To delete a Helm release, you can follow these steps:
- Determine the name of the release you want to delete. You can use the command helm list to see all the releases and their names.
- Run the command helm delete RELEASE_NAME, where RELEASE_NAME is the name of the release you want to delete. This command will send a delete request to Kubernetes, which will remove all the resources associated with the release.
- By default, Helm will mark the release for deletion and remove the resources in the background. You can use the --purge flag to delete the release and its associated resources immediately. For example, helm delete --purge RELEASE_NAME.
- You can verify the deletion of the release by running helm list again. If the release is not listed, it has been successfully deleted.
- If you want to delete all the releases in a namespace, you can use the helm delete --purge --all command. This will delete all releases in the current namespace.
Note: Deleting a release does not automatically delete any persistent volumes associated with it. You might need to delete them manually if required.

What is the step-by-step process to delete a Helm release from a Helm repository?
To delete a Helm release from a Helm repository, you can follow the step-by-step process below:
- Connect to the Kubernetes cluster where Helm is installed using the kubectl command-line tool.
- List all the releases available in the Helm repository by running the following command: helm list
- Identify the release you want to delete from the list. Make a note of the release name.
- Delete the Helm release by using the helm delete command followed by the release name. Specify the --purge flag to completely remove the release and all its associated resources. The command would look like this: helm delete --purge
- Wait for the release to be deleted. You can check the status of the release deletion by running: helm list
- Once the release has been successfully deleted, the release will no longer be listed.
Note that deleting a Helm release will also delete all the Kubernetes resources associated with that release, such as pods, services, deployments, etc.
How to delete a Helm release using a YAML manifest file?
To delete a Helm release using a YAML manifest file, you need to create a YAML file specifying the release’s metadata and other required information.
Here are the steps to delete a Helm release using a YAML manifest file:
- Create a YAML file, for example "delete-release.yaml", and populate it with the following content:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
apiVersion: helm.fluxcd.io/v1 kind: HelmRelease metadata: name: <RELEASE_NAME> namespace: <NAMESPACE_WHERE_RELEASE_IS_INSTALLED> spec: releaseName: <RELEASE_NAME> chart: spec: chart: <CHART_REFERENCE> version: <CHART_VERSION> sourceRef: kind: <SOURCE_KIND> # Kind of the chart source: HelmRepository, GitRepository, or Bucket name: <SOURCE_NAME> # Name of the chart source namespace: <SOURCE_NAMESPACE> # Namespace of the chart source targetNamespace: <NAMESPACE_WHERE_CHART_WAS_INSTALLED> |
Replace <RELEASE_NAME> with the name of the release you want to delete.
Replace <NAMESPACE_WHERE_RELEASE_IS_INSTALLED> with the namespace where the release is installed.
Replace <CHART_REFERENCE> with the reference to the chart you used when installing the release (e.g., "stable/nginx-ingress").
Replace <CHART_VERSION> with the version of the chart you used when installing the release.
Replace <SOURCE_KIND>, <SOURCE_NAME>, and <SOURCE_NAMESPACE> with the details of the chart source, such as HelmRepository, GitRepository, or Bucket.
Replace <NAMESPACE_WHERE_CHART_WAS_INSTALLED> with the namespace where the original chart was installed.
- Save the file.
- Run the following kubectl command to delete the Helm release using the YAML manifest:
1
|
kubectl apply -f delete-release.yaml
|
This will apply the manifest file and initiate the deletion of the Helm release.
Note: Make sure you have the necessary permissions to delete the release in the specified namespace.
How to delete a Helm release using the Helm API?
To delete a Helm release using the Helm API, you can follow these steps:
- Import the required packages:
1 2 |
import requests import json |
- Set the necessary variables:
1 2 |
helm_api_url = "http://localhost:8080/helm/api/v1/releases" # Replace with your Helm API URL release_name = "my-release" # Replace with the name of your release |
- Construct the delete release request:
1 2 3 4 5 6 |
def construct_delete_release_request(release_name): headers = {"Content-Type": "application/json"} data = { "releaseName": release_name } return headers, json.dumps(data) |
- Send the delete release request:
1 2 3 |
def delete_helm_release(api_url, headers, data): response = requests.delete(api_url, headers=headers, data=data) return response.status_code, response.text |
- Call the functions to delete the release:
1 2 3 4 5 |
headers, data = construct_delete_release_request(release_name) status_code, response_text = delete_helm_release(helm_api_url, headers, data) print("Status code:", status_code) print("Response:", response_text) |
Make sure to replace the helm_api_url variable with the correct URL for your Helm API, and the release_name variable with the name of the release you want to delete.
