springboot-docker

基于容器的项目启动

java -Dcluster.name=eom -Dcluster.env=test -Dservice.name=eom-data-service -jar target/eom-data-service.jar

docker配置

1. pom配置docker插件

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <version>1.4.13</version>
    <configuration>
        <repository>${project.artifactId}</repository>
        <dockerfile>Dockerfile</dockerfile>
        <contextDirectory>${project.basedir}</contextDirectory>
        <buildArgs>
            <JAR_FILE>${project.build.finalName}</JAR_FILE>
        </buildArgs>
        <tag>${project.version}</tag>
    </configuration>
</plugin>

2. 打包\构建镜像

mvn clean package dockerfile:build -Dmaven.test.skip=true

3. DockerFile

FROM openjdk:11.0.4 as builder
EXPOSE 8080
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone

ARG JAR_FILE
WORKDIR /${JAR_FILE}
ADD ./target/${JAR_FILE}.jar ./app.jar

VOLUME /${JAR_FILE}/logs
ENV JAVA_OPS -server -Xms1024m -Xmx2048m -XX:CompressedClassSpaceSize=128m -XX:MetaspaceSize=200m -XX:MaxMetaspaceSize=200m \
           -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=logs/${JAR_FILE}.hprof
ENV GC_LOG -Xlog:gc* \
           -XX:+PrintGCDateStamps \
           -XX:+PrintTenuringDistribution \
           -XX:+PrintHeapAtGC \
           -XX:+PrintReferenceGC \
           -XX:+PrintGCApplicationStoppedTime \
           -XX:+UseGCLogFileRotation \
           -XX:NumberOfGCLogFiles=10 \
           -XX:GCLogFileSize=10M \
           -XX:+IgnoreUnrecognizedVMOptions \
           -Xlog:gc:logs/${JAR_FILE}.gc.log

CMD mkdir -p /${JAR_FILE}/logs && mkdir -p /${JAR_FILE}/config && java ${JAVA_OPS} ${GC_LOG} -Djava.security.egd=file:/dev/./urandom -Dserver.port=8080 -Dcluster.name=$cluster_name -Dcluster.env=$cluster_env -Dservice.name=$service_name -Dservice.serial=0.0.1 -jar app.jar

DockerFile 中的 JAR_FILE 指定的是项目名 eom-data-service, 在 docker 容器中 /eom-data-service 即为工作目录, app.jar 和 logs 目录都在该目录下。业务日志配置 /eom-data-service/logs 目录, 这样所有日志都在同一目录了, 挂载到宿主机磁盘即可。

docker 容器中可以统一强制运行在 8080 端口, 根据业务需要run镜像时候通过 -p 对外暴露

4. 登录harbor及推送镜像到仓库

5. docker执行

docker run --rm -d --name=eom-data-service -p 7002:8080 -v /Users/cuishiying/Desktop/logs:/eom-data-service/logs -e cluster_name=eom -e cluster_env=test -e service_name=eom-data-service eom-data-service:0.0.5

---

手动构建docker镜像

docker build -t eom-data-service:0.0.1 .
docker build -t eom-data-service:latest .

登录harbor仓库

docker login 10.10.10.108:80

为docker仓库镜像打tag

docker tag 镜像名:标签 私服地址/仓库项目名/镜像名:标签

docker tag eom-data-service:0.0.1 10.10.10.108:80/test/eom-data-service:0.0.1
docker tag eom-data-service:0.0.1 10.10.10.108:80/test/eom-data-service:latest

将docker镜像推送到harbor仓库

docker push 私服地址/仓库项目名/镜像名:标签

docker push 10.10.10.108:80/test/eom-data-service:0.0.1
docker push 10.10.10.108:80/test/eom-data-service:latest

war包Dockerfile
