关于docker镜像与宿主机通讯

系统：centos
进程1：nginx (docker容器)
进程2：uwsgi（宿主机）

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    # server unix:///path/to/your/mysite/mysite.sock; # for a file socket
    # server 127.0.0.1:8001; # for a web port socket (we'll use this first)
    server 10.2.20.5:8001;
}

# configuration of the server
server {
    # the port your site will be served on
    listen      8000;
    # the domain name it will serve for
    server_name 127.0.0.1; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste


    location /static {
        alias /usr/share/nginx/html/static; # your Django project's static files - amend as required
        index index.html index.htm;
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /etc/nginx/uwsgi_params; # the uwsgi_params file you installed
    }
}

# mysite_uwsgi.ini file
[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = /home/photo
# Django's wsgi file
module          = photo.wsgi
# the virtualenv (full path)
home            = /home/env/djobjenv
# virtualenv= /home/dj/.virtualenvs/dj
env             =DJANGO_SETTINGS_MODULE=photo.settings_deploy

# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 3
# the socket (use the full path to be safe
socket          = 0.0.0.0:8001
# http            = :8000
# ... with appropriate permissions - may be needed
# chmod-socket    = 664
# clear environment on exit
vacuum          = true

问题 一：两者无法通讯
docker 宿主机属于两台不同的电脑，需要使用内网IP

问题二：文件映射

docker run 
--rm 
-it  
-d 
 -v /home/photo/django.conf:/etc/nginx/conf.d/django.conf   
-v /home/docker_static:/usr/share/nginx/html 
-p 8000:8000  
nginx:1.20.1-alpine
