Mount a host project to a container

Upload the project's host demo directory through FileZilla:

 

 

Based on the microsoft/dotnet: latest image, map port 5000 to the host machine port 5000 and mount the host machine demo to the container app directory.

[root@sn ~]# docker run -p 5000:5000 -it -d -v /demo:/app microsoft/dotnet:latest

[root@sn ~]# docker ps

 

 

 

[root@sn ~]# docker exec –ti 4044ea20a695 /bin/bath 

root@630623fd1c84:/app/demo/SN_ITProjectSolution/WA_SNWeb# dotnet run

 

 

Test Results

The IP address 192.168.30.190: 5000 of the external access host automatically jumps to the Docker container 172.17.0.2: 5000, indicating that the deployment is successful.

 

Jump to port 5000 through Nginx Server Load balancer port 80

Install nginx: http://blog.csdn.net/Jenson_/article/details/77896608

Modify the configuration file: vi/usr/local/nginx/conf/nginx. conf

Modify and add code:

http {

    include       mime.types;

    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

    #                  '$status $body_bytes_sent "$http_referer" '

    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;

    #tcp_nopush     on;

    #keepalive_timeout  0;

    keepalive_timeout  65;

    #gzip  on;

     upstream 192.168.30.190 {

     server 192.168.30.190:5000 ;

 }

    server {

        listen       80;

        server_name  192.168.30.190;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {

            root   html;

            index  index.html index.htm;

            proxy_pass http://192.168.30.190;

        }

 

 

Test results:

 

External access to 192.168.30.190 (default port 80) jumps to 192.168.30.190: 5000, 192.168.30.190: 5000 is the ing port of the Docker container 172.17.0.2: 5000.
