方法一：打包+镜像 部署
- 将要部署的项目及其依赖的项目上传至指定文件夹下
- 要部署的项目添加Docker支持，生成Dockerfile文件
- 将生成的Dockerfile文件上传至要部署项目的同级根目录下
- 运行docker build -t net5v20220304 -f Dockerfile .
- net5v20220304 为构建镜像的镜像名
- Dockerfile 后面跟着一个
.表示当前目录 - 如果Dockerfile文件不是放在部署项目的同级根目录下，需要修改Dockerfile文件相应部分代码
docker build --help

第一次运行，报错
runc: symbol lookup error: runc: undefined symbol: seccomp_api_get
大概意思就是缺少依赖包

安装依赖包
yum install libseccomp-devel
安装好之后，继续运行build命令
第一次部署会拉取dotnet基础镜像
- build成功之后，运行docker run -itd -p 8082:80 net5v20220304

- docker run 成功后，即可在浏览器上访问了
- 需要注意的是买的云服务器，需要添加相应端口安全组规则
方法二：docker基础镜像+挂载文件
- 将要部署的项目发布到文件夹
- 将发布后的文件上传至linux上
- 运行docker run -d -p 8084:80 -v /root/demo/publish:/app –workdir /app mcr.microsoft.com/dotnet/aspnet:5.0 dotnet /app/WebCoreDemo.dll
- /root/demo/publish 为项目发布后的地址（路径）
- WebCoreDemo.dll 为项目dll文件名
- 和第一种方式不同的是第一种部署方式缺少dotnet core环境会自动拉取，而第二种方式需要手动拉取，而且需要拉取符合项目dotnet core环境镜像
- docker pull mcr.microsoft.com/dotnet/aspnet[:version] 手动拉取dotnet core环境命令
- [:version] 为版本号
运行时出错，可以使用 docker logs +容器ID 命令查看错误日志
docker logs --help

Options:
--details Show extra details provided to logs
-f, --follow Follow log output

-t, --timestamps Show timestamps
--until string Show logs before a timestamp (e.g. 2013-01-02T13:23:37Z) or relative (e.g. 42m for 42 minutes)
