【Docker】DockerFile文件参考

1、项目结构

dockerFile文件在项目/src/main/docker目录下

2、pom文件

org.apache.maven.plugins

maven-compiler-plugin

8

org.apache.maven.plugins

maven-jar-plugin

com.luck.boot.blog.PackageApplication

false

true

lib/

org.apache.maven.plugins

maven-dependency-plugin

copy-dependencies

prepare-package

copy-dependencies

${project.build.directory}/lib

false

com.spotify

docker-maven-plugin

src/main/docker

/

${project.build.directory}

${project.build.finalName}.jar

maven-antrun-plugin

package

file="target/${project.artifactId}-${project.version}.${project.packaging}">

run

3、dockerFile极简模式

## jdk环境

FROM openjdk:8-jdk-alpine

## 复制文件到镜像

ADD *.jar app.jar

ADD lib /lib

## 运行指令

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

4、dockerFile工作目录模式

FROM openjdk:8-jdk-alpine

## 创建目录，并使用它作为工作目录

RUN mkdir -p /package-service

WORKDIR /package-service

## 复制文件

ADD *.jar app.jar

ADD lib /package-service/lib

## jvm参数

ENV TZ=Asia/Shanghai JAVA_OPTS="-Xms512m -Xmx512m"

## 运行指令

CMD java ${JAVA_OPTS} -Djava.security.egd=file:/dev/./urandom -jar app.jar

5、进入容器指令

docker exec -it 容器ID /bin/sh
