Glad you got it working without much documentation needed.
It's still only available in the develop branch. But I think I will take it over soon to the main branch to get feedback.
I just wrote a first version of the documentation:
https://opensource.hcltechsw.com/domino-container/safelinx/
Sadly the requirements for certificates has become more strict. The container comes with it's own root CA.
But today a private CA isn't that helpful. The out of the box CA is just a starting point and you really need a public cert.
There are multiple ways to get it working with multiple integration options. The certificate part is always the hardest part.
There is a NGINX integration as well, that could help in more complex environments in the same sample/safelinx directory.
It comes with documentation in the NGINX file itself.
