背景 3 | Hi，JAVA！ 4 | 5 | JAVA 的项目通常都比较繁琐，为了标准化流程与简易化部署，本项目根据官方示例构建一套简易的 JAVA 的开发／运行环境（Ubuntu, Tomcat, Maven and JAVA Stack），最终达到 build，ship，run！ 6 | 7 | ## 依赖 8 | 9 | * [Git](https://git-scm.com/downloads) 10 | * [Docker](https://www.docker.com/products/docker/) `>= 1.12` 11 | * [Docker-Compose](https://www.docker.com/products/docker/) `Windows/macOS 版 Docker 已包含` 12 | 13 | > 由于众所周知的原因，梯子不够坚固的童鞋请使用 [国内镜像](http://get.daocloud.io/) 以及 [加速器](https://www.daocloud.io/mirror.html#accelerator-doc)。 14 | 15 | ## 快速体验 16 | 1. `$ git clone https://github.com/springjk/java-in-docker` 17 | 2. `$ cd java-in-docker` 18 | 3. `$ docker-compose up` 19 | 4. 访问 [http://127.0.0.1](http://127.0.0.1) 20 | 21 | 22 | 23 | ![java-in-docker](http://oac57xnsh.bkt.clouddn.com/java-in-docker.jpg) 24 | 25 | 运维命令： 26 | 27 | ```bash 28 | $ docker-compose help # docker-compose 命令帮助 29 | $ docker-compose up # 创建并启动 docker 编排服务 30 | $ docker-compose down # 停止并移除 docker 编排服务 (更改配置文件时建议使用) 31 | $ docker-compose exec java-maven-tomcat bash # ssh 登入 java 容器 32 | ``` 33 | 34 | 35 | ## 加载项目 36 | 上述方式为体验项目使用，运行的为 `code` 目录下的示例代码，实际使用中我们需要加载自己项目的代码，这里有两种方式：挂载项目目录和导入到项目中，选择一种你喜欢的即可。 37 | 38 | ### 挂载项目目录 39 | 1. 修改 `docker-compose.yml` 中的代码挂载目录为你源代码目录（pom.xml 的父级目录） 40 | 2. `$ docker-compose up` 41 | 42 | ### 导入到项目中 43 | 1. `$ cd {your-project-path}` 44 | 2. `$ git submodule add https://github.com/springjk/java-in-docker` 45 | 2. `$ cd java-in-docker` 46 | 3. `$ docker-compose up` 47 | 48 | ## 数据库信息 49 | * **DB_HOST** : `mysql` 50 | * **DB_PORT** : `3306` 51 | * **DB_NAME** : `docker` 52 | * **DB_USER_NAME** : `root` 53 | * **DB_USER_PWD** : `docker` 54 | 55 | 此处的数据库连接地址 `DB_HOST` 值为 `mysql` 是因为名为 `java-maven-tomcat` 的容器 `link` 了名为 `mysql` 的容器，故 `java-maven-tomcat` 容器中会在自己的 `/etc/hosts` 中添加一条 `1xx.xx.xx.xx mysql` 的 host，这会将 `http://mysql` 这个地址指向 `mysql` 容器的实际内网地址，等效于常见的 `http://localhost` 。 56 | 57 | ## 数据持久化 58 | 容器内的数据会随着容器的销毁而丢失，所以需要配置 `docker-compose.yml` 文件将以下目录同步到你的物理机目录进行持久化： 59 | 60 | * `/root/.m2` Maven 的 jar 包缓存目录，挂载后将无需每次构建时重新下载。 61 | * `/var/lib/mysql` MySQL 的文件存放目录，必须挂载，否则销毁容器后数据丢失。 62 | * `/usr/local/tomcat/logs` Tomcat 的日志目录，挂载后查看日志无须进入容器内部。 63 | 64 | Windows 下挂载目录写法示例：`d:/project/`，macOS 与 Linux 下如挂载目录后出现无法写入则是权限问题，ssh 登陆容器后对文件夹给与写入权限即可。 65 | 66 | ## 项目部署 67 | 数据库信息，暴露端口等信息都在 `docker-compose.yml` 中配置，一切调试完成后可在启动命令后添加 `-d` 参数，让其后台启动，此时如果想实时查看启动日志可以使用 `docker-compose logs -f` 进行查看。 68 | 69 | ``` bash 70 | # 后台启动运行 71 | $ docker-compose up -d 72 | 73 | # 跟踪查看启动日志 74 | $ docker-compose logs -f 75 | ``` 76 | 77 | ## 版本信息 78 | * **JAVA** ：`1.8` 79 | * **MySQL** ：`5.7` 80 | * **Maven** ：`3.3.9` 81 | * **Tomcat** ：`8.5.3` 82 | 83 | 版本信息可在 `Dockerfile` 中进行修改，修改 `Dockerfile` 后需要将 `docker-compose` 中的构建方式改为构建本地镜像： 84 | 85 | ``` bash 86 | # 免构建镜像 87 | #image: registry.cn-hangzhou.aliyuncs.com/springjk/java-maven-tomcat 88 | # 构建本地镜像 89 | build: ./java-maven-tomcat 90 | ``` 91 | 92 | 修改完成后启动时需要重新构建镜像： 93 | 94 | ``` bash 95 | $ docker-compose up --build 96 | ``` 97 | 98 | ##

工作流程 136 | `Dockerfile -->(build)–> Image -->(run)–> Container` 137 | 138 | 1. 构建 MySQL 镜像 139 | 2. 构建 JAVA-Tomcat-Maven 镜像 140 | 3. 挂载 MySQL 数据目录并启动 MySQL 容器 141 | 4. 挂载 JAVA 代码目录并启动 JAVA-Tomcat-Maven 容器 142 | 5. 执行 Maven 的代码构建脚本 `build.sh` 生成 WAR 包并放入 Tomcat 工作目录 143 | 6. 启动 Tomcat 144 | 145 | 更多请参考 [Docker Docs](https://docs.docker.com/)。 146 | 147 | ##
