JWT Bearer Token authorization with nginx, openresty, and lua-resty-jwt.
An easy way to setup JWT Bearer Token authorization for any API endpoint, reverse proxy service, or location block without having to touch your server-side code.
This example uses the secret, token, and claims from jwt.io:
Server:
docker run --rm \
-it \
-e JWT_SECRET=secret \
-v `pwd`/nginx.conf:/nginx.conf \
-v `pwd`/bearer.lua:/bearer.lua \
-p 8080:8080 \

# apt-get install httpie || brew install httpie

Edit bearer.lua or create new lua scripts to meet your specific needs for each location block.
Restart a container and volume mount in all of the required configuration.
To update or build a custom image edit the Dockerfile and:
docker build -t ubergarm/openresty-nginx-jwt .I originally tried to get auth0/nginx-jwt working, but even the newer forks are not as straight forward as simply using lua-resty-jwt rock directly.

Also Caddy might be faster for a simple project.
