why am i not able to run docker command inside a shell script

I tried with #!/usr/bin/bash and #!/usr/bin/env/sh and #!/usr/bin/env/ bash

docker run -t -i image-id /bin/sh is what i use and use ls and i see that the file is there

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                       PORTS               NAMES
9c970708c1a3        bd24c6bef682        "/bin/sh -c 'sh benc…"   7 minutes ago       Exited (127) 7 minutes ago                       amazing_lovelace

I am able to run both these commands individually and they work

echo "Getting the Container Name"
containerName=$(docker ps -l --format '{{.Names}}' 2>&1)


echo "Transfering the text file"
docker cp $containerName:/benchmark.txt /Users/xxxx/Devlocal/xxxxx/tests/logs/benchmark.txt

when put in a shell script and run i get: ERROR

benchmark.sh: line 13: docker: not found
The command '/bin/sh -c sh benchmark.sh' returned a non-zero code: 127

please help dockerfile

The script that you call inside the container, executes docker commands. This can only work if you have docker installed in your container, which, by the looks of it, it is not.

If your only aim is to have access to the file /benchmarks.txt, you can mount it when you start your container:

docker run -d -v /Users/xxxx/Devlocal/xxxxx/tests/logs/benchmark.txt:/benchmark.txt ...

Note that you have to add RUN touch /benchmark.txt to your Dockerfile.

The reason for that is here
