6. Introduction to Docker Networking

Activity 6.01: Leveraging Docker Network Drivers

Solution:

The following is the most common way to complete this activity according to best practices:

1. Use the docker network create command to create a network for the NGINX web server. Call it webservernet and give it a subnet of 192.168.1.0/24 and a gateway of 192.168.1.1:

   $ docker network create webservernet --subnet=192.168.1.0/24 --gateway=192.168.1.1

   This should create the bridge network, webservernet.

2. Use the docker run command to create an NGINX web server. Use the -p flag to forward port 8080 on the host to port 80 on the container instance:

   $ docker run -itd -p 8080:80 --name webserver1 --network webservernet nginx:latest

   This will start the webserver1 container in the webservernet network.

3. Use the docker run command to start an Alpine Linux container named monitor in host networking mode. This way, you will know that the container has access to the host ports...
