CoreOS on Baremetal

Guides and a service for network booting and provisioning CoreOS clusters on virtual or physical hardware.

bootcfg

bootcfg is an HTTP and gRPC service that renders signed Ignition configs, cloud-configs, network boot configs, and metadata to machines to create CoreOS clusters. Groups match machines based on labels (e.g. MAC, UUID, stage, region) and use named Profiles for provisioning. Network boot endpoints provide PXE, iPXE, and GRUB. bootcfg can be deployed as a binary, as an appc container with rkt, or as a Docker container.

Examples

The examples network boot and provision CoreOS clusters. Network boot libvirt VMs to try the examples on your Linux laptop.

• Multi-node Kubernetes cluster
• Multi-node Kubernetes cluster with rkt container runtime (i.e. rktnetes)
• Multi-node self-hosted Kubernetes cluster
• Multi-node etcd2 or etcd3 cluster
• Multi-node Torus distributed storage cluster
• Network boot or Install to Disk
• Multi-stage CoreOS installs
• GRUB Netboot CoreOS
• iPXE Boot CoreOS with a root fs
• iPXE Boot CoreOS
