Docker发布

使用 Docker 部署 Spring Boot

注意

Docker 技术发展为微服务落地提供了更加便利的环境，使用 Docker 部署 Spring Boot 其实非常简单。

项目添加 Docker 支持

plugins 中添加 Docker 构建插件

xml

      <!-- docker打包插件 -->
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>

dockerfile

创建 Dockerfile 文件，Dockerfile 文件用来说明如何来构建镜像。

shell

  FROM openjdk:11-jre
  MAINTAINER acuity acuier@163.com

  RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && echo "Asia/Shanghai" > /etc/timezone

  ARG JAR_FILE="target/XXX-server.jar"  #貌似取不到JAR_FILE

  ADD ${JAR_FILE} /app.jar  # or COPY ${JAR_FILE} /app.jar

  ENTRYPOINT ["java", "-Xmx512m", "-Djava.security.egd=file:/dev/./urandom", "-Ddruid.mysql.usePingMethod=false", "-jar", "/app.jar"]
  CMD ["--spring.profiles.active=docker"]

必要的服务docker-compose.yml示例

使用docker部署的支持服务，
