Deployment¶

This page details what to install on your server to make a production-ready environment for Canaille.

Application service¶

After having finished Canaille installation you have to run it in a WSGI application server. Several application servers are available, like Gunicorn, uWSGI, uvicorn or Hypercorn for example.

Canaille comes with a light Hypercorn integration but you can use it with any application server. The WSGI entry-point to configure in your server of choice is canaille:create_app.

Hypercorn integration¶

To run the integrated Hypercorn application server, you can simply run the canaille run command. The hypercorn integration is embedded in the Canaille binaries. However if you use the Canaille Python package, you will need the [server] extra (for instance with pip install canaille[server] for Hypercorn to be available.

Running the Canaille run command¶

$ canaille run
[2025-01-02 16:39:18 +0100] [304043] [INFO] Running on http://127.0.0.1:8000 (CTRL + C to quit)
[2025-01-02 16:39:18,412] INFO in logging: Running on http://127.0.0.1:8000 (CTRL + C to quit)

By default it runs on the port 8000 of localhost, this could be enough but you might want to customize it a little bit more. Fortunately Hypercorn provides a configuration documentation to adjust it to your needs. You can write a TOML Hypercorn configuration file and pass it in parameter.

Running the Canaille run command with a configuration file¶

$ canaille run --config hypercorn.toml

Here is a basic Hypercorn configuration file that you can tune:

Hypercorn toml configuration example¶

workers = 4
bind = "unix:/run/canaille.sock"
umask = "007"
logfile = "/var/log/hypercorn/canaille.log"
loglevel = "info"

Webserver¶

Now you have to plug your WSGI application server to your webserver so it is accessible on the internet. Here are some webserver configuration examples you can pick:

Nginx¶

Nginx configuration example for Canaille¶

server {
    listen 80;
    listen [::]:80;
    server_name auth.mydomain.example;
    return 301 https://$server_name$request_uri;

Apache¶

Apache configuration example for Canaille¶

<VirtualHost *:80>
    ServerName auth.mydomain.example
    ServerAdmin admin@mydomain.example

    CustomLog /opt/canaille/logs/apache-http-access.log combined
    ErrorLog /opt/canaille/logs/apache-http-error.log

    RewriteEngine On
    RewriteCond %{REQUEST_URI} !^/\.well\-known/acme\-challenge/
    RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,L]    </VirtualHost>
</VirtualHost>

<VirtualHost *:443>
    ServerName auth.mydomain.example
    ServerAdmin admin@mydomain.example
    Protocols h2 http/1.1

    CustomLog /opt/canaille/logs/apache-https-access.log combined
    ErrorLog /opt/canaille/logs/apache-https-error.log

    SSLEngine On
    SSLCertificateFile      /etc/letsencrypt/live/auth.mydomain.example/fullchain.pem
    SSLCertificateKeyFile   /etc/letsencrypt/live/auth.mydomain.example/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf

    ProxyPreserveHost On
    ProxyPass /static/ !
    ProxyPass / unix:/run/canaille.sock
    ProxyPassReverse / unix:/run/canaille.sock

    RequestHeader set X-FORWARDED-PROTOCOL ssl
    RequestHeader set X-FORWARDED-SSL on
</VirtualHost>

Recurrent jobs¶

You might want to clean up your database to avoid it growing too much. You can regularly delete expired tokens and authorization codes with:

env CONFIG="$CANAILLE_CONF_DIR/config.toml" FLASK_APP=canaille "$CANAILLE_INSTALL_DIR/env/bin/canaille" clean

Webfinger¶

You may want to configure a WebFinger endpoint on your main website to allow the automatic discovery of your Canaille installation based on the account name of one of your users. For instance, suppose your domain is mydomain.example and your Canaille domain is auth.mydomain.example and there is a user john.doe. A third-party application could require to authenticate the user and ask them for a user account. The user would give their account john.doe@mydomain.example, then the application would perform a WebFinger request at https://mydomain.example/.well-known/webfinger and the response would contain the address of the authentication server https://auth.mydomain.example. With this information the third party application can redirect the user to the Canaille authentication page.

The difficulty here is that the WebFinger endpoint must be hosted at the top-level domain (i.e. mydomain.example) while the authentication server might be hosted on a sublevel (i.e. auth.mydomain.example). Canaille provides a WebFinger endpoint, but if it is not hosted at the top-level domain, a web redirection is required on the /.well-known/webfinger path.

Here are configuration examples for Nginx or Apache:

Nginx webfinger configuration for a top level domain¶

 server {
     listen 443;
     server_name mydomain.example;
     rewrite  ^/.well-known/webfinger https://auth.mydomain.example/.well-known/webfinger permanent;
 }

Apache webfinger configuration for a top level domain¶

 <VirtualHost *:443>
     ServerName mydomain.example
     RewriteEngine on
     RewriteRule "^/.well-know/webfinger" "https://auth.mydomain.example/.well-known/webfinger" [R,L]
 </VirtualHost>
