Quick Salt State to Deploy Netdata 2023-12-21 2024-02-03 A hasty Salt state to deploy netdata monitoring and publish it internally on my tailnet with Tailscale Serve false true true Code
homelab
iac
linux
salt
tailscale

As a follow-up to my recent explorations with using Tailscale Serve to make netdata monitoring readily available on my tailnet, I wanted a quick way to reproduce that configuration across my handful of systems. These systems already have Tailscale installed and configured, and they're all managed with Salt.

So here's a hasty Salt state that I used to make it happen.

It simply installs netdata using the handy-dandy kickstart script, 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.

# torchlight! {"lineNumbers": true}
# -*- 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.
