Unable to update Minikube Deployment with new image

If you did pull the image outside the minikube cluster and you successfully run it as docker container .. then It should work(check if the IMAGE ID is unique, else if you didnt change anything in dockerfile then newly created image will have the same image ID ) If successfully created , tagged and uploaded like : dockerhub starax/service-frontend-voting:test
You can do these steps

• eval $(minikube docker-env)

• docker images => check the IMAGE IDs and name of images and their tags

• docker pull starax/service-frontend-voting:test => this will download
  the test tag

• run docker images again => to check if image ID , tags are different than the previous onrd

• After that in manifest file kubectl edit deploy service-frontend-voting change imagePullPolicy: IfNotPresent
  and image: starax/service-frontend-voting:test

Notes the command 1. you used wont do anything, because deployment will recreate another pod even if you deleted that pod , the new pod will have the image that is indicated in deployment which is same the old version.kubectl describe service-frontend-voting to check name and tag of the image that being used ..

The command 2,3 will delete, then create a same deployment as before, and the image pulled will be starax/service-frontend-voting:latest

To update image use => 4

About 6, if you don't specify the tag of an image K8s will pulled that image with tag latest tag.Also If you dont indicate imagePullPolicy then policy by default is Always ..

Also check kubectl get events is good command to tell you if you pulled a new image or no

I hope I helped

How to update k8s pod to newer version of image after minikube image load

Managed to solve this myself.
I made a script that would first generate a random number and use it as the image's tag, it would then use kubectl set image to update the image.

$tag = $(Get-Random)
echo "building image"
docker build --build-arg NPM_TOKEN=$(cat .token) -t "sso-service:$tag" .
echo "loading image"
minikube image load "sso-service:$tag" --daemon=true
kubectl set image deployment/sso sso="sso-service:$tag"
