From a binary I'm selection the following from the right click menu - "running Debug > C++ container image "

and getting the following error.

Error with command: gdb --version
Cannot run program "gdb": Launching failed

However when I run the docker image and run the same command it seems to work just fine.

# gdb --version

I can build the binary against this docker images just fine, but when I try to debug the code in the docker image I don't seem to be able to do that.

Also it looks like gdb expects to bind to port 2345, but I don't see any option telling the docker image to expose 2345 when I look at the Debug Configuration.

Anyone have any idea as to what's going wrong here?
