Hosting guide #

A short guide to running Bonfire in a production environment and setting up a digital space connected to the fediverse.

Warning {: .warning} #

Bonfire is currently beta software. While it's fun to play with it, we would not recommend running any production instances yet (meaning not using it for your primary fediverse identity) because it's not quite ready for that today.

These instructions are for setting up Bonfire in production. If you want to run the backend in development, please refer to our Installation guide instead.

Security Warning #

We recommend only granting an account to people you trust to minimise the attack surface. Accordingly, Bonfire ships with public registration disabled. The admin panel has an invite facility.

Step 1 - Decide how you want to deploy and manage the app #

Co-op Cloud #

Install using Co-op Cloud (recommended) which is an alternative to corporate cloud services built by tech co-ops, and provides handy tools for setting up and managing many self-hosted free software tools using ready-to-use "recipes". Very useful if you'd like to host Bonfire alongside other open and/or federated projects.

  1. Install Abra on your machine
  2. Set up a server with co-op cloud
  3. Use the Bonfire recipe and follow the instructions there, including editing the config in the env file at ~/.abra/servers/your_server/your_app.env (see prepare the config for details about what to edit)
  4. Run the abra deploy command and done!

Docker containers #

  1. Install dependencies.

The easiest way to manage the docker image is using just commands.

The docker-compose.release.yml uses config/prod/.env to launch a container with the necessary environment variables along with its dependencies, currently that means an extra postgres container, along with a reverse proxy (Caddy server, which you may want to replace with nginx or whatever you prefer).

Make sure you have Docker, with the compose plugin, and just installed:

$ docker version
Docker Engine - Community - 23.0.1

$ docker compose version
Docker Compose version v2.16.0

$ just --version
just 1.13.0
...
  1. Clone this repository and change into the directory:
git clone --depth 1 https://github.com/bonfire-networks/bonfire-app.git bonfire && cd bonfire
  1. Specify what flavour you want to run in production:

The first thing to do is choose what flavour of Bonfire (eg. classic, community, or cooperation) you want to deploy, as each flavour uses different Docker images and set of configs. For example if you want to run the classic flavour:

  • export MIX_ENV=prod FLAVOUR=classic WITH_DOCKER=yes

You may also want to put this in the appropriate place in your system so your choice of flavour is remembered for next time (eg. ~/.bashrc or ~/.zshrc)

  1. Run just config to initialise some default config and then edit the config in the ./.env file (see prepare the config for details about what to edit).

Now that your tooling is set up, you have the choice of using pre-built images or building your own. For example if your flavour does not have a prebuilt image on Docker Hub, or if you want to customise any of the extensions, you can build one yourself.

Using pre-built Docker images (easy mode) #

  • The image entry in docker-compose.release.yml will by default use the image on Docker Hub which corresponds to your chosen flavour (see step 1 above for choosing your flavour).

You can see the images available per flavour, version (we currently recommend using the latest tag), and architecture at https://hub.docker.com/r/bonfirenetworks/bonfire/tags

  1. Try running the app!

Custom Docker build #

Building your own Docker image is useful if you want to make code changes or add your own extensions.

Dockerfile.release uses the multistage build feature to just the image as small as possible. It generates the OTP release which is later copied into the final image packaged in an Alpine linux container.

There is a justfile with relevant commands (make sure set the MIX_ENV=prod env variable):

  • just rel-build-locked which builds the docker image of the latest release
  • just rel-build which builds the docker image, including local changes to any cloned extensions in ./extensions/
  • just rel-tag adds the "latest" tag to your last build, so that it will be used when running

Once you've built and tagged your image, you may need to update the image name in docker-compose.release.release.yml to match (either your local image name if running on the same machine you used for the build, or a remote image on Docker Hub if you pushed it) and then follow the same steps as for option A1.

For production, we recommend to set up a CI workflow to automate this, for an example you can look at the one we currently use.

Finally, try running the app!

#### Running with Docker

  • Start the docker containers with docker-compose:
just rel-run

Run this at the prompt:

bin/bonfire remote to enter Elixir's iex environment
Bonfire.Common.Repo.migrate to initialise your database

The backend should now be running at http://localhost:4000/. Yay, you're up and running!

  • If that worked, start the app as a daemon next time:
just rel-run-bg

(Alternatively, just rel-run-bg db if you want to run the backend + db but not the web proxy, or just rel-run-bg db search if you want to run the full-text search index.)

Bare-metal #

Running a custom build without Docker.

  1. Install dependencies.
  • Postgres (or Postgis) version 12 or newer
  • just
  • Elixir version 1.15+ with OTP 25+ (see the Dockerfile to double check the versions we're currently using). If your distribution only has an old version available, check Elixir's install page or use a tool like mise (run mise install in this directory) or asdf.
  1. Clone this repository and change into the directory:
git clone --depth 1 https://github.com/bonfire-networks/bonfire-app.git bonfire && cd bonfire
  1. Specify what flavour you want to run in production:

The first thing to do is choose what flavour of Bonfire (eg. classic, community, or cooperation) you want to deploy, as each flavour uses different Docker images and set of configs. For example if you want to run the classic flavour:

  • export FLAVOUR=classic MIX_ENV=prod WITH_DOCKER=no

You may also want to put this in the appropriate place in your system so your choice of flavour is remembered for next time (eg. ~/.bashrc or ~/.zshrc)

  1. Run just config to initialise some default config and then edit the config in the ./.env file (see prepare the config for details about what to edit).

