How to pull nginx from docker and run it only in python script

Question

I'm trying to pull nginx from docker hub using python docker library. After pulling the nginx i want to run it and configure it to test some RestAPI requests - only basic ones to get response (200 OK).

What i already have is the following:

img = client.images.pull('nginx:latest')
client.containers.run(img, detach=True)

After these lines i can see the new docker in the list got here:

client.containers.list()

currently there is nothing happened, got nothing in http://localhost:8080. what do i missed? how to configure this nginx in the docker with the python library?

Update and more info:
The solution of the port was very helpful.
Now i can send GET request and get a response with "200 OK"
But now when i'm trying to send POST request i got "405 Not Allowed".
In a quick search in google i found that i need to configure nginx.config in this way:

server {
    listen       80;
    server_name  localhost;

    location / {
        root   html;
        index  index.html index.htm;
    }

    error_page  404     /404.html;
    error_page  403     /403.html;

    # To allow POST on static pages
    error_page  405     =200 $uri;

    # ...
}

My question now is how can i config this file with the docker API? Is this the right solution? replace 405 with 200??

Thanks.

Port binding need to be set. Try the following command:

client.containers.run(img, detach=True, ports={'80/tcp': 8080})

The ports parameter tells the Docker Daemon to expose port 80 inside the Nginx container as port 8080 on the host.

I recommend you going through the API reference first: https://docker-py.readthedocs.io/en/stable/containers.html

You have to set the port mapping during containers.run() setting.
