 7# Goal
 8
 9The goal is to deploy kubernetes on my local networks, and keep everything as
10reproducible as possible.
11
12# Stack
13
14I\'ll use Fedora Core OS, Matchbox and Terraform [^1], a match the requirements
15for Tectonic [^2]
16
17## Steps
18
19-   Network Setup DHCP/TFTP/DNS [^3]
20-   Matchbox [^4]
21-   PXE network boot environment
22-   Terraform Tectonic [^5]
23
24## Network Setup DHCP/TFTP/DNS
25
26First learning the basics again:
27
28-   <https://linuxhint.com/install_dhcp_server_ubuntu/>
29-   <https://www.youtube.com/watch?v=XQ3T14SIlV4>
30
31To check open ports
32
33```shell
34lsof -Pni | grep LISTEN
35```
36
37Run the provided [^6] image with `dnsmasq` and PXE toolkit
38
39``` {.bash org-language="sh"}
40docker run --rm --cap-add=NET_ADMIN --net=host quay.io/coreos/dnsmasq \
41  -d -q \
42  --dhcp-range=192.168.1.3,192.168.1.254 \
43  --enable-tftp --tftp-root=/var/lib/tftpboot \
44  --dhcp-match=set:bios,option:client-arch,0 \
45  --dhcp-boot=tag:bios,undionly.kpxe \
46  --dhcp-match=set:efi32,option:client-arch,6 \
47  --dhcp-boot=tag:efi32,ipxe.efi \
48  --dhcp-match=set:efibc,option:client-arch,7 \
49  --dhcp-boot=tag:efibc,ipxe.efi \
50  --dhcp-match=set:efi64,option:client-arch,9 \
51  --dhcp-boot=tag:efi64,ipxe.efi \
52  --dhcp-userclass=set:ipxe,iPXE \
53  --dhcp-boot=tag:ipxe,http://matchbox.example.com:8080/boot.ipxe \
54  --address=/matchbox.example/192.168.1.2 \
55  --log-queries \
56  --log-dhcp
