I don't suppose anyone knows how to override a Docker container's standard behavior and make it boot into Bash rather than the process it's designed to startup as? (I have a malfunctioning container that starts up, errors out, and shuts down again too quickly for me to connect to it in Bash and poke around to figure out the problem.)

how are you running the container?

just from the cmd line?

yeah, just basic

docker run blah blah blah

something like

docker run -it --entrypoint /bin/bash blah blah blah
