How do we update the imagePullPolicy
alone for certain deployments using kubectl
? The image tag has changed, however we don't require a restart. Need to update existing deployments with --image-pull-policy
as IfNotPresent
Note: Don't have the complete YAML or JSON for the deployments, hence need to do it via kubectl

If you need to do this across several deployments, here is a code to help
from kubernetes import client, config
# Load the Kubernetes configuration from default location
config.load_kube_config()
# Create a Kubernetes API client
api = client.AppsV1Api()
# Set the namespace to update deployments in
namespace = "my-namespace"
# Get a list of all deployments in the namespace
deployments = api.list_namespaced_deployment(namespace)
# Loop through each deployment and update its imagePullPolicy
for deployment in deployments.items:
deployment.spec.template.spec.image_pull_policy = "Always"
api.patch_namespaced_deployment(
name=deployment.metadata.name,
namespace=namespace,
body=deployment
)

use
kubectl edit deployment <deployment_name> -n namespace
Then you will be able to edit imagePullPolicy
