searxng-docker

Create a new SearXNG instance in five minutes using Docker

What is included ?

Name Description Docker image Dockerfile
Caddy Reverse proxy (create a LetsEncrypt certificate automatically) docker.io/library/caddy:2-alpine Dockerfile
SearXNG SearXNG by itself docker.io/searxng/searxng:latest Dockerfile
Valkey In-memory database cgr.dev/chainguard/valkey:latest Valkey-image

How to use it

  • Install docker
  • Get searxng-docker 
    cd /usr/local
git clone https://github.com/searxng/searxng-docker.git
cd searxng-docker
  • Edit the .env file to set the hostname and an email
  • Generate the secret key sed -i "s|ultrasecretkey|$(openssl rand -hex 32)|g" searxng/settings.yml
  • Edit the searxng/settings.yml file according to your need
  • Check everything is working: docker compose up
  • Run SearXNG in the background: docker compose up -d

[!WARNING]
If you use an older version of docker desktop (< 3.6.0), you may have to install Docker Compose v1. Accordingly, you should modify the commands in this documentation to suit Docker Compose v1. For instance, change 'docker compose up' to 'docker-compose up'.

Install the docker-compose plugin (be sure that docker-compose version is at least 1.9.0)

How to access the logs

To access the logs from all the containers use: docker compose logs -f.

To access the logs of one specific container:

  • Caddy: docker compose logs -f caddy
  • SearXNG: docker compose logs -f searxng
  • Valkey: docker compose logs -f redis

Start SearXNG with systemd

You can skip this step if you don't use systemd.

  • 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: 
    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.

The default Content-Security-Policy allow the browser to access to ${SEARXNG_HOSTNAME} and https://*.tile.openstreetmap.org;.

If some users want to disable the image proxy, you have to modify ./Caddyfile. Replace the img-src 'self' data: https://*.tile.openstreetmap.org; by img-src * data:;.

Multi Architecture Docker images

Supported architecture:

  • amd64
  • arm64
  • arm/v7

How to update ?

To update the SearXNG stack:

git pull
docker compose pull
docker compose up -d

Or the old way (with the old docker-compose version):

git pull
docker-compose pull
docker-compose up -d
