Outline

Outline is a modern web based wiki and knowledge base for teams.

Setup

The most minimal local installation of Outline can be enabled with the following configuration

Note: Previous example used the mockPassword connector, which is an undocumented configuration option in Dex, used solely to run some tests. Use staticPasswords configuration instead, which allows using a hash for the password and setting a real email for the user which can be used to send notifications if an SMTP server is configured. Keep in mind, if you created your first user with the previous method (mockPassword), that user is your only admin user and you need to keep it around in order to confer admin privileges to the next user.

/etc/nixos/configuration.nix

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

networking.extraHosts = ''
  127.0.0.1 dex.localhost
'';

services = {

  outline = {
    enable = true;
    publicUrl = "http://localhost:3000";
    forceHttps = false;
    storage.storageType = "local";

Outline is available at http://localhost . Choose login provider "Dex" and authenticate with the example mock login user.email@example.com and password.

SSL example

Similar as before but this time with Nginx handling SSL.

/etc/nixos/configuration.nix

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

  services.nginx = {
    enable = true;
    recommendedProxySettings = true;
    recommendedTlsSettings = true;
    virtualHosts = {
      "outline.example.tld" = {
        onlySSL = true;
        useACMEHost = "example.tld"; # assuming security.acme.certs."example.tld" with `extraDomainNames = [ "outline.example.tld" ]`
        locations."/" = {
          proxyPass = "http://localhost:${toString config.services.outline.port}";
          proxyWebsockets = true;
          extraConfig = ''
                proxy_set_header X-Scheme $scheme;
          '';
        };
      };
      "dex.example.tld" = {
        onlySSL = true;
        useACMEHost = "example.tld";
        locations."/" = {
          proxyPass = "http://${config.services.dex.settings.web.http}";
          proxyWebsockets = true;
        };
      };
    };
  };


  services.outline = {
    enable = true;
    publicUrl = "https://outline.example.tld";
    port = 3003; # using 3003 instead of default 3000 just in case another service is already using 3000
    forceHttps = false;
    storage.storageType = "local";
    oidcAuthentication = {
      authUrl = "https://dex.example.tld/auth";
      tokenUrl = "https://dex.example.tld/token";
      userinfoUrl = "https://dex.example.tld/userinfo";
      clientId = "outline";
      clientSecretFile = (builtins.elemAt config.services.dex.settings.staticClients 0).secretFile;
      scopes = [ "openid" "email" "profile" ];
      usernameClaim = "preferred_username";
      displayName = "Dex";
    };
  };

  services.dex = {
    enable = true;
    settings = {
      issuer = "https://dex.example.tld";
      storage.type = "sqlite3";
      web.http = "127.0.0.1:5556";
      staticClients = [
        {
          id = "outline";
          name = "Outline Client";
          redirectURIs = [ "https://outline.example.tld/auth/oidc.callback" ];
          secretFile = "${pkgs.writeText "outline-oidc-secret" "test123"}";
        }
      ];
      staticPasswords = [
        {
          email = "user.email@example.com";
          # bcrypt hash of the string "password": $(echo password | htpasswd -BinC 10 admin | cut -d: -f2)
          hash = "10$TDh68T5XUK10$TDh68T5XUK10$TDh68T5XUK";
          username = "test";
          # easily generated with `$ uuidgen`
          userID = "6D196B03-8A28-4D6E-B849-9298168CBA34";
        }
      ];
    };
  };

Troubleshooting

Option storageType does not exist

If you see an error that says something like option "services.outline.storage.storageType" does not exist" you may need to update your channels (nix-channel --update)
