If you'd like a different database password, you should also change it in the `docker-compose.yml` **before** your first run.
You'll also need to copy the following to `nginx.conf` in the root of your `lemmy` folder. This will ensure the proxy setup by `docker-compose` will function properly:
```
worker_processes 1;
events {
worker_connections 1024;
}
http {
upstream lemmy {
# this needs to map to the lemmy (server) docker service hostname
server "lemmy:8536";
}
upstream lemmy-ui {
# this needs to map to the lemmy-ui docker service hostname
server "lemmy-ui:1234";
}
server {
# this is the port inside docker, not the public one yet
listen 80;
# change if needed, this is facing the public web
server_name localhost;
server_tokens off;
gzip on;
gzip_types text/css application/javascript image/svg+xml;

add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";

# don't change lemmy-ui or lemmy here, they refer to the upstream definitions on top
set $proxpass "http://lemmy-ui";
if ($http_accept = "application/activity+json") {
set $proxpass "http://lemmy";
}
if ($http_accept = "application/ld+json; profile=\"https://www.w3.org/ns/activitystreams\"") {
set $proxpass "http://lemmy";
}
if ($request_method = POST) {
set $proxpass "http://lemmy";
}
proxy_pass $proxpass;
rewrite ^(.+)/+$ $1 permanent;
# Send actual client IP upstream
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
# backend

# proxy common stuff

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
}
```
After this, have a look at the [config file](configuration.md) named `lemmy.hjson`, and adjust it, in particular the hostname, and possibly the db password. Then run:
`docker-compose up -d`
You can access the lemmy-ui at `http://localhost:80`
To make Lemmy available outside the server, you need to setup a reverse proxy, like Nginx. You can use the following simple proxy:

Note: If you are planning on running your reverse proxy on port 80, you'll need to update the docker-compose.yml file you just downloaded to change the internal proxy's listening port. If you are setting up Let's Encrypt on the same machine, you'll need to do this.

### Let's Encrypt
You should also setup TLS, for example with [Let's Encrypt](https://letsencrypt.org/). [Here's a guide for setting up letsencrypt on Ubuntu](https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04).
For federation to work, it is important that you do not change any headers that form part of the signature. This includes the `Host` header - you may need to refer to the documentation for your proxy server to pass through the `Host` header unmodified.
