Dockerfile: command not found

What the docker image should run:

-bash-4.2$ pwd
/u/workspaces/compose/src

-bash-4.2$ ls
compileAndTest 

-bash-4.2$ vim compileAndTest
#!/usr/bin/env bash

echo 'hi'

Dockerfile

-bash-4.2$ pwd
/u/mybuild

-bash-4.2$ ls
Dockerfile

-bash-4.2$ vim Dockerfile
FROM java
WORKDIR /u/workspaces/compose
CMD /src/compileAndTest

build and run

-bash-4.2$ docker build -t myjavabuild .

-bash-4.2$ docker run myjavabuild
/bin/sh: 1: /src/compileAndTest: not found

even though the path to the executable compileAndTest is specified in Dockerfile, it says not found

anyone know why?

Add compileAndTest file from host machine is missing.

The problem here is that you are not copying the /src/compileAndTest file to the filesystem of the container. You could use the ADD tag in the Dockerfile to achieve that. 

FROM java
WORKDIR /u/workspaces/compose
ADD /u/workspaces/compose/src/compileAndTest /src/compileAndTest
RUN chmod +x /src/compileAndTest
CMD /src/compileAndTest
