Installing Authelia on Clear Linux Latest

Authelia is an open-source authentication and authorization server that provides a lot of features, including Single sign-on (SSO), 2FA, and Role-based access control (RBAC).

In this tutorial, we will guide you through the process of installing Authelia on Clear Linux Latest.

Prerequisites

• A Clear Linux machine
• A non-root user with sudo privileges

Step 1: Install Docker

Authelia is available as a Docker container. Therefore, the first step is to install Docker on Clear Linux.

1. Use the following command to enable Docker.

sudo swupd bundle-add containers-basic

2. Then, start the Docker service using the following command.

sudo systemctl start docker

3. Finally, add your user to the Docker group.

sudo usermod -a -G docker <username>

Step 2: Pull the Authelia Docker Container

Now that Docker is installed on your machine, the next step is to pull the Authelia image from Docker hub.

Run the following command to download the container.

sudo docker pull authelia/authelia

Step 3: Configure Authelia

In this step, we will configure the Authelia server.

1. Create a directory and switch into it.

mkdir authelia && cd authelia

2. Then, create a configuration file for Authelia.

nano config.yml

3. Paste the following configuration:

authelia:
  session:
    secret: "my secret key"
  authentication_backend:
    ldap:
      host: "ldap://myldapserver:389"
      user_base_dn: "ou=users,dc=my-domain,dc=com"
      user_search_filter: "(uid=%s)"
      group_base_dn: "ou=groups,dc=my-domain,dc=com"
      group_search_filter: "(memberUid=%s)"
  authorization_backend:
    ldap:
      host: "ldap://myldapserver:389"
      user_base_dn: "ou=users,dc=my-domain,dc=com"
      user_search_filter: "(uid=%s)"
      group_base_dn: "ou=groups,dc=my-domain,dc=com"
      group_search_filter: "(memberUid=%s)"
  storage:
    postgres:
      host: "mydbserver"
      username: "myuser"
      password: "mypassword"
      database: "mydatabase"
  smtp:
    host: "mysmtpserver"
    port: 25

This is a sample configuration file that you can modify to suit your environment. In this file, you need to replace the values with the correct ones for your LDAP server, database server, and SMTP server.

4. After you have saved the configuration file, start the Authelia container by running the following command.

sudo docker run -p 8080:8080 -p 443:443 --mount type=bind,source="$(pwd)"/config.yml,target=/config.yml authelia/authelia

This command will start the Authelia container and map the container's HTTP and HTTPS ports to the host's ports. It also binds the configuration file to the container's /config.yml file.

Conclusion

In this guide, we have shown you how to install and configure Authelia on Clear Linux. Now you can access the Authelia server by visiting https://localhost.

If you want to run Authelia in production, you will likely need to adjust the configuration file to fit your environment. Good luck!

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
