Network Boot and Provision CoreOS Clusters (etcd, Kubernetes, etc.)

CoreOS on Baremetal

CoreOS on Baremetal contains guides for network booting and configuring CoreOS clusters on virtual or physical hardware.

bootcfg

bootcfg is a HTTP and gRPC service that renders signed Ignition configs, cloud-configs, network boot configs, and metadata to machines based on attribute labels (e.g. UUID, MAC, stage, region) to create CoreOS clusters. Network boot endpoints provide PXE, iPXE, GRUB, and Pixiecore support. bootcfg can run as an ACI with rkt, as a Docker container, or as a binary.

Examples

Check the examples to find Profiles for booting and provisioning machines into higher-order CoreOS clusters. Network boot libvirt VMs to try the examples on your Linux laptop.

• Multi-node Kubernetes cluster with TLS (network booted or installed to disk)
• Multi-node etcd cluster (network booted or installed to disk)
• Multi-stage CoreOS installs
• GRUB Netboot CoreOS
• iPXE Boot CoreOS with a root fs
• iPXE Boot CoreOS
