docker exec command not executing in sh file

Question

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, Apr 02 '15 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. – mainframer Jan 03 '16 at 03:46

There are few images which do not support the interactive shell/bash. Example - Docker image mockserver/mockserver Docker Set Up
