Docker networking

• Lets create two docker containers
  
• Refer Here for formatting the outputs of inspect section
• Now lets find their ip addresses
  
• Now lets get the ip address of the host (machine where is docker is installed)
  
• Lets find if the container can be pinged from the host
  
• Lets find if the networking between two containers is working or not
  
• Containers by default can communicate with each other using ip addresses but not by names.
• The bridge network is created by default when we install docker
  
  
  
• Lets create a new bridge network
  
• create two containers on the new bridge network
