We have docker based ELK setup with 17 nodes among which 4 nodes are hot nodes. Docker containers for all 4 hot nodes are on the same machine. The machine also contains one hyper node and one kibana docker container.
Due to some issues, we need to reboot the machine. So what are the things to take care to reboot the machine. As all 4 hot nodes are on the same machine, no hot nodes will be available during reboot. Will there be any effect of this on shard allocation ?
Please suggest the correct approach. Any help is appreciated.
