Analysis:
Try to pull image directly by:
[root@mstnode ~]# docker pull docker.io/istionightly/istio-ca:0.7.1
Error response from daemon: manifest for istionightly/istio-ca:0.7.1 not found
The reason is that default image repository defined in value.yaml isn't updated.
Confirm it by running:
[root@mstnode ~]# docker pull docker.io/istio/istio-ca:0.7.1
