How to invoke sonatype nexus docker insecure registry as a secret in kubernetes

Question

Ex: docker registry url : registry.example.com:8056 within nexus docker (hosted). Need to configure this as a secret in kubernetes to pull images from the docker hosted registry.

I tried by adding insecure registry in the worker nodes on the path /etc/docker/daemon.json as

{"insecure-registries" : ["http://registry.example.com:8056"]}

but no luck.
