docker-openresty is a Debian based docker image for OpenResty
I saw that openresty has a docker initiative over at their github project page, but what was missing were Debian Images. Here you will find both jessie and wheezy build flavors.
For the automated builds go to hub.docker.com.
You can use these images directly from hub.docker.com by issuing the following docker commands:
docker pull mcroth/docker-openresty:jessie
docker pull mcroth/docker-openresty:wheezy
UPDATE: openresty/docker-openresty added jessie and wheezy official builds. I will leave this here for historical reason. Thanks @neomantra for the mention!
