fix imagePullPolicy #306

Open simonfelding opened 3 months ago

simonfelding commented 3 months ago

If imagePullPolicy is set to IfNotPresent and the tag is :latest, you get very unintuitive behavior where Kubernetes will not actually get new versions. This kind of behavior is exactly why it's bad practice to use that tag.

It would probably be better to drop the explicit definition of the image pull policy and let the Kubernetes mutation webhook do its magic for the image tags.
