Helm upgrade with same chart version, but different Docker image tag

I have a question about a Helm upgrade. I'm working on a chart foo-1.0.0 which deploys a pod with a docker image bar:4.5.1.

I have a release "myrelease" based on this chart foo in version 1.0.0 (with a bar:4.5.1 running inside).

Now, I make a fix on bar, rebuild the image bar:4.5.2, change the image in the chart but I did not bump its version. It is still foo-1.0.0

I launch:

$ helm upgrade myrelease repo/foo --version 1.0.0

My problem is that after the upgrade, my pod is still running the bar:4.5.1 instead the 4.5.2

Is the a "cache" in tiller? It seems that tiller did not download foo-1.0.0 again. Is there a way to force it to download?

You need to change the tag version in the image section of values.yaml:

image:
  repository: bar
  tag: 4.5.2
  pullPolicy: Always

and then run the following command:

helm upgrade myrelease repo/foo

or just run the following:

helm upgrade myrelease repo/foo --set=image.tag=1.2.2

and set the applicable image version.
