heroku 部署 Spring Boot Docker Image
郭凡
准备Docker Image
修改之前创建的Spring Boot 项目, 添加 Docker 插件
build.gradle
plugins {
id 'org.springframework.boot' version '2.2.2.RELEASE'
id 'io.spring.dependency-management' version '1.0.8.RELEASE'
id 'java'
id 'com.palantir.docker' version '0.22.1'
}
group = 'io.arukas'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
bootJar {
baseName = 'spring-boot-heroku-gradle'
version = '0.0.1'
}
docker {
dependsOn build
tags 'latest'
dockerfile file('Dockerfile')
name "ncc0706/${bootJar.baseName}"
files bootJar.archivePath
buildArgs(['JAR_FILE': "${bootJar.archiveName}"])
}
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
}
test {
useJUnitPlatform()
}
新增Dockerfile 文件
FROM ncc0706/jdk:8u131
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} /opt/application.jar
CMD [ "sh", "-c", "java -Dserver.port=$PORT -Xmx300m -Xss512k -Dfile.encoding=UTF-8 -Djava.security.egd=file:/dev/./urandom -jar /opt/application.jar" ]

进入正题开始部署 Docker Image 到 heroku
随意创建一个目录，这里我用的 deploy, 创建2个文件如下
Dockerfile
这里的 Dockerfile 跟刚才创建的不一样哦，就是上面推送到 docker hub 的镜像名称
FROM ncc0706/spring-boot-heroku-gradle
heroku.yml
指定当前目录的 Dockerfile ，如果两个文件不在同一目录需指定相对路径
build:
docker:
web: Dockerfile
初始化仓库
进入 deploy 目录就是上面创建的
# 初始化仓库
$ git init
# 添加文件到本地暂存区
$ git add .
# 提交到本地仓库
$ git commit -am "ready build"
[master (root-commit) 3a1cf00] ready build

# 容器技术部署
$ heroku stack:set container
Stack set. Next release on ⬢ spring-boot-gradle-docker will use container.
Run git push heroku master to create a new release on ⬢ spring-boot-gradle-docker.

从日志看我们已经用Dockerfile 成功部署 Spring Boot ,还是用浏览器看看效果吧，访问地址: https://spring-boot-gradle-docker.herokuapp.com.
