When running below command in command line(terminal) this gets executed fine:
$sudo docker exec -it 5570dc09b58 bash
But same results with :
FATA[0000] cannot enable tty mode on non tty input
Error when running in a shell script file.

Well, that makes sense; there is no terminal in a shell script. What are trying to do?Adrian Mouat– Adrian Mouat2015-04-02 10:59:16 +00:00Commented Apr 2, 2015 at 10:59

Scripts may be forced to run in interactive mode with the -i option or with a #!/bin/bash -i header.
So adding shebang to the script with -i option should work:
#!/bin/bash -i
docker exec -it ed3d9e46b8ee date
Run the script as usual:
chmod +x run.sh
sudo ./run.sh
Output:

You are not running docker in a terminal, so you should remove -t from -it:
sudo docker exec -i 5570dc09b58 bash

This is the correct answer. I was using
-it in jenkins Execute Shell but met this error. After I remove the -t, it works, thanks.There are few images which do not support the interactive shell/bash. Example - Docker image mockserver/mockserver Docker Set Up
