grafana starts. For detailed information, refer to Grafana Provisioning.
This section outlines general instructions for provisioning Grafana resources within Kubernetes, using a persistent volume to supply the configuration files to the Grafana pod.
Add a new
PersistentVolumeClaim
to thegrafana.yaml
file.--- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: grafana-provisioning-pvc spec: accessModes: - ReadWriteOnce resources: requests: storage: 1Mi
In the
grafana.yaml
file, mount the persistent volume into/etc/grafana/provisioning
as follows.... volumeMounts: - mountPath: /etc/grafana/provisioning name: grafana-provisioning-pv ... volumes: - name: grafana-provisioning-pv persistentVolumeClaim: claimName: grafana-provisioning-pvc ...
Find or create the provision resources you want to add. For instance, create a
alerting.yaml
file adding a mute timing (alerting resource).apiVersion: 1 muteTimes: - orgId: 1 name: MuteWeekends time_intervals: - weekdays: [saturday, sunday]
By default, configuration files for alerting resources need to be placed in the
provisioning/alerting
directory.Save the
alerting.yaml
file in a directory namedalerting
, as we will next supply thisalerting
directory to the/etc/grafana/provisioning
folder of the Grafana pod.Verify first the content of the provisioning directory in the running Grafana pod.
kubectl exec -n my-grafana <pod_name> -- ls /etc/grafana/provisioning/
kubectl exec -n my-grafana <pod_name> -- ls /etc/grafana/provisioning/alerting
Because the
alerting
folder is not available yet, the last command should output aNo such file or directory
error.Copy the local
alerting
directory to/etc/grafana/provisioning/
in the Grafana pod.kubectl cp alerting my-grafana/<pod_name>:/etc/grafana/provisioning/
You can follow the same process to provision additional Grafana resources by supplying the following folders:
provisioning/dashboards
provisioning/datasources
provisioning/plugins
Verify the
alerting
directory in the running Grafana pod includes thealerting.yaml
file.kubectl exec -n my-grafana <pod_name> -- ls /etc/grafana/provisioning/alerting
Restart the Grafana pod to provision the resources.
kubectl rollout restart -n my-grafana deployment --selector=app=grafana
Note that
rollout restart
kills the previous pod and scales a new pod. When the old pod terminates, you may have to enable port-forwarding in the new pod. For instructions, refer to the previous sections about port forwarding in this guide.Verify the Grafana resources are properly provisioned within the Grafana instance.
Troubleshooting
This section includes troubleshooting tips you might find helpful when deploying Grafana on Kubernetes.
Collecting logs
It is important to view the Grafana server logs while troubleshooting any issues.
To check the Grafana logs, run the following command:
# dump Pod logs for a Deployment (single-container case) kubectl logs --namespace=my-grafana deploy/grafana
If you have multiple containers running in the deployment, run the following command to obtain the logs only for the Grafana deployment:
# dump Pod logs for a Deployment (multi-container case) kubectl logs --namespace=my-grafana deploy/grafana -c grafana
For more information about accessing Kubernetes application logs, refer to Pods and Deployments.
Increasing log levels to debug mode
By default, the Grafana log level is set to info
, but you can increase it to debug
mode to fetch information needed to diagnose and troubleshoot a problem. For more information about Grafana log levels, refer to Configuring logs.
The following example uses the Kubernetes ConfigMap which is an API object that stores non-confidential data in key-value pairs. For more information, refer to Kubernetes ConfigMap Concept.
Create a empty file and name it
grafana.ini
and add the following:[log] ; # Either "debug", "info", "warn", "error", "critical", default is "info" ; # we change from info to debug level level = debug
This example adds the portion of the log section from the configuration file. You can refer to the Configure Grafana documentation to view all the default configuration settings.
To add the configuration file into the Kubernetes cluster via the ConfigMap object, run the following command:
kubectl create configmap ge-config --from-file=/path/to/file/grafana.ini --namespace=my-grafana
To verify the ConfigMap object creation, run the following command:
kubectl get configmap --namespace=my-grafana
Open the
grafana.yaml
file and In the Deployment section, provide the mount path to the custom configuration (/etc/grafana
) and reference the newly created ConfigMap for it.--- apiVersion: apps/v1 kind: Deployment metadata: labels: app: grafana name: grafana # the rest of the code remains the same. ... .... ... requests: cpu: 250m memory: 750Mi volumeMounts: - mountPath: /var/lib/grafana name: grafana-pv # This is to mount the volume for the custom configuration - mountPath: /etc/grafana name: ge-config volumes: - name: grafana-pv persistentVolumeClaim: claimName: grafana-pvc # This is to provide the reference to the ConfigMap for the volume - name: ge-config configMap: name: ge-config
Deploy the manifest using the following kubectl apply command:
kubectl apply -f grafana.yaml --namespace=my-grafana
To verify the status, run the following commands:
# first check the rollout status kubectl rollout status deployment grafana --namespace=my-grafana # then check the deployment and configMap information kubectl get all --namespace=my-grafana
To verify it, access the Grafana UI in the browser using the provided IP:Port
The Grafana sign-in page appears.
