This has not so much to do with docker as with the system it is running on. If you take a look in this table of reserved exit codes for bash, you can see the line:
128+n Fatal error signal "n" kill -9 $PPID of script $? returns 137 (128 + 9)
Which corresponds to the 137 you mention. It is 128 + 9 (SIGKILL), which you can see in the signal(7) man page. Normally a 0 means a clean exit and 1 there was something wrong, these two can suffice for a programmer. They can however range from 1-255, including the reserved ones mentioned above.
This is just a short answer as I am not an expert on the subject, you can find more on this unix.stackexchange thread on default exit code when process is terminated or perhaps someone here can give a much more elaborate answer than mine.
