- <blockquote>
- [Ansible-Pull] is used to up a remote copy of ansible on each managed

- </blockquote>
- </p>
- <p>
- The goal is to pull and run a playbook remotely using a git repository. The
- playbook will describe the tasks needed to setup our machine from scratch.
- <br/>
- But first lets tinker a bit a with playbooks locally with ansible-playbook,
- to do so we need to add localhost to ansible's hosts list. Add it to
- /etc/ansible/hosts:
-<pre><code>[all]
-localhost</code></pre>
- </p>
- <p>
- As an experiment we're going to write a asks to install vim. Currently, I'm
- using Fedora thus we going to use dnf modeule to install packages, but if
- you're using another distribution look for a equivalent module like apt
- module for Ubuntu.
-
- The playbook to install is quite simple:
-
-<pre><code># main.yaml
-- hosts: all
- tasks:
- - name: install vim
- dnf:
- name: vim
- state: latest</code></pre>
- <dl>
- <dt>host</dt>
- <dd>it is required and it has to match our hosts otherwise the playbook won't run.</dd>

- <dd>
- it is the list of tasks that the playbook will perform, in this case
- will be dnf install vim.
- </dd>
- </dl>
- </p>
- <p>
- To run a playbook use the command ansible-playbook commando to run main.yml
- direct from disk, do to so just run the following command:
-<pre><code>sudo ansible-playbook --connection=local main.yml</code></pre>

+In the `.vimrc` add your own configuration, you can see mine [over

+# 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 [^1], a match the
+requirements for Tectonic [^2]
+
+## Steps
+
+- Network Setup DHCP/TFTP/DNS [^3]
+- Matchbox [^4]
+- PXE network boot environment
+- Terraform Tectonic [^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
+
+``` {.bash org-language="sh"}
+lsof -Pni | grep LISTEN
+```
+
+Run the provided [^6] image with `dnsmasq` and PXE toolkit
+
+``` {.bash org-language="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 \
