I have a running container, and I wish to save it as an image, specifying a startup script (bash script) when it is launched.

Inside the container, before saving to image, I have created a file:

  /home/data/bin/run.sh

The first line in /home/data/bin/run.sh is:   

#!/bin/bash

I save the image with this command:

$podman commit --change "CMD=/home/data/bin/run.sh" <container_id> <img_name>

Then I try to run the image, instantiating a container, and I get an error:

/bin/sh: /bin/sh: cannot execute binary file

I don't understand why it is using /bin/sh.  At the very top of my run.sh I have:  #!/bin/bash

---

I tried something slightly different, saving the image using the following command, and I get the same error message:

$podman commit --change "CMD=/bin/bash /home/data/bin/run.sh" $ID $NAME

Any ideas would be greatly appreciated, thank you.

I think the entrypoint is the issue.

You could try setting this as the entrypoint rather then the command.
