It is the Factor VM (~tools.giftbot-factor/factor/factor; https://factorcode.org). When I try to run it with the image (or any other image as far as I remember) and use SSL, the following error message appears:
tools.giftbot-factor@tools-sgebastion-10:~$ cat tests.* Cannot resolve C library function Library: DLL" libcrypto.so" Symbol: BIO_new_socket DlError: none See http://concatenative.org/wiki/view/Factor/Requirements (stacktrace)
Are you still working on custom images? If you are, I would just wait until I can use them.
With the clarifications from T304983#8319645 I am going to decline this ticket.
T194332: [Epic] Make Toolforge a proper platform as a service with push-to-deploy and build packs is one way that it may be possible in the future for a custom complied runtime like factor to be made available for tools running on Kubernetes. It may also currently be possible to find a Kubernetes container that has the parts needed to compile and run the factor runtime. The python images for example contain a number of 'lib*-dev' packages to support compiling various binary extensions.
