Creating a linux dockerfile...

ENTRYPOINT ["perl", "ttmp32gme.pl"]

Build it like this:

sudo docker build -t ttmp32gme .

Start it like this:

sudo docker run -p 8081:10020 -it ttmp32gme

A docker image for ttmp32gme sounds great! Would you be willing to share the docker image with other users?

Regarding your questions:
a) building (i.e. creating an executable binary) is indeed not supported for linux. Instead ttmp32gme is meant to be run as a normal perl script. Therefore, you need to change the last two RUN lines to cd ttmp32gme/src && perl ttmp32gme.pl. The buildit.pl script is only meant for building the mac and windows binaries (hence the report of missing Win32/Exe.pm)

You also need to install tttool and ffmpeg within the container and make sure that they are on the PATH (you could try to use the statically linked binaries from the ttmp32gme/lib/mac directory but I never tried them under linux.

Finally, you will need to make sure the container exposes port 10020 to the host.

I updated the installation instructions to be a bit more comprehensive - thanks for providing the incentive ;-)

b) I also had to add the -f options to install some of the perl modules. Most likely the respective modules are simply not maintained well. They did what I needed them to so I did not worry about it...

Let me know if it works or if you need more help.

Hi! I currently have the problem of accessing the service from the outer world. It seems as if the server only allows connections from within localhost - which will not work :-) How do I configure the server to accept connections on all network interfaces?

[thawn]

@anthraxn8b You need to set the host config parameter to 0.0.0.0.
Because you cannot access the web interface within the container, I attach a modified config.sqlite file where that parameter is already changed.
Extract the zip file, rename the config_anyhost.sqlite to config.sqlite and move it to ttmp32gme/src within the container. Within the container remove the ~/.ttmp32gme folder (note the dot at the beginning of the folder name; this is the folder containing the configuration and library) in order to make sure that the modified config is used.
Hope this solves the issue.

[anthraxn8b]

@thawn THX! I replaced the file and the service is reachable (not tested any kind of functionality yet...).
Now I have to install ffmpeg and I will try to use the created executable (by pp) and to minimize the image.

[thawn]

@anthraxn8b if you create an executable with pp, I don't understand why you would need a docker image. pp does something very similar to a docker image: the pp executable contains a perl interpreter and all required perl modules. Therefore, a pp executable should run on any linux system (if you include all necessary binaries and libraries, it would not even need dependencies). Also, creating the pp executable is not so trivial because you need to include several libraries and binaries (check the buildit.pl for how I did that for windows and mac).
Of course it is up to you how you do this but I would recommend to create either a docker image or a pp executable.

1. The docker image could be based on a perl docker image (and thus does not need to include perl itself because docker will dynamically install the perl image as needed) and only include the necessary perl modules, tttool, ffmpeg and the ttmp32gme source files. From the ttmp32gme directory you only need the src subdirectory. you don't need the 'lib' directory, it only contains the tttool and ffmpeg binaries for mac and windows you can also delete the .git directory which should save you >200MB of space. That way, the resulting docker image should be ~50MB.
2. You could include the binary for tttool in the pp executable. That way the executable would only depend on libc6, libxml2, zlib and ffmpeg. In principle, you could even include statically linked versions of these libraries into the executable but these libraries are available on all distros and thus easily installed as dependencies the resulting pp executable would be ~50mB (including all libraries) or ~6mb (without libraries).

Since you seem to be are already there with the docker image, I recommend you go with 1. and simply clean up the docker image :)

We now have a docker image. thanks to @maystar!
