How to install Cozystack using PXE

Cozystack deployment

Install dependencies:

  • docker
  • kubectl

Netboot server

Start matchbox with prebuilt Talos image for Cozystack:

sudo docker run --name=matchbox -d --net=host ghcr.io/aenix-io/cozystack/matchbox:v0.20.2 \
  -address=:8080 \
  -log-level=debug

Start DHCP-Server:

sudo docker run --name=dnsmasq -d --cap-add=NET_ADMIN --net=host quay.io/poseidon/dnsmasq:v0.5.0-32-g4327d60-amd64 \
  -d -q -p0 \
  --dhcp-range=192.168.100.3,192.168.100.199 \
  --dhcp-option=option:router,192.168.100.1 \
  --enable-tftp \
  --tftp-root=/var/lib/tftpboot \
  --dhcp-match=set:bios,option:client-arch,0 \
  --dhcp-boot=tag:bios,undionly.kpxe \
  --dhcp-match=set:efi32,option:client-arch,6 \
  --dhcp-boot=tag:efi32,ipxe.efi \
  --dhcp-match=set:efibc,option:client-arch,7 \
  --dhcp-boot=tag:efibc,ipxe.efi \
  --dhcp-match=set:efi64,option:client-arch,9 \
  --dhcp-boot=tag:efi64,ipxe.efi \
  --dhcp-userclass=set:ipxe,iPXE \
  --dhcp-boot=tag:ipxe,http://192.168.100.254:8080/boot.ipxe \
  --log-queries \
  --log-dhcp

Where:

  • 192.168.100.3,192.168.100.199 range to allocate IPs from
  • 192.168.100.1 your gateway
  • 192.168.100.254 is address of your management server

Check status of containers:

docker ps

example output:

CONTAINER ID   IMAGE                                               COMMAND                  CREATED          STATUS          PORTS     NAMES

Start your servers, now they should automatically boot from your PXE server.

Now, when they are booted to Talos Linux maintenance mode, you can use talos-bootstrap or Talm to bootstrap the cluster

Just follow Get Started guide starting from the Bootstrap cluster section, to continue the installation.
