docker-centos-nginx

A Dockerfile that produces a CentOS-based Docker image that will run the latest stable Nginx.

It is ideal to be a base image to serve out PHP-FPM or as a Puppet Master load balancer.

The build is based on [internavenue/docker-centos-base][docker-centos-base].

Included packages (and their dependencies)

• Nginx
• H5BP Nginx boilerplate

Image Creation

This example creates the image with the tag internavenue/centos-nginx, but you can change this to use your own username.

$ docker build -t="internavenue/centos-nginx" .

Alternately, you can run the following if you have GNU Make installed...

$ make

You can also specify a custom docker username like so:

$ make DOCKER_USER=internavenue

Container Creation / Running

The Nginx web server is configured to store web root in /srv/www inside the container. You can map the container's /srv/www volume to a volume on the host so the data becomes independant of the running container.

This example uses /srv/docker/lon-dev-web to host the web application, but you can modify this to your needs.

When the container runs, it creates a superuser with a random password. You can set the username and password for the superuser by setting the container's environment variables. This lets you discover the username and password of the superuser from within a linked container or from the output of docker inspect web1.

$ mkdir -p /srv/docker/lon-dev-web
$ docker run -d -name="web1" \
             -p 127.0.0.1:80:80 \
             -v /srv/docker/lon-dev-web:/srv/www \
             -e USER="super" \
             -e PASS="Whatz03v3r" \
             internavenue/nginx

Alternately, you can run the following if you have GNU Make installed...

$ make run

You can also specify a custom port to bind to on the host, a custom web root directory, and the superuser username and password on the host like so:

$ sudo mkdir -p /srv/docker/lon-dev-web
$ make run PORT=127.0.0.1:8080 \
           DATA_DIR=/my/spec/data/dir \
           USER=super \
           PASS=Whatz03v3r
