Unable to clone private repo within docker container: unable to find any valid known_hosts file, set SSH_KNOWN_HOSTS env variable

[manuel-koch]

Since installing labours failed ( installing scipy stuff ) on my platform (MacOS 12.6.3 M1) I tried to use the docker image to run hercules.
I want to analyze a private repo on bitbucket, hence I need to provide my SSH key to hercules.
Somehow the clone of the repo fails:

( redacted private information regarding the repo )

$ docker run -v ~/.ssh/id_rsa:/key/id_rsa  --rm srcd/hercules hercules --burndown --pb --ssh-identity /key/id_rsa git@bitbucket.org:<MY_PRIVATE_REPO>.git

How can I use hercules to analyze a private repo ?

$ docker image ls | grep hercules
srcd/hercules                                                       latest    5c0c71aebf8c   2 years ago     1.23GB

Found a similar ticket that mentions an updated go-git package that fixes the problem. Maybe the docker image is way out-of-date ( looks like 2 years old ) and may not include the latest hercules build.

Tried to build the docker image manually using the provided Dockerfile, but that seems to be outdated too, causing various python install problems during docker build.
