Running `docker run` from bash script fails. Command does not fail on Command Line

If I run the following from the command line.

docker run -t repo:tag ls -l

the command succeeds just fine. However, if I invoke the same from within a bash script I get the following ERROR:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"ls -l\": executable file not found in $PATH": unknown.

What about the bash script causes this error?

"exec: \"ls -l\": executable file not found in $PATH"

From the error I can tell that when you invoke docker, you somehow invoke with ls -l including space as one argument. Something like, 

docker run -t repo:tag "ls -l" # wrong

or perhaps

cmd="ls -l" 
docker run -t repo:tag "$cmd" # wrong

The shell to parse the docker command must see ls and -l as separate parameters so that the argument -l is distinguished from the ls executable name.

cmd="ls -l" 
docker run -t repo:tag $cmd #works
