OpenResty is a full-fledged web application server by bundling the standard nginx core, lots of 3rd-party nginx modules, as well as most of their external dependencies.
openresty:<version>
You can use the image directly, e.g.
docker run --rm -it chinayin/openresty:1.21
The images are built daily and have the security release enabled, so will contain any security updates released more than 24 hours ago.
You can also use the images as a base for your own Dockerfile:
FROM chinayin/openresty:1.21
