ansible-ztp-onie

This playbook provides DHCP and a webserver for ZTP and reimaging of ONIE based switches. It's goal is to aid bootstrapping switches for further programmatic configuration, e.g. ansible.

It makes use of:

• halverneus/static-file-server
• wastrachan/docker-dhcpd

The webserver is exposed on 8080/tcp

The playbook has been tested on:

• Rocky Linux 9 host
• Migration of Cumulus Linux 5.6 -> 5.11

TODO

This met the minimum requirements, but could be improved upon Initial thoughts:

• Template ZTP script
  • Move vars to ansible
  • Read public key(s) from file(s)

Dependencies

• The playbook is expected to be run against localhost.
• Localhost sits on the same L2 domain as the switch(es).
• There are no other DHCP servers in this L2 domain.
• (Optional) The MAC address of the mgmt interface is known.

Quickstart

• Clone the repo
• Adjust values in defaults/main.yml
  • It is suggested to delegate fixed switch IPs outside of the dynamic DHCP range. This ensures any rogue DHCP client is non-interfering.
• A venv is recommended.

python -m venv provision
source provision/bin/activate
pip install -r requirements.txt
ansible-galaxy install -r requirements.yml

• Customise the ZTP script and/or place an ONIE image in the serve directory
