NGINX with SPIFFE support

This version of NGINX Open Source interacts with the SPIFFE Workload API to request and use certificates for mTLS.

Based on configured SPIFFE IDs, it can accept or reject connections.

Building

Building is best done with the included Dockerfile and Makefile:

• make container - builds the compilation container, including depdancies configured in vendor.sh
• make configure - runs the ./configure process for nginx, as specified in build.sh
• make - builds the nginx binary and copies the results to the top level repo directory
• make clean - cleans the nginx build
• make shell - launches a shell in the build container