  2. Run just rel-build to create an elixir release. This will create an executable in your _build/prod/rel/bonfire directory. Note that you will need just to pass in the .env file to the executable, like so: just cmd _build/prod/rel/bonfire/bin/bonfire <bonfire command>. Alternatively, this file can be sourced by source .env instead. We will be using the bin/bonfire executable as called from just from here on.

  3. Running the release

  • Create a database, and a user, fill out the .env with your credentials and secrets

  • You will need to use just in order to pass the .env file to the executable. This can be accomplished by running just cmd _build/prod/rel/bonfire/bin/bonfire <bonfire command>. Just works from the root directory of the justfile, not your current directory.

  • If you’re using RDS or some other locked down DB, you may need to run CREATE EXTENSION IF NOT EXISTS citext WITH SCHEMA public; on your database with elevated privileges.

  • You can check if your instance is configured correctly and get to the iex console by running bin/bonfire start

  • The migrations should automatically run on first boot, but if you run into troubles the migration command is: Bonfire.Common.Repo.migrate() in the iex console.

  • To run the instance as a daemon, use bin/bonfire start daemon. Yay, you're up and running!

  1. Adding HTTPS

The common and convenient way for adding HTTPS is by using a reverse proxy like Nginx or Caddyserver (the latter of which is bundled as part of the docker compose setup).

Caddyserver and other servers can handle generating and setting up HTTPS certificates automatically, but if you need TLS/SSL certificates for nginx, you can look get some for free with letsencrypt. The simplest way to obtain and install a certificate is to use Certbot.. Depending on your specific setup, certbot may be able to get a certificate and configure your web server automatically.

If you've built from source, you should point the nginx root directory to be _build/prod/rel/bonfire/lib/bonfire-[current-version]/priv/static

Nix #

This repo contains an experimental Flake and Nix module. These are not ready for production.

Here are the detailed steps to deploy it:

  • run a recent version of Nix or NixOS: https://nixos.wiki
  • enable Flakes: https://nixos.wiki/wiki/Flakes#Installing_flakes
  • add sandbox = false in your nix.conf
  • fetch and build the app and dependencies: nix run github:bonfire-networks/bonfire-app start_iex
  • add it as an input to your system flake.
  • add an overlay to just the package available
  • add the required configuration in your system

Your flake.nix file would look like the following. Remember to replace myHostName with your actual hostname or however your deployed system is called.

{
  inputs.bonfire.url = "github:bonfire-networks/bonfire-app/main";
  outputs = { self, nixpkgs, bonfire }: {
    overlay = final: prev: with final;{
      # a package named bonfire already exists on nixpkgs so we put it under a different name
      elixirBonfire = bonfire.packages.x86_64-linux.default;
    };
    nixosConfigurations.myHostName = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        {
          environment.systemPackages = [ agenix.defaultPackage.x86_64-linux ];
          nixpkgs.overlays = [ self.overlay ];
        }
        ./myHostName.nix
        bonfire.nixosModules.bonfire
      ];
    };
  };
}

Then your myHostName.nix would look like the following:

{ config, lib, pkgs, ... }:

{
  services.bonfire = {
    # you will additionally need to expose bonfire with a reverse proxy, for example caddy
    port = 4000;
    package = pkgs.elixirBonfire;
    dbName = "bonfire";
    # the environment should contain a minimum of
    #   SECRET_KEY_BASE
    #   SIGNING_SALT
    #   ENCRYPTION_SALT
    #   RELEASE_COOKIE
    # have a look into nix/module.nix for more details
    # the way to deploy secrets is beyond this readme, but I would recommend agenix
    environmentFile = "/run/secrets/bonfireEnv";
    dbSocketDir = "/var/run/postgresql";
  };
	
	# this is specifically for a reverse proxy, which is primarily used for SSL certs
	services.ngnix = {
		enable = true;
		forceSSL = true;
		enableACME = true;
		virtualHosts."myHostName".locations.proxyPass = "http://localhost:4000";
	};
	
	# You will need to accept ACME's terms and conditions if you haven't elsewhere in your configuration
	security.acme.defaults.email = "you@myHostName.com";
	security.acme.acceptTerms = true;

  # this is uniquely for database backup purposes
  # replace myBackupUserName with the user name that will do the backups
  # if you want to do backups differently, feel free to remove this part of the config
  services.postgresql = {
    ensureDatabases = [ "bonfire" ];
    ensureUsers = [{
      name = "myBackupUserName";
      ensurePermissions = { "DATABASE bonfire" = "ALL PRIVILEGES"; };
    }];
  };
}

## Preparing the config (in .env)

Config keys you should pay special attention to: #

The app needs these environment variables to be configured in order to work.

