docker: executable file not found in $PATH

Question

I have a docker image which installs grunt, but when I try to run it, I get an error:

Error response from daemon: Cannot start container foo_1         


        

Answer 1

There are several possible reasons for an error like this.

In my case, it was due to the executable file (docker-entrypoint.sh from the Ghost blog Dockerfile) lacking the executable file mode after I'd downloaded it.

Solution: chmod +x docker-entrypoint.sh
