As a follow-up to my [recent explorations](/tailscale-ssh-serve-funnel) with using Tailscale Serve to make [netdata](https://github.com/netdata/netdata) monitoring readily available on my [tailnet](https://tailscale.com/kb/1136/tailnet), I wanted a quick way to reproduce that configuration across my handful of systems. These systems already have [Tailscale installed](https://tailscale.com/download/linux) and configured, and they're all [managed with Salt](https://docs.saltproject.io/en/getstarted/).
|
||||
|
||||
So here's a hasty Salt state that I used to make it happen.
|
||||
|
||||
It simply installs netdata using the [handy-dandy kickstart script](https://learn.netdata.cloud/docs/installing/one-line-installer-for-all-linux-systems), 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`.
|
||||
|
||||
|
||||
```yaml
|
||||
# torchlight! {"lineNumbers": true}
|
||||
# -*- coding: utf-8 -*-
|
||||
# vim: ft=sls
|
||||
# Hasty Salt config to install Netdata and make it available within a Tailscale 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://my-netdata.io/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.
|
||||
|
||||
```shell
|
||||
sudo salt 'minion-name' state.apply netdata # [tl! .cmd focus]
|
||||
minion-name: # [tl! .nocopy:start collapse:start]
