Make sure you've got Docker and `docker-compose` installed, create a directory and create `docker-compose.yml` file inside it like this: ```yml version: '3' services: webp: image: webpsh/webp-server-go # image: ghcr.io/webp-sh/webp_server_go restart: always environment: - MALLOC_ARENA_MAX=1 volumes: - ./path/to/pics:/opt/pics - ./exhaust:/opt/exhaust ports: - 127.0.0.1:3333:3333 ``` Suppose your website and image has the following pattern. | Image Path | Website Path | | ------------------------------------- | ------------------------------------ | | `/var/www/img.webp.sh/path/tsuki.jpg` | `https://img.webp.sh/path/tsuki.jpg` | Then * `./path/to/pics` should be changed to `/var/www/img.webp.sh` * `./exhaust` is cache folder for output images, by default it will be in `exhaust` directory alongside with `docker-compose.yml` file, if you'd like to keep cached images in another folder as , you can change `./exhaust` to `/some/other/path/to/exhaust` Start the container using: ``` docker-compose up -d ``` Now the server should be running on `127.0.0.1:3333`, visiting `http://127.0.0.1:3333/path/tsuki.jpg` will see the optimized version of `/var/www/img.webp.sh/path/tsuki.jpg`, you can now add reverse proxy to make it public, for example, let Nginx to `proxy_pass http://127.0.0.1:3333/;`, and your WebP Server is on-the-fly! You can refer to [Docker | WebP Server Documentation](https://docs.webp.sh/usage/docker/) for more info, such as custom config, AVIF support etc. ## Advanced Usage If you'd like to use with binary, please consult to [Basic Usage | WebP Server Documentation](https://docs.webp.sh/usage/basic-usage/), spoiler alert: you may encounter issues with `glibc` and some dependency libraries. For supervisor or detailed Nginx configuration, please read our documentation at [https://docs.webp.sh/](https://docs.webp.sh/) ## WebP Cloud Services We are currently building a new service called [WebP Cloud Services](https://webp.se/), it now has two services: * [Public Service](https://public.webp.se) * GitHub Avatar/Gravater reverse proxy with WebP optimization, for example, change `https://www.gravatar.com/avatar/09eba3a443a7ea91cf818f6b27607d66` to `https://gravatar.webp.se/avatar/09eba3a443a7ea91cf818f6b27607d66` for rendering will get a smaller version of gravater, making your website faster * Totally free service and currently has a large number of users, this includes, but is not limited to [CNX Software](https://medium.com/amarao/scaleway-arm-servers-50f85c4cefbe),[Indienova](https://indienova.com/en) * [WebP Cloud](https://docs.webp.se/webp-cloud/) * No need to install WebP Server Go, especially suitable for static websites. * Image Conversion: WebP Cloud converts images to WebP format, reducing size while maintaining quality for faster website loading. * Example: Original image URL (https://yyets.dmesg.app/api/user/avatar/Benny) becomes compressed URL (https://vz4w427.webp.ee/api/user/avatar/Benny). * Caching: WebP Cloud automatically caches served images, reducing traffic and bandwidth load on the origin server.
