-Building
-========
-
-Docker
-------
-
-Both ways of building ``docker`` utilize the ``nginx:alpine`` image, but can
-be customized for ``Fedora``, ``Red Hat``, ``CentOS``, ``Ubuntu``,
-``Debian`` and other variants of ``Alpine``
-
-When utilizing ``packer`` or configuring with ``ansible-playbook``,
-the services will not automatically start on launch, and will have to be
-manually started using::
-
-    cd test/utils/docker/httptester
-    ./services.sh
-
-Such as when starting a docker container::
-
-    cd test/utils/docker/httptester
-    docker run -ti --rm -p 80:80 -p 443:443 --name httptester ansible/ansible:httptester /services.sh
-
-docker build
-------------
-
-::
-
-    cd test/utils/docker/httptester
-    docker build -t ansible/ansible:httptester .
-
-packer
-------
-
-The ``packer`` build will use ``ansible-playbook`` to perform the
-configuration, and will tag the image as ``ansible/ansible:httptester``::
-
-    cd test/utils/docker/httptester
-    packer build packer.json
-
-Ansible
-=======
-
-::
-    cd test/utils/docker/httptester
-    ansible-playbook -i hosts -v httptester.yml
