How do I get k3s to authenticate with Docker Hub?

[meriah]

In jornalctl -u k3s, I see a bunch of errors like this

429 Too Many Requests - Server message: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

When I check the associate pods, I see

Error from server (BadRequest): container "foo" in pod "bar" is waiting to start: trying and failing to pull image

How can I set up k3s to use an authenticate login to DockerHub? I don't see a docker login, and I've tried probably 20 different things none of which worked. I can confirm this username and password works with https://devops.stackexchange.com/q/16152/18965 . But it doesn't work when I try to put it in a config file. I've tried to playing with

• /etc/rancher/k3s/registries.yaml and restarting.
• that seems to generate a new /var/lib/rancher/k3s/agent/etc/containerd/config.toml, I've tried playing with that file too directly

None of this seems to make any difference. I've tried testing with k3s kubectl run and also with https://devops.stackexchange.com/q/16152/18965 , and none of these change the error that's returned.

1. Update your /etc/rancher/k3s/registries.yaml to

   configs:
     registry-1.docker.io:
       auth:
         username: evancarroll
         password: TOKENHIDDEN
   

2. Restart k3s, sudo systemctl force-reload k3s.

You can confirm the changes were accepted by checking that your key exists in /var/lib/rancher/k3s/agent/etc/containerd/config.toml.
