Crash on Startup

[skysteve]

I assume this is a lack of understanding from my end however I can't work out what I'm not doing/doing wrong.

I built and ran a container without any attached volume, that worked fine and if I hit http://mitm.it/ I get the install cert page which is fine.

I then tried attaching a volume without anything in. This created some certificates and then crashes. The stack trace is below with a screenshot of what was created and my docker-compose file.

I've also tried this with having common.conf mitmdump.conf and mitmproxy.conf files in the attached volume but that doesn't seem to make things better.

Any help would be much appreciated (This might be a bug in mitmproxy itself, my knowledge of mitmproxy is currently rather limited).

Cheers Steve

Thanks for the report! This looks like a duplicate of mitmproxy/mitmproxy#1157?

[skysteve]

Thanks :) don't think that's 100% related but did help me figure out what was wrong.

If I set tty: true in the docker-compose file everything seems to work. I'll close this
