title: "Road to local k8s"
date: 2020-07-13
tags: ['kubernetes', 'linux', 'fedora']
---
* Goal
The goal is to deploy kubernetes on my local networks, and keep everything as
reproducible as possible.
* Stack
I'll use Fedora Core OS, Matchbox and Terraform [fn:1], a match the requirements
for Tectonic [fn:2]
** Steps
- Network Setup DHCP/TFTP/DNS [fn:3]
- Matchbox [fn:4]
- PXE network boot environment
- Terraform Tectonic [fn:5]
** Network Setup DHCP/TFTP/DNS
First learning the basics again:
- https://linuxhint.com/install_dhcp_server_ubuntu/
- https://www.youtube.com/watch?v=XQ3T14SIlV4
To check open ports
#+BEGIN_SRC sh
lsof -Pni | grep LISTEN
#+END_SRC
Run the provided [fn:dnsmasq] image with ~dnsmasq~ and PXE toolkit
#+BEGIN_SRC sh
docker run --rm --cap-add=NET_ADMIN --net=host quay.io/coreos/dnsmasq \
-d -q \
--dhcp-range=192.168.1.3,192.168.1.254 \
--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://matchbox.example.com:8080/boot.ipxe \
--address=/matchbox.example/192.168.1.2 \
--log-queries \
--log-dhcp
#+END_SRC
** Matchbox
** PXE network boot environment
** Terraform Tectonic
