Which version should be used? Looks like documentation is currently showing 2 different ways to configure docker registry. I wasn’t able to successfully use first one with RancherOs v0.5.0.

There are actually separate use cases for both of these.

The Docker client reads from `/home/rancher/.docker/config.json`, so the second method will configure authentication when running `docker` commands.

The first command will configure authentication for system services such as those in a cloud-config or those enabled with the `ros` command.

Thanks! Makes sense!
