前言

本文根据前面所学习的知识，使用Maven插件docker-maven-plugin配合Docker+ Docker Compose完成部署微服务项目。

前期准备工作

  1. Linux虚拟机或云主机（云主机需要关注安全组）
  2. 安装好Docker

  3. 安装好Docker Compose

    部署流程

    Docker开启远程API

    用vim编辑修改docker.service文件

    1. vim /usr/lib/systemd/system/docker.service

    需要修改的部分

    1. ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

    修改后的内容

    1. ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

    重启Docker

    1. systemctl restart docker

    引入插件

    使用脚本

    1. # 在微服务的根目录下运行以下命令，maven插件则会开始构建镜像
    2. mvn clean package

    编写Docker Compose脚本

  4. docker-compose-env.yml脚本，负责基础环境

    1. version: '3'
    2. services:
    3. ronan-nacos:
    4.  image: nacos/nacos-server:1.4.2

    45. networks:
    46. ronan-net:
    47.  driver: bridge

  5. docker-compose-app.yml脚本，负责业务服务

    18. ronan-ums-web:
    19.  image: ronan/ronan-ums-web:20220530
    20.  container_name: ronan-ums-web
    21.  ports:
    22.    - "9096:9096"
    23.  volumes:

    上传脚本文件到服务器

    ```bash

    执行env脚本

    docker-compose -f docker-compose-env.yml up -d

查看env运行容器日志

docker-compose -f docker-compose-env.yml logs —tail 10 -f 容器名

执行app脚本

docker-compose -f docker-compose-app.yml up -d

停止并且删除容器

docker-compose -f docker-compose-app.yml down ```

总结

至此，部署完成
