mitmproxy/mitmproxy:latest Docker image: env: can't execute 'bash': No such file or directory

Problem Description

I was using mitmproxy/mitmproxy:latest Docker image as a base for my custom image. In my image entrypoint script uses tiny shell script to set up certificates from the environment variable. Today I noticed that my container doesn’t start and crashes with the following error:

env: can't execute 'bash': No such file or directory

My shell script:

#! /usr/bin/env sh

PEM=$SERVER_PEM

if [ -z "$PEM" ]; then
    echo "Server PEM is not set"
    exit 1
fi

echo "$PEM" > ./server.pem

echo "Server PEM is set"

With mitmproxy/mitmproxy:5.0.1 image everything is fine.

Steps to reproduce the behavior:

docker run -it --rm mitmproxy/mitmproxy:latest sh

System Information

mitmproxy/mitmproxy:latest Docker image Docker Desktop 2.2.0.5 on macOS Catalina 10.15.3

Confirming, both latest and dev tags work as expected.

Thanks, I will try a little later today!

@MagnificentUrukHai https://github.com/MagnificentUrukHai please try with the most recent dev tag of the Docker image - it should fix the problem. I plan to release a proper bugfix release later today.
