## How to use it
- [Install docker](https://docs.docker.com/install/)
- [Install docker-compose](https://docs.docker.com/compose/install/) (be sure that docker-compose version is at least 1.9.0)
- only on MacOSX: ```brew install coreutils``` to install ```greadlink```
- Get searxng-docker:
  ```sh
  cd /usr/local
  git clone https://github.com/searxng/searxng-docker.git
  cd searxng-docker
  ```
- Generate MORTY_KEY ```sed -i "s|ReplaceWithARealKey\!|$(openssl rand -base64 33)|g" .env```
- Edit the other settings in [.env](https://github.com/searxng/searxng-docker/blob/master/.env) file according to your need
- Check everything is working: ```./start.sh```
- ```cp searxng-docker.service.template searxng-docker.service```
- edit the content of ```WorkingDirectory``` in the ```searxng-docker.service``` file (only if the installation path is different from /usr/local/searxng-docker)
- Install the systemd unit:
  ```sh
  systemctl enable $(pwd)/searxng-docker.service
  systemctl start searxng-docker.service
  ```

## Note on the image proxy feature

The SearXNG image proxy is activated by default using [Morty](https://github.com/dalf/morty).

The default [Content-Security-Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy) allow the browser to access to {SEARXNG_HOSTNAME} and ```https://*.tile.openstreetmap.org;```.

If some users wants to disable the image proxy, you have to modify [./Caddyfile](https://github.com/searxng/searxng-docker/blob/master/Caddyfile). Replace the ```img-src 'self' data: https://*.tile.openstreetmap.org;``` by ```img-src * data:;```.

## Custom docker-compose.yaml

Do not modify docker-compose.yaml otherwise you won't be able to update easily from the git repository.

It is possible to use the [extend feature](https://docs.docker.com/compose/extends/) of docker-compose:
- stop the service: ```systemctl stop searxng-docker.service```
- create a new docker-compose-extend.yaml, check with ```start.sh```
- update searxng-docker.service (see SEARXNG_DOCKERCOMPOSEFILE)
- restart the service: ```systemctl restart searxng-docker.service```

## Multi Architecture Docker images

For now only the amd64 platform is supported.

## How to update ?

Check the content of [```update.sh```](https://github.com/searxng/searxng-docker/blob/master/update.sh).

## Access to the Filtron API

The [Filtron API](https://github.com/dalf/filtron#api) is available on ```http://localhost:4041```.

For example, to display the loaded rules:
```
curl http://localhost:4041/rules | jq
```
