# Deploy OpenMetadata on Kubernetes
|
|
|
|
[](https://artifacthub.io/packages/search?repo=open-metadata)
|
|
|
|
## Introduction
|
|
|
|
[openmetadata-helm-charts](https://github.com/open-metadata/openmetadata-helm-charts) houses Kubernetes [Helm](https://helm.sh) charts for deploying OpenMetadata and its dependencies (Elasticsearch and MySQL) on a Kubernetes cluster.
|
|
|
|
## Prerequisites
|
|
|
|
* A [Kubernetes cluster](https://kubernetes.io) on any cloud
|
|
* [kubectl](https://kubernetes.io/docs/tasks/tools/) to manage Kubernetes resources
|
|
* [Helm](https://helm.sh) to deploy resources based on Helm charts from the OpenMetadata repository
|
|

|
Note, OpenMetadata only supports Helm 3

|
|
|
|
## Quickstart
|
|
|
|
Assuming Kubernetes setup is done and your Kubernetes context points to a correct Kubernetes cluster, first we create kubernetes secrets that contains MySQL and Airflow passwords as secrets.
|
|
|
|
```
|
|
kubectl create secret generic mysql-secrets --from-literal=openmetadata-mysql-password=openmetadata_password
|
|
kubectl create secret generic airflow-secrets --from-literal=openmetadata-airflow-password=admin
|
|
```
|
|
|
|
The above commands sets the passwords as an example. Change to any password of choice.
|
|
|
|
Next, we install OpenMetadata dependencies.
|
|
|
|
Add the OpenMetadata Helm repository by running the following command.
|
|
|
|
```
|
|
helm repo add open-metadata https://helm.open-metadata.org/
|
|
```
|
|
|
|
Run the command `helm repo list` to ensure the OpenMetadata repository was added.
|
|
|
|
```
|
|
NAME URL
|
|
open-metadata https://helm.open-metadata.org/
|
|
```
|
|
|
|
Deploy the dependencies by running the following command.
|
|
|
|
```
|
|
helm install openmetadata-dependencies open-metadata/openmetadata-dependencies
|
|
```
|
|
|
|
{% hint style="info" %}
|
|
Note - The above command uses configurations defined [here](https://raw.githubusercontent.com/open-metadata/openmetadata-helm-charts/main/charts/deps/values.yaml). You can modify any configuration and deploy by passing your own `values.yaml`
|
|
|
|
```
|
|
helm install openmetadata-dependencies open-metadata/openmetadata-dependencies --values <<path-to-values-file>>
|
|
```
|
|
{% endhint %}
|
|
|
|
Run `kubectl get pods` to check whether all the pods for the dependencies are running. You should get a result similar to below.
|
|
|
|
```
|
|
NAME READY STATUS RESTARTS AGE
|
|
elasticsearch-0 1/1 Running 0 3m56s
|
|
mysql-0 1/1 Running 0 3m56s
|
|
```
|
|
|
|
Next, deploy OpenMetadata by running the following command.
|
|
|
|
```
|
|
helm install openmetadata open-metadata/openmetadata
|
|
```
|
|
|
|
Values in [values.yaml](https://raw.githubusercontent.com/open-metadata/openmetadata-helm-charts/main/charts/openmetadata/values.yaml) are preset to match with dependencies deployed using [openmetadata-dependencies](https://github.com/open-metadata/openmetadata-helm-charts/tree/main/charts/deps) with release name "openmetadata-dependencies". If you deployed helm chart using different release name, make sure to update values.yaml accordingly before installing.
|
|
|
|
Run `kubectl get pods` to check the status of pods running. You should get a result similar to the output below.
|
|
|
|
```
|
|
NAME READY STATUS RESTARTS AGE
|
|
elasticsearch-0 1/1 Running 0 5m34s
|
|
mysql-0 1/1 Running 0 5m34s
|
|
openmetadata-5566f4d8b9-544gb 1/1 Running 0 98s
|
|
```
|
|
|
|
{% hint style="info" %}
|
|
To expose the OpenMetadata UI on a local Kubernetes instance, run this command.
|
|
|
|
```
|
|
kubectl port-forward <openmetadata-front end pod name> 8585:8585
|
|
```
|
|
{% endhint %}
|
|
|
|
## Troubleshooting
|
|
|
|
### View helm chart deployment status
|
|
|
|
Run the below command to view status of openmetadata helm chart deployed -
|
|
|
|
```
|
|
helm status openmetadata
|
|
```
|
|
|
|
For more information, visit helm command line reference [here](https://helm.sh/docs/helm/helm\_status/).
|
|
|
|
### View openmetadata kubernetes pod logs
|
|
|
|
Run the below command to list openmetadata kubernetes pods deployed in a namespace -
|
|
|
|
```
|
|
kubectl get pods --namespace <NAMESPACE_NAME> -l='app.kubernetes.io/managed-by=Helm,app.kubernetes.io/instance=<RELEASE_NAME>'
|
|
```
|
|
|
|
Example, list pods deployed by helm release name 'ometa' in the namespace 'ometa-dev' -
|
|
|
|
```
|
|
kubectl get pods --namespace ometa-dev -l='app.kubernetes.io/managed-by=Helm,app.kubernetes.io/instance=ometa'
|
|
```
|
|
|
|
Next, view the logs of pod by running the below command,
|
|
|
|
```
|
|
kubectl logs <POD_NAME> --namespace <NAMESPACE_NAME>
|
|
```
|
|
|
|
For more information, visit the kubectl logs command line reference documentation [here](https://kubernetes.io/docs/tasks/debug-application-cluster/debug-running-pod/).
