[dns] Implement config and show commands for static DNS. #2737

oleksandrivantsiv · 2023-03-14T13:22:23Z

What I did

Implement config and show commands for static DNS feature. According to sonic-net/SONiC#1262 HLD.

How I did it

Static DNS config commands are implemented in the new config/dns.py file. DNS config commands are available under config dns ... sub-command.
Show commands are implemented in the new show/dns.py file. DNS show commands are available under show dns ... sub-command.

How to verify it

Compile sonic-utilities package. The unit tests will run automatically during the compilation.
Coverage for config/dns.py : 94%
Coverage for show/dns.py : 86%

Previous command output (if the output of a command-line utility has changed)

New command output (if the output of a command-line utility has changed)

# config dns nameserver add 1.1.1.1
# config dns nameserver add 8.8.8.8
# show dns nameserver
  Nameserver
------------
     1.1.1.1
     8.8.8.8

Hi @oleksandrivantsiv , thanks for your work on this PR and the DNS yang model.

Since we are in the process of replacing adhoc validation checks (like your function def is_valid_ip_address) with yang validation, could you please update your PR to reflect this?

Here is the design doc for how we are phasing in yang validation: sonic-net/SONiC#1072

Here is a sample PR to demonstrate changes that would be necessary to your PR: #2604

On a high level, the main steps are:

add if ADHOC_VALIDATION: where you currently have adhoc validation
use the ValidatedConfigDBConnector decorator

Implement unit tests for all added commands. Coverage for config/dns.py : 94% Coverage for show/dns.py : 86%
