As a follow-up to my recent explorations [1] with using Tailscale Serve to make netdata [2] monitoring readily available on my tailnet [3], I wanted a quick way to reproduce that configuration across my handful of systems. These systems already have Tailscale installed [4] and configured, and they're all managed with Salt [5].
So here's a hasty Salt state that I used to make it happen.
It simply installs netdata using the handy-dandy kickstart script [6], and then configures Tailscale to Serve the netdata instance (with a trusted cert!) inside my tailnet over `https://[hostname].[tailnet-name].ts.net:8443/netdata`.
[6] handy-dandy kickstart script
# -*- coding: utf-8 -*-
# vim: ft=sls
# Hasty Salt config to install Netdata and make it available within a tailnet
# at https://[hostname].[tailnet-name].ts.net:8443/netdata
curl:
pkg.installed
tailscale:
pkg.installed:
- version: latest
netdata-kickstart:
cmd.run:
- name: curl -Ss https://get.netdata.cloud/kickstart.sh | sh -s -- --dont-wait
- require:
- pkg: curl
# don't run this block if netdata is already running
- unless: pgrep netdata
tailscale-serve:
cmd.run:
- name: tailscale serve --bg --https 8443 --set-path /netdata 19999
- require:
- pkg: tailscale
- cmd: netdata-kickstart
# don't run this if netdata is already tailscale-served
- unless: tailscale serve status | grep -q '/netdata proxy http://127.0.0.1:19999'
It's not super elegant... but it got the job done, and that's all I needed it to do.
