and

Add to build.gradle

        buildscript {
            repositories {
                mavenLocal()
                mavenCentral()
                maven { url "https://repo.grails.org/grails/core" }
                maven { url "https://plugins.gradle.org/m2/" }
            }
            dependencies {
                classpath "org.grails:grails-gradle-plugin:$grailsVersion"
                classpath "org.grails.plugins:hibernate5:${gormVersion-".RELEASE"}"
                classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.14.8"
                classpath "gradle.plugin.com.palantir.gradle.docker:gradle-docker:0.19.2"
            }
        }
        apply plugin: "com.palantir.docker"
        docker {
          // name 'hub.docker.com/knowint/resource-sharing-message-services:latest'
          name 'knowint/test2:latest'
          files war.archivePath
          buildArgs(['JAR_FILE':"${war.archiveName}"])
          dockerfile project.file('src/main/docker/Dockerfile')
        }

Add src/main/docker/Dockerfile

        FROM frolvlad/alpine-oraclejdk8:slim
        MAINTAINER Ian.Ibbotson@k-int.com
        VOLUME /tmp
        ADD test2-0.1.war test2.war
        RUN sh -c 'touch /test2.war'
        ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/test2.war"]

Then gradle build docker

will build a docker image.
