Docker instructions

This document describes how to use weserv/images with Docker.

Hosted image on GitHub Container Registry

1. Pull and run the ghcr.io/weserv/images container.

   docker run -d -p 8080:80 --shm-size=1gb --name=weserv ghcr.io/weserv/images:5.x

   (this maps TCP port 80 in the container to port 8080 on the Docker host)

2. Visit http://localhost:8080/.

3. Enjoy!

Manual installation

1. Build the container (with a specified nginx version).

   docker build --build-arg NGINX_VERSION=1.27.4 -t weserv/images -f docker/Dockerfile .

2. Run the container (same as above, but using the recently built tag).

   docker run -d -p 8080:80 --shm-size=1gb --name=weserv weserv/images

3. Visit http://localhost:8080/.

4. Enjoy!
