multi-project docker build using jib

https://github.com/GoogleContainerTools/jib/tree/master/examples/multi-module

Try.

background

--I think it's common to use com.palantir.docker for gradle, but I didn't know how to make it work with multi project. ――In addition, ECR registration was very troublesome for com.palantir.docker. ――I wanted to use jib.

rootProject--sample1 ← This is the repository that pushes to ECR
           --sample2

I tried it.

https://github.com/GoogleContainerTools/jib/tree/master/jib-gradle-plugin#quickstart Correct it like that while watching. It is important to put apply false in the rootProject plugins. If you do not enter this, an error will occur.

build.gradle(Excerpt from rootProject)

plugins {
    id 'org.springframework.boot' version '2.3.4.RELEASE'
    id 'io.spring.dependency-management' version "1.0.10.RELEASE"
    id 'com.google.cloud.tools.jib' version '2.6.0' apply false
}

ext {
    artifactGroup = 'prototype.app'
    artifactVersion = '1.0.0'
    springBootDependenciesVersion = '2.3.4.RELEASE'
}

/*Common to all projects*/
allprojects {

    ext {
        set('extention', 'jar')
        set('artifactVersion', "${artifactVersion}")
    }

    repositories {
        mavenCentral()
        jcenter()
        gradlePluginPortal()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
}

/*Common to Java projects*/
configure(subprojects) {

    apply plugin: 'java'
    apply plugin: 'java-library'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'
  
    dependencyManagement {
        imports {
            // Spring Boot
            mavenBom "org.springframework.boot:spring-boot-dependencies:${springBootDependenciesVersion}"
        }
        imports {
            // AWS SDK ver 2.X.X
            mavenBom "software.amazon.awssdk:bom:2.14.14"
        }
    }

    dependencies {
        // for Develop
        annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
    }
}

/*Common to Docker projects*/
configure(subprojects - project('sample2') ) {
    apply plugin: "com.google.cloud.tools.jib"
}

build.gradle(sample1 excerpt)

plugins {
    id 'com.google.cloud.tools.jib'
}

jib {
    from {
        image = 'amazoncorretto:11'  
    }
    to {
        image = "XXXXXXXXXXXXXX.dkr.ecr.ap-northeast-1.amazonaws.com/prototype"
    //    tags = ["${artifactVersion}"]       
    }
    container {
        environment = [SPRING_PROFILES_ACTIVE:"prod"]
    }
}

Codebuild is also used, so create buildspec.yml. If you do not create an ECR repository, an error will occur, so I created it with terraform in advance. Also, I usually don't do this, but I added a docker pull and run in the post_build phase to see if it works.

buildspec.yml

version: 0.2

env:
  variables:
    # FIXME:
    AWS_ACCOUNT   : "XXXXXXXXXXXXX"
    IMAGE_REPO    : "prototype"
    TAG           : "latest" 
phases:
  install:
    runtime-versions:
      java: corretto11
    commands:
      - chmod +x ./gradlew
      - touch gradle.properties
      - |
        cat <<EOL >> gradle.properties
        org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m
        EOL
        
      - nohup /usr/local/bin/dockerd --host=unix:///var/run/docker.sock --host=tcp://127.0.0.1:2375 --storage-driver=overlay&
      - timeout 15 sh -c "until docker info; do echo .; sleep 1; done"

  pre_build:
    commands:
      - echo build start on `date`
      - $(aws ecr get-login --no-include-email)
      
  build:
    commands:
      - ./gradlew build 
      - ./gradlew :sample1:jib --info

  post_build:
    commands:
      #For operation check
      - docker pull ${AWS_ACCOUNT}.dkr.ecr.ap-northeast-1.amazonaws.com/${IMAGE_REPO}:${TAG}
      - docker run -p 8080:8080 ${AWS_ACCOUNT}.dkr.ecr.ap-northeast-1.amazonaws.com/${IMAGE_REPO}:${TAG}
      - echo build end on `date`
cache:
  paths:
    - /root/.gradle/caches/**/*
    - /root/.gradle/wrapper/**/*

result

At first, I was hit by the ECR specifications, but it worked. (The log has been modified like that)
