Install our IdP and VPN

I have extensive articles on installing Authentik, Netbird, NGinX Proxy Manager, Docker, and Docker Compose.  So this article is really dedicated to the configuration of Netbird to use Authentik as our IdP (Identity Provider).

What You'll Need

  • A few VPS, or VMs on which to host these services.
  • Docker and Docker Compose installed on each server (I have a script for that)
  • A domain name for which you can create sub-domains, and set A Records in DNS
  • About an hour of time.

Setup your VMs or VPS

It will be extremely important that you setup your VPS / VMs appropriately for the workload you'll be putting on them. Also, the ability to sscale those up over time will be important as well.  In the video, I use Digital Ocean for this purpose, but you are welcome to use any provider you wish, or your own hardware of course. 

Keep in mind: Your clients will be depending on you to keep your, and their, services up and running at all times.  If you use your own hardware in side your home / business, make sure you have redundancy in mind for power, connectivity, and so on.

Installation of Docker and Docker Compose via a Simple Script

You should setup your first VM / VPS for NGinX Proxy Manager (NPM from this point on) / (if you don't already have it).  Make sure that you have ports 80 and 443 accessible.  Initially, you'll also need port 81, as this is where the NPM admin user interface runs.  We'll create a proxy to this port, then close this port afterward (see my video for this procedure).  The server should have 1 vCPU and 512 MB RAM.

You can easily install Docker-CE, Docker-Compose, Portainer-CE, and NGinX Proxy manager by using this quick install script I created and maintain on Github.  Just use the command:

wget -O

To download the script to your desired host.

Change the permissions to make the script executable:

chmod +x ./

and then run the script with the command:


When run, the script will prompt you to select your host operating system, then will ask you which bits of software you want to install.

Simply enter 'y' for each thing you want to install.

At some point, you may be asked for your super user (sudo) password as well.

Allow the script to complete installation.

At this point, you might want to log out and back in, as this will allow you to use the docker and docker-compose commands without the need of sudo in front of them.

Install Authentik

For this server, I used a 1 vCPU and 2GB RAM VPS.  This should give us decent performance, as well as some room to grow over time before needing to upsize.

For Authentik, we really just followed my original guide, and didn't have to make any specific changes.

Install Netbird with Authentik as the IdP

As always, you should really check the Netbird official documentation to ensure no major changes have occurred in their install and setup steps since this article was written.  When in doubt, always go to the source.

Firs,t we'll be using another VPS with 1 vCPU and 2 GB RAM for this install.  Additionally, we'll be using the "advanced" guide fot eh netbird install.  This guide is pretty straight forward.  First giving you instructions on how to get the proper / latest version of the Netbird server available.

NOTE: Netbird, by default, ships with the Zitadel IdP server as part of their "Quick install" solution.  This is shown in my original Netbird video, so feel free to use that, and Zitadel as your IdP if you prefer. 

We again, need to start with install Docker and Docker Compose. Once that's done, we need to get Netbird ready. This will be heavily taken from the Netbird documentation, again, make sure to check that as the source of truth.

First, let's run these lines to grab the Repository and Version we need to download.

export REPO=""

export LATEST_TAG=$(basename $(curl -fs -o/dev/null -w %{redirect_url} ${REPO}releases/latest))

To test that our commands worked, we can echo out the values of the two variables we just set:

echo $REPO


Those should each give you some output below the command.  Next, we'll clone the repository from Github.

git clone --depth 1 --branch $LATEST_TAG $REPO

Now we should have a new folder called 'netbird' in the current directory.  We need to move into that folder, and then into the folder inside of of called 'infrastructure_files'.

cd netbird/infrastructure_files

Here, we want to copy the 'setup.env.example' file to a new file called 'setup.env'. 

cp setup.env.example setup.env

Now we can edit the new 'setup.env' file, but still have the original example file to fall back on if needed.

nano setup.env

Here's my example file. You'll want to copy / paste this to your setup.env, and then change the values as stated below the file.  Part of this is setting up a Provider and Application for Netbrid in Authentik.

## example file, you can copy this file to setup.env and update its values

# Image tags
# you can force specific tags for each component; will be set to latest if empty

# Dashboard domain. e.g.

# TURN server domain. e.g.
# if not specified it will assume NETBIRD_DOMAIN

# TURN server public IP address
# required for a connection involving peers in
# the same network as the server and external peers
# usually matches the IP for the domain set in NETBIRD_TURN_DOMAIN

# -------------------------------------------
#  e.g.,
# -------------------------------------------
NETBIRD_AUTH_SUPPORTED_SCOPES="openid profile email offline_access api"


# -------------------------------------------
# Letsencrypt
# -------------------------------------------
# Disable letsencrypt
#  if disabled, cannot use HTTPS anymore and requires setting up a reverse-proxy to do it instead
# e.g.
# -------------------------------------------
# Extra settings
# -------------------------------------------
# Disable anonymous metrics collection, see more information at
# DNS DOMAIN configures the domain name used for peer resolution. By default it is netbird.selfhosted

In the setup.env file, make sure you fill out the NETBIRD_DOMAIN with your intended domain / sub-domain name.

Additionally, you need to put in a public IPv4 address for the server where Netbird is running if you'll be relying on their coturn server which is setup automatically (I suggest this).  If you want to use your own coturn server, you can, but you need to modify the resulting 'management.json' file with the appropriate details for communicating with and through your coturn server (I don't recommend this). 

