## 安装docker18.06.1-ce
### 1.添加docker-ce yum源
安装扩展yum功能，以便使用yum-config-manager添加docker软件源信息
```
yum install -y yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
```
### 2.查看当前可以安装docker-ce版本
安装指定版本的格式 ,注意3:xxx 请移除3:    我这里使用docker-ce-18.06.1.ce-3.el7
```
yum list docker-ce --showduplicates | sort -r
yum -y install docker-ce-[VERSION]   
yum install -y docker-ce-18.06.1.ce-3.el7 
```
### 3.启动测试
```
systemctl start docker && systemctl enable docker

## 安装docker-compose
### 1.下载docker-compose
```
curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
```
### 2.赋予docker-compose全局可执行权
```
chmod +x /usr/local/bin/docker-compose && ln -s /usr/local/bin/docker-compose /usr/bin/
docker-compose --version

docker-compose version 1.18.0, build 8dd22a9
```
## docker-compose java项目目录规划
### 1.环境描述
* docker：18.06.1-ce
* docker-comepose：1.18.0
* vue 2 && npm 14.17.3
* java1.8
### 2.文件目录解释
* config目录：config目录内放项目运行所需要挂载进容器的配置文件及数据文件
* import-base-image目录：docker save所保留下的tar归档基础镜像文件，例：java:8、mysql:8、nginx:1.21.3等，还有docker load镜像的脚本
* java目录：每个java项目在java目录内单独一个目录，目录内放置jar包、Dockerfile、build.sh（打包镜像所用脚本）
* docker-compose.yml ： 我所理解的docker-compose.yml跟k8s内的资源清单一样，就是docker-compose编排配置文件
* build_java_image.sh：进入到所有java项目目录内，把jar包打入docker镜像内
### 3.目录层级展示

## docker-compose常用命令
* docker-compose ps ：查看运行容器
* docker-compose up -d ：后台启动容器 && 资源清单有变化镜像有更新可以更新
* docker-compose down -v : 关闭，下线
* docker-compose up -d --build : 更新镜像
