docker方式
创建并实现项目（此处是使用配置中心项目做案例）：
修改build.gradle文件（使用的docker为阿里云镜像服务）：
buildscript {
ext {
springBootVersion = '2.0.3.RELEASE'
}
repositories {
mavenCentral()
maven { url "https://plugins.gradle.org/m2/" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
classpath('se.transmode.gradle:gradle-docker:1.2') //Build a Docker Image with Gradle
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'docker'
group = 'tanwb'
archivesBaseName = 'config-server'
version = 'latest'
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
maven { url "https://repo.spring.io/milestone" }
maven { url "https://nexus.nroad.com.cn/repository/maven-snapshots/" }
}
ext {
springCloudVersion = 'Finchley.RELEASE'
}
dependencies {
compile('org.springframework.boot:spring-boot-starter')
testCompile('org.springframework.boot:spring-boot-starter-test')
compile('org.springframework.cloud:spring-cloud-config-server')
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
// copy the DockerFile into the build/libs folder
build.doLast() {
copy {
from 'src/main/docker'
into 'build/libs'
}
}
task buildDocker(type: Docker, dependsOn: build) {
push = false
applicationName = archivesBaseName
dockerfile = file('src/main/docker/Dockerfile')
doFirst {
copy {
from jar
into stageDir
}
}
}
在src/main下增加docker目录Dockerfile文件：
# 运行环境
FROM frolvlad/alpine-oraclejdk8:slim
# 时区
RUN apk add --no-cache bash coreutils tzdata && echo "Asia/Shanghai" > /etc/timezone
# 挂载点
VOLUME /tmp
# 复制到容器并改名
ADD config-server-latest.jar app.jar
# 端口映射
EXPOSE 8001
# 修改app.jar的访问时间和修改时间为当前时间。
RUN bash -c 'touch /app.jar'
#指定容器启动程序及参数
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
命令行打包/打标签/推送阿里云（使用的docker为阿里云镜像服务）：
./gradlew buildDocker -x test
docker tag 3cbaf8531b5a registry.cn-hangzhou.aliyuncs.com/tanwb/config-server
docker push registry.cn-hangzhou.aliyuncs.com/tanwb/config-server
推送之前请先登陆一下Docker：
docker login --username=tanwb registry.cn-hangzhou.aliyuncs.com
附服务器的docker-compose.yml配置：
config-server:
container_name: config-server
image: registry.cn-hangzhou.aliyuncs.com/tanwb/config-server
ports:
- 8001:8001
volumes:
- /data/docker2/config/native:/native
entrypoint: java -Djava.security.egd=file:/dev/./urandom -jar /app.jar
environment:
- "TZ=Asia/Shanghai"
以下为jib打包方式：
修改build.gradle文件（使用的docker为阿里云镜像服务）：
buildscript {
ext {
springBootVersion ='2.0.3.RELEASE'
}
repositories {
mavenCentral()
maven { url"https://plugins.gradle.org/m2/" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
plugins {
id 'com.google.cloud.tools.jib' version'0.9.7'
id 'com.gorylenko.gradle-git-properties' version'1.5.1'
}
applyplugin:'java'
applyplugin:'eclipse'
applyplugin:'org.springframework.boot'
applyplugin:'io.spring.dependency-management'
group ='tanwb'
archivesBaseName ='config-server'
version ='latest'
sourceCompatibility =1.8
targetCompatibility =1.8
repositories {
mavenCentral()
maven { url"https://repo.spring.io/milestone" }
maven { url"https://nexus.nroad.com.cn/repository/maven-snapshots/" }
}
ext {
springCloudVersion ='Finchley.RELEASE'
}
dependencies {
compile('org.springframework.boot:spring-boot-starter')
testCompile('org.springframework.boot:spring-boot-starter-test')
compile('org.springframework.cloud:spring-cloud-config-server')
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
def getGitHash = { ->
def stdout =new ByteArrayOutputStream()
exec {
commandLine 'git','rev-parse','--short','HEAD'
standardOutput = stdout
}
return stdout.toString().trim()
}
jib {
from {
image ="registry.cn-hangzhou.aliyuncs.com/tanwb/openjdk-font:8-jdk-alpine"
}
to {
image ="registry.cn-hangzhou.aliyuncs.com/tanwb/config-server:rc1-${getGitHash}"
}
container {
mainClass ='com.config.server.Application'
}
}
命令行使用：
./gradlew jib
执行后提示
Built and pushed image as registry.cn-hangzhou.aliyuncs.com/tanwb/config-server:rc1-b70fb53
BUILD SUCCESSFUL in 6s
4 actionable tasks: 2 executed, 2 up-to-date
附服务器的docker-compose.yml配置：
config-server:
container_name: config-server
image: registry.cn-hangzhou.aliyuncs.com/tanwb/config-server:rc1-b70fb53
ports:
- 8001:8001
volumes:
- /data/docker2/config/native:/native
entrypoint: java -cp /app/libs/*:/app/resources/:/app/classes/ com.config.server.Application
environment:
- "TZ=Asia/Shanghai"