If you are using the Netbird created coturn server, you can leave the TURN_SERVER_DOMAIN blank (just empty double quotes "").  If, however, you are using your own coturn server, you need to fill in the domain name for that server here.

Next, you need to create a provider and application entry in Authentik for Netbird.  Start with the provider.

  • In Authentik go to Administrator
  • Click to expand the Applications section
  • Click 'Providers', and then select to create a new Provider in the Main UI
  • Select OpenID/OAuth Provider and click Next.
  • Fill out the form with the values
    • Name: Netbird
    • Authentication Flow: Default Authentication Flow
    • Authorization Flow: Default Authorization Flow (explicit option).
    • Under Protocol Settings select:
      • 'Public'
      • Redirect URIs: https://<domain>, https://<domain>.*, http://localhost:53000
        • Make sure to enter each of those on a separate line, without commas.
      • Signing Key: Select the Signing Key, or feel free to use the Self-signed Key.
    • Advanced protocol settings:
      • Access code validity: minutes=10
      • Subject mode: Based on the User's ID

Click 'Finish'.

Next, we need to create an Application to go with this Provider.  In the left menu, under Application, click the Applications sub-option.

In the main page interface, give the Application a name of 'Netbird'.  Make sure to set the slug to 'netbird', then choose 'Netbird' from the Provider drop-down selection list.  Additionally, under 'UI Settings', you can add the Netbird logo, as this helps make the Authentik application a little better for you and your end users (IMO).

Click 'Create'.

Now, we need to create a service user.   Click on 'Directory' in the left menu, then select 'Users' underneath it.

In the main user interface, click the button at the top that says 'Create Service Account'. 

Put in 'Netbird' for the username, and then disable the option for 'Create Group'. 

Click 'Create'. Next, you'll see a window with your newly create service account user, and a password generated by Authentik.  Copy this username and password information into a secure password manager.  You'll need these values in your 'setup.env' file for the values of NETBIRD_IDP_MGMT_EXTRA_USERNAME and NETBIRD_IDP_MGMT_EXTRA_PASSWORD.

Finally, we need to add the service account we just created to the admin group in Authentik.

On the left menu, under 'Directory', select the 'Groups' option.   In the 'Groups' view on the main user interface, select the 'authentik Admins' group by clicking on it.  At the top of the window that opens, select the 'Users' tab.  Click 'Add existing user', and click the '+' icon, and pick the 'Netbird' service account you just created.

Disable the 'Hide Service-accounts' option at the top of the view, and verify that Netbird ahs been added as an admin.

Whew! Done with Authentik setup now.

Go back to the Application >> Providers option in the left menu, and click the 'Netbird' title for the Netbird provider we created earlier.  In the window that opens, select the 'OpenID Configuration URL' and copy the entire URL.  Paste this value into your setup.env for the environment variable labeled 'NETBIRD_AUTH_OIDC_CONFIGURATION_ENDPOINT'.

Next, copy the 'Client ID' from the Authentik provider view.  Paste this value in the setup.env for the following environment variables:






Finally, make sure you fill in the NETBIRD_IDP_MGMT_EXTRA_USERNAME and NETBIRD_IDP_MGMT_EXTRA_PASSWORD with the username 'Netbird' and the password that was generated by Authentik when you added the Netbird user.

Enter your email address for the LetsEncrypt certificate section, then save the file with CTRL + O, press Enter to confirm, and CTRL + X to exit the nano editor.

Build your files to run Netbird

Now that we have filled out our setup.env file, we need to run the script that Netbird provides for creating our docker-compose.yml and two other setup files we'll need.  To do this, just run the following command in the terminal:


The output should be a long list of environment varialbes, and where they are being set, as well as what they are being set to. 

Now, let's move into the 'artifacts' folder. This is where those files are create by the '' script for us. 

cd artifacts

Here, you can do an ls and see the files that are created for us.  The 'management.json' and 'turnserver.conf' files are two important ones.  You don't need to modify anything in these files, but if you are having trouble getting Netbird to start, and function properly, you may need to check the turn user and password in each, to ensure they match.

Before we try to bring up our Netbird server, let's check one more thing.  We want to be sure that our hostname in the /etc/hosts file is set correctly.

sudo nano /etc/hosts

This will open the 'hosts' file, and you want to look for a line that may start with the ip address  If you have this line (not to be confused with the line that has, then you need to make sure that this IP is updated to be your public IP address, and that the hostname / domain are correct for your Netbird server.  In my example on the video I had nb

I had to change this value to be the public IP address of my server, so it looked more like nb

If you need to make an edit, save your changes with CTRL + O, then press Enter to confirm, and next use CTRL + X to exit the nano editor. 

Now we are ready to bring up our Netbird server with our Authentik IdP. 

docker compose up -d && docker compose logs -f

The command(s) above tell docker to pull down the images and start the containers for Netbird, and to show us the log output as the containers begin to run. 

You can look for any ERRO or ERROR messages in the logs, but they fly by pretty quickly.  Give Netbird a couple fo minutes to finish it's initial startup and setup, then navigate to the domain you setup for Nebird in your browser.   You should see the initial Netbird loading screen, then be redirected to your Authentik instance to log in, and after a successful authentication be re-directed back to your Netbird admin screen to start adding clients to your VPN.
