To add secrets to a Helm chart, you can follow these steps:
- Create Kubernetes Secrets:
First, create the Kubernetes secrets that you want to include in your Helm chart. You can do this using kubectl or by defining them in YAML files. For example, to create a secret containing a database password, you can run:
- Modify the Helm Chart:
Here, my-secret-key is a placeholder for the secret key, and my-secret is the name of the Kubernetes secret you created.
- Access Secrets in Templates:
In your Helm chart templates, you can reference the secrets using the placeholders you defined in the values.yaml file. For example, if you want to use the secret in a Deployment manifest:
In this example, {{ .Values.secrets.my-secret-key }} references the name of the Kubernetes secret you defined in your values.yaml file.
- Install or Upgrade the Helm Chart:
When you install or upgrade the Helm chart, provide the actual secret values as part of the Helm command using the --set flag. For example:
Replace my-release with the desired release name and ./my-chart with the path to your Helm chart.
By following these steps, you can add and use Kubernetes secrets within your Helm charts. This approach allows you to keep sensitive information separate from your chart and provides flexibility in managing secret values during installation or upgrade.
