If you have done a rancher login on the host, you can map the .rancher folder into the container to share credentials.
docker run -rm -it -v ~/.rancher:/root/.rancher mheiniger/rancher-cli-k8s:latest rancher kubectl get nodes
Otherwise, you'll need to login using an API token from your rancher gui. In a build scenario You could create a new API key from your account in the rancher2 GUI and then expose it via environment variable and then:
rancher login "$RANCHER_SERVER_URL" -t "$RANCHER_API_TOKEN"
rancher kubectl get nodes
