## Version 2023/02/05 - Changelog: https://github.com/linuxserver/docker-swag/commits/master/root/defaults/nginx/authentik-server.conf.sample
# Make sure that your authentik container is in the same user defined bridge network and is named authentik-server

# location for authentik auth requests
location /outpost.goauthentik.io {
    include /config/nginx/proxy.conf;
    include /config/nginx/resolver.conf;
    set $upstream_authentik authentik-server;
    proxy_pass http://$upstream_authentik:9000/outpost.goauthentik.io;

    ## Headers
    proxy_set_header X-Forwarded-Host $host; # overwrite header from proxy.conf to not include $server_port
    proxy_set_header Content-Length "";

    ## Basic Proxy Configuration
    proxy_pass_request_body off;
    client_body_buffer_size 128k;

    ## Advanced Proxy Configuration
    send_timeout 5m;
}

# Virtual location for authentik 401 redirects
location @authentik_401_redirect {
    internal;

    ## Set the $target_url variable based on the original request.
    set_escape_uri $target_url $scheme://$http_host$request_uri;

    ## Include the Set-Cookie header if present.
    auth_request_set $set_cookie $upstream_http_set_cookie;
    add_header Set-Cookie $set_cookie;

    ## Set $authentik_backend to route requests to the current domain by default
    set $authentik_backend $http_host;
    ## In order for Webauthn to work with multiple domains authentik must operate on a separate subdomain
    ## To use authentik on a separate subdomain:
    ##  * comment the $authentik_backend line above
    ##  * rename /config/nginx/proxy-confs/authentik.conf.sample to /config/nginx/proxy-confs/authentik.conf
    ##  * make sure that your dns has a cname set for authentik
    ##  * uncomment the $authentik_backend line below and change example.com to your domain
    ##  * restart the swag container
    #set $authentik_backend authentik.example.com;

    return 302 https://$authentik_backend/authentik/?rd=$target_url;
}
