Docker-compose and docker hanging on jenkins

[Francis Chuang]

I currently have a docker-compose.yml file that is used to perform a
jekyll build using `docker-compose run` as a one-off command:

version: '3.7'
services:
build-site:
image: jekyll/jekyll:3
command: jekyll build
volumes:
- .:/srv/jekyll
volumes:
- ../:/usr/src/calcite

This works really well locally. I just run `docker-compose run
build-site` and it will build the files and terminate after the command
finishes.

The problem is that when I do the same on Jenkins, it hangs. My
jenkinsfile looks like this:

pipeline {
agent {
node {
label 'git-websites'
}
}

environment {
COMPOSE_PROJECT_NAME = "${env.JOB_NAME}-${env.BUILD_ID}"
}

options {
timeout(time: 20, unit: 'MINUTES')
}

stages {
stage('Build') {
steps {
dir ("site") {
sh 'docker-compose --verbose run -e JEKYLL_UID=$(id
-u) -e JEKYLL_GID=$(id -g) build-site'
}
echo "Done generating"
}
}
}
}

When this is executed on Jenkins, the shell step executing
docker-compose never terminates and the echo step never runs. The job
then times out and is killed even though the command in the container
completed successfully.

I also tried to run to run a simple docker command to test: `docker run
alpine whoami`. This prints the current user in the container and hangs.

In addition, I also tried playing around with `tty`, `stdin_open` and
`init` in the docker-compose file, but the step still hangs.

Has anyone gotten docker-compose to work with the shell step? If so, is
there something I am missing?
