docker started throwing this error:
standard_init_linux.go:178: exec user process caused "exec format error"
whenever I run a specific docker container with CMD or ENTRYPOINT, with no regard to any changes to the file other then removing CMD or ENTRYPOINT. here is the docker file I have been working with which worked perfectly until about an hour ago:
