Hello,
Unless I'm mistaken, there is no "out-of-the-box" solution.
A way to do it would be an active/sdandby with keepalived + virtual IP + HA Redis setup.
With Kubernetes, it could be possible, but I'm not sure it's well suited for a wide port range (usually 10000 UDP ports), but I'm interested if somebody has already experience with it.
Kind regards,
Mathieu Bodjikian
