Unable to run script.sh inside docker agent

[tomdottom]

When trying to run the following declarative pipeline:

pipeline {
    agent { docker 'alpine' }
    stages {
        stage('Test') {
            steps {
                sh('printenv')
            }
        }
    }
}

I get the error:

When monitoring the pipelines @tmp directory whilst its running I can see script.sh created.

some system details

Same here, some fix?
My config:

• Jenkins 2.60.2
• Docker version 17.03.1-ce, build c6d412e

@tomdottom The docker image must have inside the jenkins agent ready for run. In my case, a workaround is use a custom Dockerfile with base of https://hub.docker.com/r/jenkinsci/slave/~/dockerfile/ and adding the things I need (docker for example).
Once you have a jenkins agent running inside the container, the sh will exec correctly.

@AndresCidoncha thanks for the suggested solution.

@tomdottom do you have '/bin/bash' as Shell executable command on Jenkins->Configure System page? In this case '/bin/sh' should fix it.

I had the same problem, and it was caused because the format of the bash script was incorrect.
I noticed it when I tried to run my script on my local computer and I saw the error message:

/bin/sh^M: bad interpreter: No such file or directory.

After to fix this issue my script was executed successfully.
