How do you delete all deployments belonging to a specific namespace in Minikube?

To delete all deployments belonging to a specific namespace in Minikube, you can follow these steps:

  1. First, make sure you have Minikube installed and running on your local machine.
  2. Open a terminal and start the Minikube cluster by running the command: minikube start
  3. Switch to the target namespace where your deployments reside using the kubectl command: kubectl config set-context --current --namespace=your-namespace
  4. Verify that you are in the correct namespace by running the following command: kubectl config view --minify | grep namespace:
  5. Now, list all the deployments in the current namespace by executing: kubectl get deployments
  6. To delete all deployments in the namespace, you can use a simple kubectl command that deletes all resources with the kind set to Deployment: kubectl delete deployments --all This command will delete all deployments in the current namespace, including associated ReplicaSets and Pods.
  7. After executing the command, you can verify that the deployments have been deleted by running: kubectl get deployments If no deployments are present, then you have successfully deleted all the deployments belonging to the specified namespace in Minikube.


What happens to the associated pods when you delete a deployment in Minikube?

When you delete a deployment in Minikube, the associated pods created by that deployment are also deleted.


A deployment in Kubernetes is responsible for managing a set of replica pods. When you delete a deployment, Kubernetes initiates the deletion process for all the pods managed by that deployment. It ensures that the specified number of replica pods is maintained during the deletion process to ensure high availability.


Once the deployment is deleted, the associated pods are also terminated. The termination process depends on the termination policy defined for the pods. By default, Kubernetes initiates a graceful termination process, sending a termination signal to the pods, allowing them to gracefully shut down and complete any ongoing tasks. However, if the termination grace period expires or if the pod does not respond to the termination signal, then Kubernetes forcefully terminates the pod.


Therefore, if you delete a deployment in Minikube, all the associated pods managed by that deployment will be destroyed as well.


How to delete a deployment while preserving its configuration in Minikube?

To delete a deployment while preserving its configuration in Minikube, you can follow these steps:

  1. Open a terminal and start Minikube using the command minikube start. This will start the Minikube cluster.
  2. Next, deploy your application using the kubectl command. For example, if your deployment YAML file is named deployment.yaml, you can use the following command to deploy it: kubectl create -f deployment.yaml
  3. Verify that your deployment is running by checking the status: kubectl get deployments
  4. To delete the deployment, use the kubectl delete command followed by the name of your deployment. For example, if your deployment is named my-deployment, the command would be: kubectl delete deployment my-deployment
  5. After deleting the deployment, verify that it has been removed: kubectl get deployments
  6. To preserve the configuration of the deleted deployment, create a backup of the deployment YAML file. Copy the contents or make a backup in a different location.
  7. If you want to redeploy the same deployment later, use the kubectl command to create the deployment again: kubectl create -f deployment.yaml


By following these steps, you can delete a deployment while preserving its configuration in Minikube and then redeploy it using the backup of the deployment YAML file.

How do you delete all deployments in Minikube at once?

To delete all deployments in Minikube at once, you can use the kubectl command-line tool.

  1. Open a terminal or command prompt.
  2. Set the kubectl context to your Minikube cluster by running the following command: kubectl config use-context minikube
  3. Delete all deployments using the following command: kubectl delete deployments --all


This command will delete all deployments in the current namespace, including their associated pods and services. If you have multiple namespaces and want to delete deployments across all namespaces, you can add the --all-namespaces flag to the command:

1
kubectl delete deployments --all --all-namespaces



Can you delete multiple deployments at once in Minikube?

No, Minikube does not provide a built-in option to delete multiple deployments at once. However, you can use shell scripting or automation tools to delete multiple deployments sequentially or in parallel. For example, you can write a shell script that iterates over a list of deployment names and deletes them one by one using kubectl delete deployment <deployment-name>. Alternatively, you can use configuration management or infrastructure-as-code tools like Ansible, Terraform, or Helm to manage and delete Kubernetes deployments.
