Description

Container image is built and executed correctly but step commands run outside container.

Jenkins 2.121.1 (running as a systemd unit on master and a remote build node through SSH Slave plugin)

Docker Pipeline plugin 1.17 (released in May 2018)

Docker CE 18.03 running on CentOS 7.5

 

```
pipeline {
agent { dockerfile true }
stages {
stage('Test') {
steps {
sh 'cd /app && npm test'
}
}
}
}
```

And then the test stage doesn't run inside the Docker container that was started:

```

Running the Docker image that Jenkins built works just fine:

```
$ docker run --rm -ti 1d0c4aca5306042f527e42c2e15dd885f78a0ac3 /bin/sh

Raw content of original issue

Container image is built and executed correctly but step commands run outside container.



Jenkins 2.121.1 (running as a systemd unit on master and a remote build node through SSH Slave plugin)

Docker Pipeline plugin 1.17 (released in May 2018)

Docker CE 18.03 running on CentOS 7.5

 




pipeline {

    agent { dockerfile true }

    stages {

        stage('Test') {

            steps {

                sh 'cd /app && npm test'

            }

        }

    }

} 





And then the test stage doesn't run inside the Docker container that was started:
