It goes without saying that backing up Kubernetes Components is an essential part of any Kubernetes Administrator, especially in production environments. While it has always been possible to write a home-grown solution, we here at Rancher want to make it as easy as possible to protect your Rancher-based clusters. Not only does backing up Rancher components protect you in the event of an failed upgrade or other disasters, but it’s also a great way to migrate Rancher to a completely different cluster.

For the better part of a decade, we developers and operators have relied on the Docker Hub and their image repository for our needs. This has been great for the growth of the technology, but this growth has necessitated a change to how Docker makes money. As such, Docker is rate limiting anonymous and authenticated users.
