Originally posted as an issue.
There are two ways to cirumvent this issue.
istioctl installUsing istioctl install provide a secret with docker-registry auth details with --set values.global.imagePullSecrets. Like this
istioctl install [other options] --set values.global.imagePullSecrets[0]=<auth-secret>Where <auth-secret> is the secret created prior on the cluster.
You can read more about using secrets with docker repository here
Installing Istio with operator, from private regostry, you have to pass proper YAML:
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
...
spec:
profile: demo #as an example
values:
global:
imagePullSecrets:
- <auth-secret>
...
Again, <auth-secret> must be created prior.
