Requirements for a bootstrap node¶
A bootstrap 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 of a baremetal-based bootstrap seed node are described in System requirements for the seed node. The minimum reference system requirements a bootstrap node for other supported Container Cloud providers are as follows:
Any local machine on Ubuntu 20.04 that requires access to the provider API with the following configuration:
4 GB of RAM
5 GB of available storage
Docker version currently available for Ubuntu 20.04
Internet access for downloading of all required artifacts
For the vSphere cloud provider, you can use RHEL 7.9 as the operating system for the bootstrap node. The system requirements are the same as for Ubuntu.
For the Equinix Metal cloud provider with private networks, a bootstrap node must be attached to the VLAN that will be used to deploy a management cluster.
