Introduction

Dockerfile to create a Docker container image for NGINX with ngx_pagespeed and nginx-rtmp-module module support.

NGINX is a web server with a strong focus on high concurrency, performance and low memory usage. It can also act as a reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer and an HTTP cache.

Issues

If you are using SELinux, please check out this policy

Before reporting your issue please try updating Docker to the latest version and check if it resolves the issue. Refer to the Docker installation guide for instructions.

SELinux users should try disabling SELinux using the command setenforce 0 to see if it resolves the issue.

If the above recommendations do not help then report your issue along with the following information:

• Output of the docker version and docker info commands
• The docker run command or docker-compose.yml used to start the image. Mask out the sensitive bits.
• Please state if you are using Boot2Docker, VirtualBox, etc.

Getting started

Installation

Automated builds of the image are available on Dockerhub and is the recommended method of installation.

Note: Builds are also available on Quay.io

docker pull sameersbn/nginx:1.10.3

Alternatively you can build the image yourself.

docker build -t sameersbn/nginx github.com/sameersbn/docker-nginx

Quickstart

Start NGINX using:

docker run --name nginx -d --restart=always \
  --publish 80:80 \
  sameersbn/nginx:1.10.3

Alternatively, you can use the sample docker-compose.yml file to start the container using Docker Compose

Command-line arguments

You can customize the launch command of NGINX server by specifying arguments to nginx on the docker run command. For example the following command prints the help menu of nginx command:

docker run --name nginx -it --rm \
  --publish 80:80 \
  sameersbn/nginx:1.10.3 -h

Configuration

To configure NGINX as per your requirements edit the default nginx.conf and mount it at /etc/nginx/nginx.conf.

docker run --name nginx -it --rm \
  --publish 80:80 \
  --volume /srv/docker/nginx/nginx.conf:/etc/nginx/nginx.conf \
  sameersbn/nginx:1.10.3

To configure virtual hosts, mount the directory containing the virtual host configurations at /etc/nginx/sites-enabled/.

docker run --name nginx -it --rm \
  --publish 80:80 \
  --volume /srv/docker/nginx/nginx.conf:/etc/nginx/nginx.conf \
  --volume /srv/docker/nginx/sites-enabled:/etc/nginx/sites-enabled \
  sameersbn/nginx:1.10.3

Note: SELinux users should update the security context of the host mountpoints so that it plays nicely with Docker:

mkdir -p /srv/docker/nginx
chcon -Rt svirt_sandbox_file_t /srv/docker/nginx

To reload the NGINX configuration on a running instance you can send the HUP signal to the container.

docker kill -s HUP nginx

Logs

To access the NGINX logs, located at /var/log/nginx, you can use docker exec. For example, if you want to tail the logs:

docker exec -it nginx tail -f /var/log/nginx/access.log

Maintenance

Upgrading

To upgrade to newer releases:

1. Download the updated Docker image:

docker pull sameersbn/nginx:1.10.3

2. Stop the currently running image:

docker stop nginx

3. Remove the stopped container

docker rm -v nginx

4. Start the updated image

docker run -name nginx -d \
  [OPTIONS] \
  sameersbn/nginx:1.10.3

Shell Access

For debugging and maintenance purposes you may want access the containers shell. If you are using Docker version 1.3.0 or higher you can access a running containers shell by starting bash using docker exec:

docker exec -it nginx bash
