Currently docker images were pulled from public registries during
config_controller. For some users, the connection to the public
docker registry may be slow such that installing the containerized
services images may timeout or the system simply does not have
access to the public internet.
This change allows users to specify alternative public/private
registries to replace k8s.gcr.io, gcr.io, quay.io and docker.io.
Insecure registry is supported if all default registries were
replaced by one unified registry. It lowers the complexity for
those who build his own registry without internet access.
Docker doesn't support ipv6 addr as registry name, instead
hostname or domain name in ipv6 network is allowed.
Test:
AIO-SX/AIO-DX/Standard(2+2):
Alternative public registry (ipv4/domain) with proxy
- config_controller pass
Private registry (ipv4/ipv6/domain) without internet
- config_controller pass
Default registry with/without proxy
- config_controller pass
