I am writing my first Jenkins pipeline using the docker agent. When executing the pipeline, I get the following errors in the log in the Run Docker Image stage (note that Pipeline steps have been removed for clarity):
sh: can't create /data/jenkins/workspace/my-workspace@tmp/durable-01234567/pid: nonexistent directory

Jenkinsfile
Based on what I have been able to determine, the Jenkinsfile appears to be written correctly, but I'm certain it's not.
import groovy.json.*
pipeline {
environment {
COMPOSE_TLS_VERSION = "TLSv1_2"
DOCKER_TLS_VERIFY = 1
DOCKER_CERT_PATH = "/opt/ucp"
DOCKER_HOST = "tcp://my-docker-host.example.com:443"
}
agent any
stages {
stage('Prepare Workspace') {
steps {
script {
step([$class: 'WsCleanup'])
checkout scm
}
}
}
stage('Run Docker Image') {
agent {
docker {
reuseNode true
image 'alpine:3.8'
registryUrl 'https://my-docker-registry.example.com'
registryCredentialsId 'my-docker-credentials'
}
}
steps {
sh 'ls -la'
sh 'printenv'
}
}
}
}
Update
I found this link, which talks about a Docker-in-Docker scenario, but I'm not running Docker-in-Docker.
