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] +---------- + ID: curl + Function: pkg.installed + Result: True + Comment: All specified packages are already installed + Started: 22:59:00.821329 + Duration: 28.639 ms + Changes: +---------- + ID: tailscale + Function: pkg.installed + Result: True + Comment: All specified packages are already installed and are at the desired version + Started: 22:59:00.850083 + Duration: 4589.765 ms + Changes: +---------- + ID: netdata-kickstart + Function: cmd.run + Name: curl -Ss https://my-netdata.io/kickstart.sh | sh -s -- --dont-wait + Result: True + Comment: Command "curl -Ss https://my-netdata.io/kickstart.sh | sh -s -- --dont-wait" run + Started: 22:59:05.441217 + Duration: 10617.082 ms + Changes: + ---------- + pid: + 169287 + retcode: + 0 + stderr: + sh: 19: cd: can't cd to sh + --- Using /tmp/netdata-kickstart-ZtqZcfWuqk as a temporary directory. --- + --- Checking for existing installations of Netdata... --- + --- No existing installations of netdata found, assuming this is a fresh install. --- + --- Attempting to install using native packages... --- + --- Repository configuration is already present, attempting to install netdata. --- + [/tmp/netdata-kickstart-ZtqZcfWuqk]# env DEBIAN_FRONTEND=noninteractive apt-get -o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confold install -y netdata + OK + + [/tmp/netdata-kickstart-ZtqZcfWuqk]# test -x //usr/libexec/netdata/netdata-updater.sh + OK + + [/tmp/netdata-kickstart-ZtqZcfWuqk]# grep -q \-\-enable-auto-updates //usr/libexec/netdata/netdata-updater.sh + OK + + [/tmp/netdata-kickstart-ZtqZcfWuqk]# //usr/libexec/netdata/netdata-updater.sh --enable-auto-updates + Thu Dec 21 22:59:15 UTC 2023 : INFO: netdata-updater.sh: Auto-updating has been ENABLED through cron, updater script linked to /etc/cron.daily/netdata-updater + + Thu Dec 21 22:59:15 UTC 2023 : INFO: netdata-updater.sh: If the update process fails and you have email notifications set up correctly for cron on this system, you should receive an email notification of the failure. + Thu Dec 21 22:59:15 UTC 2023 : INFO: netdata-updater.sh: Successful updates will not send an email. + OK + + Successfully installed the Netdata Agent. + + Official documentation can be found online at https://learn.netdata.cloud/docs/. + + Looking to monitor all of your infrastructure with Netdata?
