该博客记录了在CentOS7下启动mysql5.6的Docker容器及部署spring boot项目的过程。包括下载mysql5.6镜像、处理网络连接问题、关闭防火墙以连接数据库，还介绍了将spring boot项目打成jar包、构建Dockerfile、启动容器及端口映射等操作。
笔记：CentOS7下启动一个mysql5.6的Docker容器
虚拟机centOS7
安装docker省略
下载mysql5.6镜像，启动镜像
[root@localhost ~]# docker pull mysql:5.6
[root@localhost ~]# docker run --name mysql5.6v2 -p 3306:3306 \
-e MYSQL_ROOT_PASSWORD=root -d mysql:5.6

虚拟机的IP地址为 192.168.30.128 docker配置的是 -p 3306:3306 所以映射的是虚拟机的ip
用主机ping一下试试
PS C:\WINDOWS\system32> ping 192.168.30.128
正在 Ping 192.168.30.128 具有 32 字节的数据:
来自 192.168.182.140 的回复: 无法访问目标主机。
来自 192.168.30.128 的回复: 字节=32 时间<1ms TTL=64
来自 192.168.30.128 的回复: 字节=32 时间<1ms TTL=64
来自 192.168.30.128 的回复: 字节=32 时间<1ms TTL=64
192.168.30.128 的 Ping 统计信息:
数据包: 已发送 = 4，已接收 = 4，丢失 = 0 (0% 丢失)，
往返行程的估计时间(以毫秒为单位):
最短 = 0ms，最长 = 0ms，平均 = 0ms
如果ping不通可以添加一下路由
PS C:\WINDOWS\system32> route add 192.168.30.0 mask 255.255.255.0 192.168.182.140
操作完成!
然后就通啦
这时候打开主机的navicat连接
可能会出现连不上的问题，可能是虚拟机防火墙的问题
[root@localhost ~]# firewall-cmd --list-ports
[root@localhost ~]#
[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
Warning: ALREADY_ENABLED: 3306:tcp
success
[root@localhost ~]# firewall-cmd --list-ports
[root@localhost ~]# netstat -tln

关掉防火墙，欧克连上了
spring boot项目部署
将项目打成jar包，命令
mvn clean package
构建一个Dockerfile
FROM java:8
VOLUME /tmp
ADD asset-api1-0.3.0.jar app.jar
RUN bash -c "touch /app.jar"
EXPOSE 1213
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
把Dockerfile和打好的jar包放在当前目录下
docker build -t 镜像名 .
镜像构造完成后，启动容器
docker run -it -p 6666:1213--name 容器名 镜像名 bash
其中-p表示端口映射 6666代表容器暴露在外面的端口 1213是容器里程序跑在了哪个端口
意思就是通过 主机ip:6666 就可以访问到 docker容器里的1213端口
大功告成！
