2、编写Dockerfile文件
在子项目根目录下新建
.dockerignore文件
#!/usr/bin/env bash
.idea/
*.iml
/src
.pom.xml
/.git
/.settings
.classpath
.project
.springBeans
target/classes
target/generated-sources
target/generated-test-sources
target/maven-archiver
target/maven-status
target/test-classes
并新建Dockerfile文件
#FROM openjdk:8-jdk-alpine
#FROM java:8
FROM registry.docker-cn.com/library/openjdk:8-jdk-alpine
#作者
MAINTAINER xxx@xxx.com
# 在宿主机的/var/lib/docker目录下创建一个临时文件并把它链接到容器中的/tmp目录。
#VOLUME ["/home/project", "/tmp/data"]
VOLUME /tmp
# 环境变量
ENV WORK_PATH /opt
ENV JAVA_OPTS="-Xms1G -Xmx1G -XX:-HeapDumpOnOutOfMemoryError -XX:+UseConcMarkSweepGC"
ENV ENV="dev"
RUN echo "Asia/Shanghai" > /etc/timezone
RUN mkdir $WORK_PATH
#USER user:group
LABEL maintainer="Indra Basak"
#STOPSIGNAL
#ONBUILD
WORKDIR $WORK_PATH
ARG JAR_FILE
# 将打包好的spring程序拷贝到容器中的指定位置
ADD target/${JAR_FILE} ${WORK_PATH}/app.jar
#COPY target/${JAR_FILE} {WORK_PATH}/app.jar
RUN sh -c 'touch $WORK_PATH/app.jar'
#容器对外暴露8888
EXPOSE 8888
# 容器启动后执行的命令
#启动方式1
#ENTRYPOINT exec java -server $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /opt/app.jar --spring.profiles.active=$ENV --server.port=8070
#启动方式2
#CMD ["-Xms1G -Xmx1G -XX:-HeapDumpOnOutOfMemoryError -XX:+UseConcMarkSweepGC","--spring.profiles.active=dev","--server.port=8070"]
#ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/opt/app.jar"]
#启动方式3
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /opt/app.jar --spring.profiles.active=$ENV --server.port=8070"]
3、打包运行
通过maven插件 dockerfile-maven-plugin 生成docker镜像并运行。
