Configuring a reverse proxy
Although the service can be exposed directly to the internet, including handling the TLS termination, many deployments will want to run a reverse proxy in front of the service.
In those configuration, the service should be configured to listen on localhost
or Unix domain socket.
Example configuration
http:
public_base: https://auth.example.com/
listeners:
- name: web
resources:
- name: discovery
- name: human
- name: oauth
- name: compat
- name: graphql
# Uncomment to serve the assets by the service
#- name: assets
# path: ./share/assets/
binds:
# Bind on a local port
- host: localhost
port: 8080
# OR bind on a Unix domain socket
#- socket: /var/run/mas.sock
# OR bind on a systemd socket
#- fd: 0
# kind: tcp # or unix
# Optional: use the PROXY protocol
#proxy_protocol: true
Example nginx configuration
Note that the assets can be served directly by nginx, and the assets
resource can be removed from the service configuration.
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name auth.example.com;
ssl_certificate path/to/fullchain.pem;
ssl_certificate_key path/to/privkey.pem;
location / {
proxy_pass http://localhost:8080;
# OR via the Unix domain socket
#proxy_pass http://unix:/var/run/mas.sock;
proxy_http_version 1.1;
# Optional: use the PROXY protocol
#proxy_protocol on;
}
# Optional: serve the assets directly
location /assets/ {
root /path/to/share/assets/;
# Serve pre-compressed assets
gzip_static on;
# With the ngx_brotli module installed
# https://github.com/google/ngx_brotli
#brotli_static on;
# Cache assets for a year
expires 365d;
}
}
For the compatibility layer, the following endpoints need to be proxied to the service:
/_matrix/client/*/login
/_matrix/client/*/logout
/_matrix/client/*/refresh
For example, a nginx configuration could look like:
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name matrix.example.com;
# Forward to the auth service
location ~ ^/_matrix/client/(.*)/(login|logout|refresh) {
proxy_pass http://localhost:8080;
# OR via the Unix domain socket
#proxy_pass http://unix:/var/run/mas.sock;
proxy_http_version 1.1;
# Optional: use the PROXY protocol
#proxy_protocol on;
}
# Forward to Synapse
# as per https://matrix-org.github.io/synapse/latest/reverse_proxy.html#nginx
location ~ ^(/_matrix|/_synapse/client) {
proxy_pass http://localhost:8008;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $host;
client_max_body_size 50M;
proxy_http_version 1.1;
}
}
