Failed to start Docker Virtual Switch container

[thovikeerthi]

Hi,
I am trying to run Docker Virtual Switch image following references from community GIThub link https://github.com/sonic-net/sonic-buildimage/blob/master/platform/vs/README.vsdocker.md . Then facing an error as below. Please suggest.

Steps:

Clone 202305 branch source code

Run command
$ cd sonic-buildimage/plaform/vs/

Using the above shared link, created the docker name space by running following commands:
$ docker run -id --name sw debian bash
$ sudo ./create_vnet.sh -n 2 sw
$ ip netns list

Whenever I attempt to start the VS Docker using command, then error is shown as detailed below.
$ docker run --privileged --network container:sw --name vs -d docker-sonic-vs

Error Message:
sonic@sfsintel:/sonic-path$ docker run --privileged --network container:sw --name vs -d docker-sonic-vs
Unable to find image 'docker-sonic-vs:latest' locally
docker: Error response from daemon: pull access denied for docker-sonic-vs, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

Please help what is the error in my approach.
