.net core 3.1 Docker部署 Nginx

windows 10 安装 Docker Desktop

https://www.docker.com/products/docker-desktop

没有帐号可以新建一下，免费提供一个私有仓库

新建VS 项目

Dockerfile 配置

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80



COPY . /app
ENTRYPOINT ["dotnet", "WebDocker.dll"]

配置好后发布程序

发布成功后，系统会自动推送到仓库中，包括Build命令，VS会替你解决

查看你的镜像

查看本地镜像

Docker images

CentOS 安装 Docker

1. 使用 root 权限登录 Centos。确保 yum 包更新到最新。

   sudo yum update

2. 卸载旧版本(如果安装过旧版本的话)

   sudo yum remove docker  docker-common docker-selinux docker-engine

3. 安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

   sudo yum install -y yum-utils device-mapper-persistent-data lvm2

4. 设置yum源

   sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

5. 可以查看所有仓库中所有docker版本，并选择特定版本安装

   yum list docker-ce --showduplicates | sort -r

6. 安装docker

   sudo yum install docker-ce  #由于repo中默认只开启stable仓库，故这里安装的是最新稳定版17.12.0

7. 启动并加入开机启动

   sudo systemctl start docker
   sudo systemctl enable docker

8. 验证安装是否成功(有client和service两部分表示docker安装启动都成功了)

   docker version

Docker 安装好 输入docker login

用你刚才注册的用户和密码登录

dokcer images

 拉取镜像

docker pull xxx:tag

成功之后运行镜像

docker run -d --restart=always --name myapp -p 5000:80 bch1983410/mydocker :v1

查看运行镜像

docker ps

这时可以访问地址

 拉取nginx

docker pull nginx:latest

创建挂载目录

mkdir -p /data/nginx/{conf,conf.d,html,logs}

编写nginx,conf配置文件，并放在文件夹中
