nginx-ssl-proxy

Nginx reverse proxy for SSL termination inside Kubernetes clusters with Let's Encrypt certificates.

Usage

Available on Docker Hub as pavlov/nginx-ssl-proxy. Designed to work with ployst/letsencrypt.

The nginx instance acts as a reverse proxy, providing SSL termination for other services in the cluster. SSL certificates, keys, and other secrets are managed via Kubernetes secrets.

Generating test certificates

THIS IS NOT FOR PRODUCTION USE.

Use the setup-certs.sh script to generate test certificates. It will create your own Certificate Authority and use that to self sign a certificate.

./setup-certs.sh /path/to/certs/folder

Development

$ make build
$ make push
