I inherited a Rancher cluster that was created using a docker rancher/hyperkube. The kubernetes repository up to ~v1.19 has kubernetes/hyperkube info - but it does not work with the rancher/hyperkube. On the other hand, Rancher appears to still be deveioping hyperkube. However, I cannot find any documentation on the flags that I can pass to the docker run command. The kubernetes documentation is dated since many of the flags are either deprecated or no longer valid. I appreciate it someone could pass along the information (e.g., URL or paste the info). Thanks