To sign in to Grafana, enter
admin
for both the username and password.Navigate to Server Admin > Settings and then search for log.
You should see the level to debug mode.
Using the –dry-run command
You can use the Kubernetes --dry-run
command to send requests to modifying endpoints and determine if the request would have succeeded.
Performing a dry run can be useful for catching errors or unintended consequences before they occur. For more information, refer to Kubernetes Dry-run.
Example:
The following example shows how to perform a dry run when you make changes to the grafana.yaml
such as using a new image version, or adding new labels and you want to determine if there are syntax errors or conflicts.
To perform a dry run, run the following command:
kubectl apply -f grafana.yaml --dry-run=server --namespace=grafana
If there are no errors, then the output will look similar to this:
persistentvolumeclaim/grafana-pvc unchanged (server dry run)
deployment.apps/grafana unchanged (server dry run)
service/grafana unchanged (server dry run)
If there are errors or warnings, you will see them in the terminal.
Remove Grafana
If you want to remove any of the Grafana deployment objects, use the kubectl delete command
.
If you want to remove the complete Grafana deployment, run the following command:
kubectl delete -f grafana.yaml --namespace=my-grafana
This command deletes the deployment, persistentvolumeclaim, and service objects.
To delete the ConfigMap, run the following command:
kubectl delete configmap ge-config --namespace=my-grafana
Deploy Grafana Enterprise on Kubernetes
The process for deploying Grafana Enterprise is almost identical to the preceding process, except for additional steps that are required for adding your license file.
Obtain Grafana Enterprise license
To run Grafana Enterprise, you need a valid license.
To obtain a license, contact a Grafana Labs representative.
This topic assumes that you have a valid license in a license.jwt
file.
Associate your license with a URL that you can use later in the topic.
Create license secret
Create a Kubernetes secret from your license file using the following command:
kubectl create secret generic ge-license --from-file=/path/to/your/license.jwt
Create Grafana Enterprise configuration
Create a Grafana configuration file with the name
grafana.ini
Paste the following YAML contents into the file you created:
[enterprise] license_path = /etc/grafana/license/license.jwt [server] root_url =/your/license/root/url
Update the
root_url
field to the url associated with the license provided to you.
Create Configmap for Grafana Enterprise configuration
Create a Kubernetes Configmap from your grafana.ini
file with the following command:
kubectl create configmap ge-config --from-file=/path/to/your/grafana.ini
Create Grafana Enterprise Kubernetes manifest
Create a
grafana.yaml
file, and copy-and-paste the following content into it.The following YAML is identical to the one for a Grafana installation, except for the additional references to the Configmap that contains your Grafana configuration file and the secret that has your license.
--- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: grafana-pvc spec: accessModes: - ReadWriteOnce resources: requests: storage: 1Gi --- apiVersion: apps/v1 kind: Deployment metadata: labels: app: grafana name: grafana spec: selector: matchLabels: app: grafana template: metadata: labels: app: grafana spec: securityContext: fsGroup: 472 supplementalGroups: - 0 containers: - image: grafana/grafana-enterprise:latest imagePullPolicy: IfNotPresent name: grafana ports: - containerPort: 3000 name: http-grafana protocol: TCP readinessProbe: failureThreshold: 3 httpGet: path: /robots.txt port: 3000 scheme: HTTP initialDelaySeconds: 10 periodSeconds: 30 successThreshold: 1 timeoutSeconds: 2 resources: limits: memory: 4Gi requests: cpu: 100m memory: 2Gi volumeMounts: - mountPath: /var/lib/grafana name: grafana-pv - mountPath: /etc/grafana name: ge-config - mountPath: /etc/grafana/license name: ge-license volumes: - name: grafana-pv persistentVolumeClaim: claimName: grafana-pvc - name: ge-config configMap: name: ge-config - name: ge-license secret: secretName: ge-license --- apiVersion: v1 kind: Service metadata: name: grafana spec: ports: - port: 3000 protocol: TCP targetPort: http-grafana selector: app: grafana sessionAffinity: None type: LoadBalancer
Caution
If you useLoadBalancer
in the Service and depending on your cloud platform and network configuration, doing so might expose your Grafana instance to the Internet. To eliminate this risk, useClusterIP
to restrict access from within the cluster Grafana is deployed to.To send the manifest to Kubernetes API Server, run the following command:
kubectl apply -f grafana.yaml
To verify the manifest was sent, run the following command:
kubectl port-forward service/grafana 3000:3000
Navigate to
localhost:3000
in your browser.You should see the Grafana login page.
Use
admin
for both the username and password to login.To verify you are working with an enterprise license, scroll to the bottom of the page where you should see
Enterprise (Licensed)
.
