docker-ssl-proxy

Builds a basic nginx server that proxies incoming SSL calls to a target host (usually another Docker container). This repository adds proxying a backend directory.

Environment variables

The following environment variables configure nginx:

• SERVER_NAME: name of the server (default value: www.example.com)
• TARGET_SCHEME: target scheme for the reverse proxy (default value: http)
• TARGET_PORT: target port for the reverse proxy (default value: 80)
• TARGET_HOST: target host for the reverse proxy (default value: proxyapp)
• TARGET_HOST_HEADER: value to be used as the Host header when sending requests to the target host (defaults to the value of $TARGET_HOST)
• CLIENT_MAX_BODY_SIZE: maximum size of client uploads (default value: 20M)
• SSL_PORT: port ngnix SSL proxy listens on
• API_SCHEME: target scheme for the backend reverse proxy (default value: http)
• API_PORT: target port for the backend reverse proxy (default value: 3001)
• API_HOST: target host for the backend reverse proxy (default value: proxyapi)
• API_HOST_HEADER: value to be used as the Host header when sending requests to the target host (defaults to the value of $API_HOST)

Using own Certificate

You have to use certificates, otherwise the build will fail. Do so by connecting an volume onto /etc/nginx/certs with following files inside:

• key.pem: private key file
• cert.pem: certificate file

Logging

The container is set to log to /var/log/nginx. You can mount a volume to analyze the logs.
