Reverse-proxy

If you want to access authentik behind a reverse-proxy, use a config like this. It is important that Websocket is enabled, so that Outposts can connect.

map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}

server {
# Server config
listen 80;
server_name sso.domain.tld;

# 301 to SSL
location / {
return 301 https://$host$request_uri;
}
}
server {
# Server config
listen 443 ssl http2;
server_name sso.domain.tld;

# SSL Certs
ssl_certificate /etc/letsencrypt/live/domain.tld/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/domain.tld/privkey.pem;

# Proxy site
location / {
proxy_pass https://<hostname of your authentik server>:9443;
proxy_http_version 1.1;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# This needs to be set inside the location block, very important.
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
}
