Jenkins error "No such property: docker for class: groovy.lang.Binding"

I'm trying to follow this tutorial to create a simple docker environment in as part of my Jenkins pipeline build.

I'm trying to build a couple of Docker images just as a test before I do my maven build. At the moment I have the following Groovy for my Jenkinsfile:

#!groovy

node {

  stage 'Building docker env'
  def dbImage = docker.build('oracle', 'docker/oracle')
  def wlpImage = docker.build('liberty', 'docker/liberty')


  stage 'Running maven build'
  git url: 'https://mysite/myproject.git', branch: 'docker'
  def mvnHome = tool 'maven 3.3.9'
  sh "${mvnHome}/bin/mvn -B clean install"
}

I'm trying to have the Docker build look in the directory "docker/oracle" and call the Dockerfile in that directory, and build the Docker images named oracle, and liberty. At the moment though it's giving me this error:

Any ideas what could be the problem with the docker build command I'm using? (or could it be something I forgot to install in Jenkins?)

Solution

  • The issue was I needed to install the Docker Pipeline plugin in Jenkins.

    To install the plugin using the GUI:

    Dashboard > Manage Jenkins > Manage Plugins > Available (tab) > docker-workflow.
