ENV SUMMARY="Platform for running nginx $NGINX_VERSION or building nginx-based application" \
    DESCRIPTION="Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and IMAP \
protocols, with a strong focus on high concurrency, performance and low memory usage. The container \
image provides a containerized packaging of the nginx $NGINX_VERSION daemon. The image can be used \
as a base image for other applications based on nginx $NGINX_VERSION web server. \
Nginx server image can be extended using source-to-image tool."
