I need to block all registries and allow only one private registry for docker to pull images from , how can that be done natively in docker.
Just found in redhat docs:
This can be done on docker daemon config:
/etc/sysconfig/docker
BLOCK_REGISTRY='--block-registry=all'
ADD_REGISTRY='--add-registry=registry.access.redhat.com'
and then do:
systemctl restart docker
