System requirements for the seed node¶
The seed node is necessary only to deploy the management cluster. When the bootstrap is complete, the bootstrap node can be redeployed and its resources can be reused for the managed cluster workloads.
The minimum reference system requirements for a baremetal-based bootstrap seed node are as follows:
Basic server on Ubuntu 18.04 with the following configuration:
Kernel version 4.15.0-76.86 or later
8 GB of RAM
10 GB of free disk space for the bootstrap cluster cache
No DHCP or TFTP servers on any NIC networks
Routable access IPMI network for the hardware servers. For more details, see Host networking.
Internet access for downloading of all required artifacts
