Build docker image using Gradle in SpringBoot using Intellij

I have the following dockerfile.

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

This is build.gradle.

buildscript {
    ext {
        springBootVersion = '2.0.0.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath('se.transmode.gradle:gradle-docker:1.2')
    }
}

apply plugin: 'java'
sourceCompatibility = 1.8
targetCompatibility = 1.8
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'docker'



bootJar {
    baseName = 'gs-spring-boot-docker'
    version =  '0.1.0'
}


group = 'com.pai'
version = '0.0.1-SNAPSHOT'

task buildDocker(type: Docker, dependsOn: build){
    push = true
    applicationName = jar.baseName
    dockerfile = file('src/main/docker/Dockerfile')
    doFirst {
        copy {
            from jar
            into stageDir
        }
    }
}

repositories {
    mavenCentral()
}


dependencies {
    compile 'org.springframework.boot:spring-boot-starter-data-jpa'
    compile 'mysql:mysql-connector-java'
    compile group: 'org.apache.commons', name: 'commons-io', version: '1.3.2'
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.security:spring-security-test')
}

Process sync of build.gradle is successful. When I run the following command.

sudo ./gradlew build buildDocker

I get the following error message.

Execution failed for task ':buildDocker'.
> Docker execution failed
  Command line [docker push com.pai/pai201808:0.0.1-SNAPSHOT] returned:
  Get https://com.pai/v2/: dial tcp: lookup com.pai on 127.0.1.1:53: no such host

I think that this could be the issue of wrong import or invalid configurated dockerfile. How can I solve this problem?

Gradle script tries to push docker image to repository which doesn't exist. Do you intend to do that? If not - then just set push = false.

If you want to push the image to some repository, then you have to setup it. You have to check plugin specific settings of pushing image to repository you want.
