Method 1: Edit Deployment

1. Find the deployment you want to update:

   kubectl get deployments
   

2. Edit the deployment with the updated image:

   kubectl edit deployment <deployment-name>
   

3. In the YAML file, update the image field under the spec.template.spec.containers section with the new image. For example:

   containers:
     - name: my-app
       image: my-app:latest
   

4. Save and exit the YAML file.

Method 2: Rolling Update

1. Set the new image as the desired state for the pods:

   kubectl set image deployment/<deployment-name> <container-name>=<new-image>
   

2. Kubernetes will automatically perform a rolling update, replacing the pods with the new image.

Method 3: Recreate Pods

1. Delete the existing pods:

   kubectl delete pods <pod-name>
   

2. Wait for new pods to be created with the updated image. Kubernetes will automatically recreate the pods according to the updated deployment.

Additional Notes:

• If the updated image requires different resources or configuration, you may need to update the deployment manifest accordingly.
• You can check the status of the update with the command:

  kubectl rollout status deployment/<deployment-name>