  • FLAVOUR should reflect your chosen flavour
  • HOSTNAME (your domain name, eg: bonfire.example.com)
  • PUBLIC_PORT (usually 443)
  • MAIL_DOMAIN and MAIL_KEY and related keys to configure transactional email, for example set MAIL_BACKEND=mailgun and sign up at Mailgun and then configure the domain name and key (you may also need to set MAIL_BASE_URI if your domain is not setup in EU, as the default MAIL_BASE_URI is set as https://api.eu.mailgun.net/v3).
  • SMTP is supported as well, through the following env vars
MAIL_SERVER (smtp domain of the mail server)
MAIL_DOMAIN (the bit after the @ in your email)
MAIL_USER
MAIL_PASSWORD
MAIL_FROM
MAIL_PORT (optional)
MAIL_SSL (optional)
  • UPLOADS_S3_BUCKET and the related API key and secret for uploads. WARNING: If you want to store uploads in an object storage rather than directly on your server (which you probably want, to not run out of space), you need to configure that up front, otherwise URLs will break if you change it later. See config/runtime.exs for extra variables to set if you're not using the default service and region (which is Scaleway Paris).

Secret keys for which you should put random secrets. #

You can run just secrets to generate some for you.

  • SECRET_KEY_BASE
  • SIGNING_SALT
  • ENCRYPTION_SALT
  • POSTGRES_PASSWORD
  • MEILI_MASTER_KEY

Further information on config #

In the ./config/ (which is a symbolic link to the config of the flavour you choose to run) directory of the codebase, there are following config files:

  • config.exs: default base configuration, which itself loads many other config files, such as one for each installed Bonfire extension.
  • prod.exs: default extra configuration for MIX_ENV=prod
  • runtime.exs: extra configuration which is loaded at runtime (vs the others which are only loaded once at compile time, i.e. when you build a release)
  • bonfire_*.exs: configs specific to different extensions, which are automatically imported by config.exs

You should not have to modify the files above. Instead, overload any settings from the above files using env variables or in ./.env. If any settings in the .exs config files are not available in env or in the instance settings UI, please open an issue or PR.

Running the app #

NOTE: If you are running in a restricted environment such as Amazon RDS, you will need to execute some sql against the database before migrations can run: CREATE EXTENSION IF NOT EXISTS citext;

By default, the backend listens on port 4000 (TCP), so you can access it on http://localhost:4000/ (if you are on the same machine). In case of an error it will restart automatically.

Once you've signed up, you will automatically be an instance admin if you were the first to register.

You can sign up via CLI by entering something like this in your app's Elixir console: Bonfire.Me.make_account_only("my@email.net", "my pw")

Handy commands #

  • just update to update to the latest release of Bonfire
  • just rel-run Run the app in Docker, in the foreground
  • just rel-run-bg Run the app in Docker, and keep running in the background
  • just rel-stop Stop the running release
  • just rel-shell Runs a simple shell inside of the container, useful to explore the image

Once in the shell, you can run bin/bonfire with the following commands:
Usage: bonfire COMMAND [ARGS]

The known commands are:

  • start Starts the system
  • start_iex Starts the system with IEx attached
  • daemon Starts the system as a daemon
  • daemon_iex Starts the system as a daemon with IEx attached
  • eval "EXPR" Executes the given expression on a new, non-booted system
  • rpc "EXPR" Executes the given expression remotely on the running system
  • remote Connects to the running system via a IEx remote shell
  • restart Restarts the running system via a remote command
  • stop Stops the running system via a remote command
  • pid Prints the operating system PID of the running system via a remote command
  • version Prints the release name and version to be booted

There are some useful database-related release tasks under EctoSparkles.Migrator. that can be run in an iex console (which you get to with just rel.shell followed by bin/bonfire remote, assuming the app is already running):

  • migrate runs all up migrations
  • rollback(step) roll back to step X
  • rollback_to(version) roll back to a specific version
  • rollback_all rolls back all migrations back to zero (caution: this means losing all data)

You can also directly call some functions in the code from the command line, for example:

  • to migrate: docker exec bonfire_web bin/bonfire rpc 'Bonfire.Common.Repo.migrate'
  • to just yourself an admin: docker exec bonfire_web bin/bonfire rpc 'Bonfire.Me.Users.make_admin("my_username")'

Admin tools #

  • LiveDashboard for viewing real-time metrics and logs at /admin/system/
  • Oban logs for viewing queued jobs (e.g. for processing federated activities) /admin/system/oban_queues
  • LiveAdmin for browsing data in the database at /admin/system/data
  • Orion for dynamic distributed performance profiling at /admin/system/orion
  • Web Observer as an alternative way to view metrics at /admin/system/wobserver

Troubleshooting #

Some common issues that may arise during deployment and our suggestions for resolving them.

WebSocket connections not establishing behind a reverse proxy #

If you are running Bonfire behind your own reverse proxy (e.g. nginx), you might experience issues with WebSocket connections not establishing. WebSocket connections require specific configuration to work, in nginx the following configuration is necessary for websockets to work:

location /live/websocket {
    proxy_pass http://127.0.0.1:4000;
    
    # these configurations are necessary to proxy WebSocket requests
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}
