一 安装mysql服务
1.1 拉取镜像
1.拉取： docker pull mysql:5.7.29
2.查看镜像： docker images
1.2 在宿主机创建文件存储mysql
1.创建映射目录：mysql-c5 在/root/export/dockertest 目录下，mkdir -p mysql-c5 ；存储mysql信息
1.3 创建容器
docker run -id --privileged=true \
-p 3306:3306 \
--name=c5_mysql \
-v $PWD/conf:/etc/mysql/conf.d \
-v $PWD/logs:/logs \
-v $PWD/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 \
mysql:5.7.29
1.4 进入容器
root@localhost dockertest]# docker exec -it c5_mysql /bin/bash
root@5d6f5def65ce:/# mysql -uroot -p123456
mysql: [Warning] Using a password on the command line interface can be insecure.

4 rows in set (0.00 sec)
1.5 远程连接
二 微服务工程上传并发布成镜像
2.1 微服务工程创建
配置连接：
3.访问
2.2 将jar包上传服务器
上传前配置文件这里改成： ip改成容器中myql的服务名称，参考docker-compose中定义mysql的服务的名称。
2.连接配置改成容器中mysql的名称
3.上传jar包
2.3 dockerfile文件的编写
注意dockerfile和jar包要放到同一个目录下，这里是在/root/export/dockertest/docker-compose-dir中
2.编写dockerfile的内容： vi spt04-dockerfile
这里的dockerfile的名称为：spt04-dockerfile ；内容如下：
#基础镜像使用java
#FROM java:8
FROM openjdk:8
#作者
MAINTAINER ljf
#volume 制定临时文件目录为/tmp,
VOLUME /tmp
#将jar包添加到容器中并更名为spt-docker。jar
ADD 04-spt-mybaitsplus-fenye-1.0-SNAPSHOT.jar 04-spt-fenye.jar
#运行jar包
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","04-spt-fenye.jar"]
#暴露端口8080作为微服务
EXPOSE 80842.4 通过dockefile生成镜像
1.注意结尾有一个点。说明 -f 为dockerfile的名称 spt04-dockerfile ； 04-spt-fenye-master:1.6为镜像名称。
2.打成镜像： docker build -f spt04-dockerfile -t 04-spt-fenye-master:1.6 .
3. 查看镜像
三 docker-compose 下载安装
3.1 docker-compose的安装
1.、安装Docker Compose
# Compose目前已经完全支持Linux、Mac OS和Windows，在我们安装Compose之前，需要先安装Docker。下面我 们以编译好的二进制包方式安装在Linux系统中。
curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
2. 设置文件可执行权限
chmod +x /usr/local/bin/docker-compose
3.查看版本信息
docker-compose -version
4.卸载Docker Compose
二进制包方式安装的，删除二进制文件即可
rm /usr/local/bin/docker-compose
四 创建docker网络
4.1 创建docker网络
创建网络，让容器之间可以进行互通访问。
1.查看网络 docker network ls
2.创建网络 docker network create ljf_net
[root@localhost docker-compose-dir]# docker network ls
NETWORK ID NAME DRIVER SCOPE
fe668cbe4240 bridge bridge local
ead95c34bb4d host host local
2452f37044ee none null local
[root@localhost docker-compose-dir]# docker network create ljf_net
d9e1593ce665508aa690393a6976ce4165669cbee93c65645fc6056d8765b737
[root@localhost docker-compose-dir]# docker network ls
NETWORK ID NAME DRIVER SCOPE
fe668cbe4240 bridge bridge local
ead95c34bb4d host host local
d9e1593ce665 ljf_net bridge local
2452f37044ee none null local
2 截图
五 编写docker-compose文件
5.1 编写docker-compose文件
1.jar包，dockerfile，docker-compose 这3个文件，需要在同一级目录下。
2.编写docker-compose的内容
1. - /app/microService:/data 不用自己创建，执行后会自动在宿主机和docker自动创建
2. privileged: true 防止容器中mysql没有操作目录的权限而设置
3.networks:
ljf_net:
自己创建，目的让jar包能够访问到myql容器中的服务。
4.通过命令docker-compose config -q 可以判断所写文件格式是否有问题
version: '3'
services:
microService:
image: 04-spt-fenye-master:1.6
container_name: spt01
ports:
- "8084:8084"
volumes:
- /app/microService:/data
networks:
- ljf_net
depends_on:
- mysql
mysql:
image: mysql:5.7.29
environment:
MYSQL_ROOT_PASSWORD: '123456'
MYSQL_ALLOW_EMPTY_PASSWORD: 'no'
MYSQL_DATABASE: 'test-db'
MYSQL_USER: 'root'
MYSQL_PASSWORD: '123456'
ports:
- "3306:3306"
volumes:
- /app/mysql/db:/var/lib/mysql
- /app/mysql/conf/my.cnf:/etc/my.cnf
- /app/mysql/init:/docker-entrypoint-initdb.d
privileged: true
container_name: "mysql07"
command: --default-authentication-plugin=mysql_native_password #解决外部无法访问
networks:
- ljf_net
networks:
ljf_net:
5.2 执行docker-compose命令一键启动
1）执行前确保服务中docker的服务启动。
1.查看docker的服务： systemctl status docker
2.启动docker服务：systemctl start docker
2） 一键启动
[root@localhost docker-compose-dir]# docker-compose up -d
Creating mysql07 ... done
Creating spt01 ... done
[root@localhost docker-compose-dir]# docker ps -a
