+httptester
+==========
+
+HTTP Testing endpoint which provides httpbin, nginx, SSL and SNI
+capabilities, for providing a local HTTP endpoint for testing
+
+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 automtically start on launch, and will have to be
+manually started using::
+
+    $ /services.sh
+
+Such as when starting a docker container::
+
+    docker run -ti --rm -p 80:80 -p 443:443 --name httptester ansible/httptester /services.sh
+
+docker build
+^^^^^^^^^^^^
+
+::
+
+    docker build -t ansible/httptester .
+
+packer
+^^^^^^
+
+The packer build will use ``ansible-playbook`` to perform the
+configuration, and will tag the image as ``ansible/httptester``
+
+::
+
+    packer build packer.json
+
+Ansible
+~~~~~~~
+
+::
+
+    ansible-playbook -i hosts -v httptester.yml
+
