How is CGit able to see the repositories?  Unlike Jenkins, CGit does not
speak any of the Git protocols, it expects to see repositories in the
file system.

Are you Docker containers sharing an underlying filesystem, or do you
have some external job that is cloning the repositories for CGit?

Since CGit is a CGI program, you can just run it and see what happens.
You may want to export PATH_INFO=/ before doing so to make sure it
generates the index.

You can run under strace to monitor what is going on during repository
discovery.
