Since my containers are self maintaining and download updates on every start/restart you shouldn't have to do much, just restart it.
You can set validation to "true" but that shouldn't be necessary. Please don't forget to set ti to false after updating the container or simply leave it empty <- you never should set validation to "true", only if you have issues when updating the container.
I don't know much about V-Rising but as long as they don't change how the dedicated server is started or the binary name everything should work as always with this container, let me know if you are experiencing any issues but I think you will let me know anyways...
