ambassador helm chart deprecation warnings

[RafalSkolasinski]

Since around last week ambassador installation renders following warning.

DEPRECATED!! This version of the chart has been deprecated.

We should verify if this requires any action from our side or is purely upstream issue.

Just on the side note: this seems to be only warning and does not cause any issues right now.

Seems that the new instruction should be something along these lines

kubectl create namespace ambassador || echo "namespace ambassador exists"
helm repo add datawire https://www.getambassador.io
helm install ambassador datawire/ambassador \
	--set image.repository=quay.io/datawire/ambassador \
	--set enableAES=false \
	--set crds.keep=false \
	--namespace ambassador

There is also option to set image tag --set image.tag=$version$ but not sure which version we should choose.

The --set crds.keep=false is a flag we had previously, guess we should still leave it?
