- 重新启动一个nginx，将配置文件夹、静态资源文件夹、日志文件夹挂载出来
# 这里如果宿主机没有对应的文件夹，请先创建文件夹
[root@iZwz9a69mvjujb826ezp71Z nginx]# docker run -d --name nginx -p 80:80 -v /usr/local/nginx/conf:/etc/nginx -v /usr/local/nginx/html:/usr/nginx/html -v /usr/local/nginx/logs:/var/log/nginx nginx
- 登录网站验证
部署Tomcat
- 官方运行建议 docker run -it --rm -p 8888:8080 tomcat:9.0
- 我们之前的启动都是后台，停止容器之后，容器还是可以查到，而docker run -it -rm，一般用来测试，用完就删除
# 官方方式启动
[root@iZwz9a69mvjujb826ezp71Z ~]# docker run -it --rm -p 8888:8080 tomcat:9.0

- 刷新界面，发现不是404了
部署ES
- es暴露的端口多
- es十分耗内存
- es的数据一般需要放置到安全目录！挂载
- –net somenetwork ? 网络配置
- 运行命令
# 下载启动elasticsearch
docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:tag
部署MySQL

- 官方启动命令：docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

SpringBoot微服务打包Dokcer镜像
- 构建SpringBoot项目
这里直接使用若依框架的system模块 - 编写dockerfile
FROM java:8COPY *.jar /app.jarCMD ["--server.port=9201"]EXPOSE 9201ENTRYPOINT ["java", "-jar", "/app.jar"]
- 打包应用
[root@VM-0-10-centos ruoyi-modules-system]# ls
Dockerfile ruoyi-modules-system.jar
- 构建镜像
# docker build命令创建镜像
[root@VM-0-10-centos ruoyi-modules-system]# docker build -t sunbai .
