# Installing Baserow behind Nginx
If you have an [Nginx server](https://www.nginx.com/) this guide will explain how to
configure it to pass requests through to Baserow.
We strongly recommend you use our `baserow/baserow:1.24.2` image or the example
`docker-compose.yml` files (excluding the `.no-caddy.yml` variant) provided in
our [git repository](https://gitlab.com/baserow/baserow/-/tree/master/deploy/nginx/).
These come with a pre-configured, simple and lightweight Caddy http server which
simplifies your life by:
1. Routing requests to the correct internal Baserow services
2. Enabling websocket connections for realtime collaboration
3. Serving user uploaded files
4. **And it still runs behind your own reverse proxy with no problems**
> If you do not want to use our embedded Caddy service behind your Nginx then
> make sure you are using one of the two following deployment methods:
>
> * Your own container setup with our single service `baserow/backend:1.24.2`
and `baserow/web-frontend:1.24.2` images.
> * Or our `docker-compose.no-caddy.yml` example file in our [git repository](https://gitlab.com/baserow/baserow/-/tree/master/deploy/nginx/).
>
> Then you should use **Option 2: Without our embedded Caddy** section instead.
## Option 1: With our embedded Caddy
> You can find a Dockerized working example of using Nginx with Baserow in our git repo in
> the [deploy/nginx/recommended](https://gitlab.com/baserow/baserow/-/tree/master/deploy/nginx/)
> folder.
Follow this option if you are using:
* The all-in-one Baserow image `baserow/baserow:1.24.2`
* Any of the example compose files found in the root of our git
repository `docker-compose.yml`/`docker-compose.local-build.yml`
/`docker-compose.all-in-one.yml`
### Prerequisites
We assume you already have a Nginx server running which you know how to configure.
Additionally, we assume you are using a debian based operating system and have already
successfully deployed Baserow.
### Step 1 - Configure Baserow's BASEROW_PUBLIC_URL
Baserow needs to know the URL it will be accessed on. We'll assume you will be hosting
Baserow on a subdomain and so you should set the following environment variable on your
Baserow deployment (see [Configuring Baserow](./configuration.md) for more details).
```
BASEROW_PUBLIC_URL=http://baserow.example.com
```
### Step 2 - Add nginx config for Baserow
Create a new `baserow.conf` in `/etc/nginx/sites-available/` with the following contents:
> Make sure to replace any http://localhost:PORT references with the correct ones for
> your particular Baserow deployment.
```
server {
server_name baserow.example.com;
# Upgrade websocket requests and route the api backend
location ~ ^/(api|ws)/ {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://localhost:8080;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_pass http://localhost:8080;
}
}
```
### Step 3 - Enable the new Baserow site
Finally, you should enable your new Baserow site and restart your Baserow server if you
made environment variable changes.
```bash
sudo ln -s /etc/nginx/sites-available/baserow.conf /etc/nginx/sites-enabled/baserow.conf
sudo systemctl reload nginx
```
You should now be able to access Baserow on you configured subdomain.
## Option 2: Without our embedded Caddy
> You can find a Dockerized working example of using Nginx with Baserow in our git repo in
> the [deploy/nginx/no-caddy](https://gitlab.com/baserow/baserow/-/tree/master/deploy/nginx/)
> folder.
Follow this option if you are using:
* Our standalone `baserow/backend:1.24.2` and `baserow/web-frontend:1.24.2` images with
your own container orchestrator.
* Or the `docker-compose.no-caddy.yml` example docker compose file in the root of our
git repository.
### Prerequisites
We assume you already have a Nginx server running which you know how to configure.
Additionally, we assume you are using a debian based operating system and have already
successfully deployed Baserow. If you are using a different setup the
general steps and Nginx config should still be a useful starting point for you,
but you might have to run different commands.
### Step 1 - Mount the media volume so Nginx can serve uploaded files
You need to ensure user uploaded files are accessible in a folder for Nginx to serve. In
the rest of the guide we will use the example `/var/web` folder for this purpose.
If you are using the `baserow/backend:1.24.2` image then you can do this by adding
`-v /var/web:/baserow/data/media` to your normal `docker run` command used to launch the
Baserow backend.
If you are instead using the `docker-compose.no-caddy.yml` then you can change all of
the
`- media:/baserow/media` mounts to be `- /var/web:/baserow/media`.
### Step 2 - Configure Baserow's BASEROW_PUBLIC_URL
Baserow needs to know the URL it will be accessed on. We'll assume you will be hosting
Baserow on a subdomain and so you should set the following environment variable on your
Baserow deployment (see [Configuring Baserow](./configuration.md) for more details).
```
BASEROW_PUBLIC_URL=http://baserow.example.com
```
### Step 3 - Add nginx config for Baserow
Create a new `baserow.conf` in `/etc/nginx/sites-enabled/` with the following contents:
> Make sure to replace any http://localhost:PORT references with the correct ones for
> your particular Baserow deployment.
```
server {
server_name baserow.example.com;
# Upgrade websocket requests and route the api backend
location ~ ^/(api|ws)/ {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://localhost:8000;
}
location /media/ {
if ($arg_dl) {
add_header Content-disposition "attachment; filename=$arg_dl";
}
# TODO Change to your media folder location!
alias /var/www/;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_pass http://localhost:3000;
}
}
```
### Step 4 - Enable the new Baserow site
Finally, you should enable your new Baserow site and restart your Baserow server if you
made environment variable changes.
```bash
sudo ln -s /etc/nginx/sites-available/baserow.conf /etc/nginx/sites-enabled/baserow.conf
sudo systemctl reload nginx
```
You should now be able to access Baserow on you configured subdomain.
### Troubleshooting
If you can upload images to Baserow but no thumbnails show, or you can't re-download
them (you are getting 403 denied errors when accessing the files) then:
* Make sure the permissions on the sub-folders in /var/web are set to be readable by
your Nginx user by running `cd /var/web && chmod 755 *`.
* Fix any file permissions found inside the `/var/web` sub-folders to be readable by
your Nginx user.
