Cannot get SSL to work in Docker container

Question

Let me start off by saying that I am no server administrator and there are a great many things I do not know. Because of this I am sure that I have made a mistake somewhere setting up my Docker container, because SSL does not work.

The container is running Apache 2.4 with PHP 5.6 on Ubuntu 14.04 and is linked to a MySQL 5.6 Docker container.

I started with this basic setup from Docker - Official PHP Repo. Here are the relevant files:

RUN apt-get install -y net-tools

NOTE: I have removed non-relevant parts of these files.

To run the Docker container I use this:

sudo docker run -v /home/src/ssl-cert:/etc/ssl/certs --name app-gateway --link mysql56:mysql -p 80:80 -p 443:443 -d  app-image

Here is a section of the log files:

::1 - - [10/Nov/2015:19:26:19 +0000] "OPTIONS * HTTP/1.0" 200 152 "-" "Apache/2.4.10 (Debian) PHP/5.6.15 OpenSSL/1.0.1k (internal dummy connection)"

With this error in the browser:

ERR_SSL_PROTOCOL_ERROR

TL;DR I have followed all of the steps that I have found online to install and use my SSL certificates in a Docker container but I have had no success in making it work. Is there anything obvious I've overlooked to make SSL work in a Docker container?

Solution

Sometimes, especially when you have been trying to solve a problem for a long time and you're coding in a console window on the command line, you miss the simplest things. Have a look at these two lines in the Dockerfile:

ADD 000-default.conf /etc/apache2/sites-enabled/
ADD default-ssl.conf /etc/apache2/sites-anabled/

The a is nearly indistinguishable from an e, making the misspelling hard to find. The Dockerfile builds the image correctly and adds the new directory in the container, then places the configuration file within that directory.

drwxr-xr-x  2 www www  4096 Nov 11 15:56 sites-anabled
drwxr-xr-x  2 www www  4096 Oct 23 20:19 sites-available
drwxr-xr-x  2 www www  4096 Nov 11 15:56 sites-enabled

Since no error is thrown for an unknown directory and the image builds successfully it will run, but in this case the SSL will not work appropriately.
