Docker Exec format error

Question

I have dockerfile with: ENTRYPOINT ["/code/docker-entrypoint.sh"]

docker-entrypoint.sh

!/bin/sh
/code/utils/BrowserStackLocal --key xxx  --daemon  start
robot --outputdir ./logs --variable xxx:yyy --variable     ./tests/BasicTestSuite.robot
/code/utils/BrowserStackLocal --key xxx  --daemon  start

When I run image, I am getting error -

  /code/docker-entrypoint.sh: 3: /code/docker-entrypoint.sh:  /code/utils/BrowserStackLocal: Exec format error

But next command (robot --outputdir ...) successfully running.

What Am I doing wrong?

P.S I've done RUN chmod a+x /code/utils/BrowserStackLocal

What is the output of file /code/utils/BrowserStackLocal ? — Aserre

@Aserre Mach-O 64-bit executable x86_64 It seems that I understand what is wrong - this file is only for MacOS, I need download this binary for Linux, yes? — Grzegorzg

Yes. you can download it from here: browserstack.com/local-testing#command-line — mlameiras

Docker will only understand Linux system calls (except for some very specific windows images), so you'll need to provide the correct architecture for the packages you want to add to your containers — Aserre

The file you are executing BrowserStackLocal probably has a different architecture than the Docker image you are running.

Are you by any chance running the 32-bits version in a 64-bit enviornment of BrowserStackLocal? You can check with the command file: file BrowserStackLocal

The other command runs after the first one fails which is expected.
