Nginx 1.12 server and a reverse proxy server container image

This container image includes Nginx 1.12 server and a reverse server for OpenShift and general usage. Users can choose RHEL based image. The RHEL image is available in the Red Hat Container Catalog as


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 1.12 daemon. The image can be used as a base image for other applications based on nginx 1.12 web server. Nginx server image can be extended using source-to-image tool.


To build a simple sample-app application using standalone S2I and then run the resulting image with Docker execute:

  • For RHEL based image $ s2i build --context-dir=1.12/test/test-app/ rhscl/nginx-112-rhel7 nginx-sample-app $ docker run -p 8080:8080 nginx-sample-app

  • For CentOS based image $ s2i build --context-dir=1.12/test/test-app/ centos/nginx-112-centos7 nginx-sample-app $ docker run -p 8080:8080 nginx-sample-app

Accessing the application:

$ curl

S2I build support

Nginx server image can be extended using S2I tool (see Usage section). S2I build folder structure:

./nginx.conf-- The main nginx configuration file

Should contain all nginx configuration we want to include into image

Contains any nginx config snippets to include in the default server block

Contains shell scripts that are sourced right before nginx is launched

Should contain nginx application source code

Environment variables and volumes

The nginx container image supports the following configuration variable, which can be set by using the -e option with the docker run command:

When NGINX_LOG_TO_VOLUME is set, nginx logs into /var/opt/rh/rh-nginx112/log/nginx/

You can mount your own web root like this:

$ docker run -v <DIR>:/var/www/html/ <container>

You can replace \<DIR> with location of your web root. Please note that this has to be an absolute path, due to Docker requirements.


By default, nginx logs into standard output, so the log is available in the container log. The log can be examined by running:

docker logs <container>

If NGINX_LOG_TO_VOLUME variable is set, nginx logs into /var/opt/rh/rh-nginx112/log/nginx/, which can be mounted to host system using the container volumes.
