What's your ENTRYPOINT? This looks like a bad ENTRYPOINT or CMD definition to the container.

[aaronhurt]

Okay, that's the problem and why you are getting that error message. It's trying to execute all of that as a single binary and can't find it.

Take a look at the CMD and ENTRYPOINT documentation ... specifically the array style. You probably only want to specify ENTRYPOINT or CMD and not both.

https://docs.docker.com/engine/reference/builder/#cmd https://docs.docker.com/engine/reference/builder/#entrypoint

[aaronhurt]

You could do this a few ways:

1) Leave the upstream container ENTRYPOINT and specify CMD

ENTRYPOINT ["/usr/local/bin/consul-backinator"]
CMD ["backup", "-addr=10.0.1.50:8500", "-file=s3://accesskey:secretkey@bakup-consul/consul_backup/?region=us-west-2"]

2) Do not specify an ENTRYPOINT (use the docker default) and specify CMD

CMD ["/usr/local/bin/consul-backinator", "backup", "-addr=10.0.1.50:8500", "-file=s3://accesskey:secretkey@bakup-consul/consul_backup/?region=us-west-2"]

3) Do not modify theDockerfile and pass the arguments at runtime

docker run myena/consul-backinator backup -addr=10.0.1.50:8500 -file=s3://accesskey:secretkey@bakup-consul/consul_backup/?region=us-west-2

This part of the documentation provides a good description:
