Ah, the problem looks like /home/tech is missing
415 chdir("/home/tech") = -1 ENOENT (No such file or directory)
Really Dropbear should just print a warning there.

It looks like the tech user shell is just exiting early for some reason. If you can have strace in the container, could you log in as root, "strace -f -o log1.txt -p dropbearserverpid", log in as tech, then see if any files are missing etc?
Might also be worth putting some debug logging in ~tech/.bashrc (or whichever shell)
from dropbear.

I'm not sure what you meant by putting debug logging in my bashrc, but I did get some logs from strace. There's two files because in the container there were two PIDs (maybe because the docker daemon is started in a script instead of directly from the dockerfile). Here's the output from one process:
