Given your context, this typically means you are missing a shared library. With alpine, it's typically glibc since they ship with libmusl. You can check this with:

ldd chasquid-util

I've got several other reasons for this listed in my DC 2018 slidedeck:

Did you run the intended command? (e.g. docker run --rm my_image -it echo hello world will run the command -it)
Is docker trying to run a json string? (any json paring errors will show up as executing the json as a string)
Does the file exist... in the path and inside the container? (can't run stuff from the host inside a container without building it into the image or mounting a volume)
If it is a shell script, check the first line (e.g. #!/bin/bash)
Check for windows linefeeds on linux shell scripts (look for ^M or \r with different editors)
If it is a binary, there is likely a missing library (use ldd to check)
