Hi,

Not sure that this helps, but below is how I solved similar issue by generating include file inside Docker file using env variables, but this is not a good approach for sensitive data.

echo "\
modparam(\"http_client\", \"httpcon\", \"apiserver=>https://$apiurl\"); \
" >> /kamailio.apiurl

I believe you can use docker secrets, as described below, but I never used them so I can't help much:

With kind regards,

My guess is the next problem will be the password being visible to all
users querying the processlist :)

Is including a file (import_file) with passwords an option? Generate the
file just before startup, remove it (ofcourse in a secure way (shred the
file and overwrite all freespace with a multiple patters a few dozen
times (ask the auditors for the exact specifications that make them
happy))) after kamailio is running.
