注：在下是在统信UOS系统(Ubuntu系统)中安装部署的。

一、Docker安装

1.安装docker:
sudo apt install docker.io

2.查看docker版本：
docker -v 或者 docker --version

 二、Dckerfile文件内容

#Dockerfile文件内容如下：
FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 5005
EXPOSE 443
COPY . .
ENTRYPOINT ["dotnet", "LanTai.System.Hostd.dll"]

RUN sed -i 's/DEFAULT@SECLEVEL=2/DEFAULT@SECLEVEL=1/g' /etc/ssl/openssl.cnf
RUN sed -i 's/MinProtocol = TLSv1.2/MinProtocol = TLSv1/g' /etc/ssl/openssl.cnf
RUN sed -i 's/DEFAULT@SECLEVEL=2/DEFAULT@SECLEVEL=1/g' /usr/lib/ssl/openssl.cnf
RUN sed -i 's/MinProtocol = TLSv1.2/MinProtocol = TLSv1/g' /usr/lib/ssl/openssl.cnf

# install libgdiplus for System.Drawing
RUN apt-get update && \
    apt-get install -y --allow-unauthenticated libgdiplus libc6-dev

三、在VS里面编译发布，然后用工具上传文件到Linux系统。我用的是WinScp，远程登录Linux如果登录不了要运行下命令：sudo service ssh start 这个命令是用来启动ssh的。

四、建立Docker镜像、建立Docker容器

#创建镜像
docker build -t 镜像名称 . 

#查询镜像是否创建成功
docker images

#创建容器
docker run -d -p 5005:5005 --name 容器名称 镜像名称

#查询容器是否创建成功
docker ps -a

五、部署前端Vue项目 

我用的是nginx来跑Vue项目的，先安装nginx

#Nginx安装
docker pull nginx:latest

#查看nginx进程
ps aux|grep nginx

#编译Vue项目
npm run build:prod

然后用工具上传文件到Linux系统。

前端Vue项目Dockerfile内容

FROM nginx

EXPOSE 80
EXPOSE 5006

COPY dist/ /usr/local/nginx/html/
COPY nginx.conf /etc/nginx/nginx.conf

RUN echo 'echo init ok!!'

ENTRYPOINT nginx -g "daemon off;"

nginx.conf内容

worker_processes auto;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
  
#pid        logs/nginx.pid;

    worker_connections  1024;
}

    include       mime.types;
    default_type  application/octet-stream;
  
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '

    keepalive_timeout  65;
  
    #gzip  on;
  
    client_max_body_size   20m;
    server {
        listen       5006;
        server_name  localhost;
  
        #charset koi8-r;
  
        #access_log  logs/host.access.log  main;
     location / {
        root   /usr/local/nginx/html;
        index  index.html index.htm;
        try_files $uri $uri/ /index.html;
        }
        #error_page  404              /404.html;
  
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
  
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}
  
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}
  
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }
  
    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;
  
    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
  
}

六、重复第四步=》建立Docker镜像、建立Docker容器。

到此Linux部署NET5 前后端分离项目就结束了。有问题请留言，谢谢。
