Hi Uman,
This can be achieved with the vCSA REST API. If you had a list of vCenter Servers you could do something like the following;
$Credential = Get-Credential # vSphere SSO Credentials
$colvCenterServer = ("labvc1.pigeonnuggets.com","labvc2.pigeonnuggets.com") # Your vCenter server collection
$auth = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($Credential.UserName+':'+$Credential.GetNetworkCredential().Password))
$head = @{
'Authorization' = "Basic $auth"
}
foreach($vCenterServer in $colvCenterServer){
# Setup the API Session
$SessionURI = "https://" + $vCenterServer + "/rest/com/vmware/cis/session"
$request = Invoke-WebRequest -Uri $SessionURI -Method Post -Headers $head
$token = (ConvertFrom-Json $request.Content).value
$session = @{'vmware-api-session-id' = $token}
# Get a list of the DNS Configuration
$DNSURI = "https://" + $vCenterServer + "/rest/appliance/networking/dns/servers"
$dnsRequest = Invoke-WebRequest -Uri $DNSURI -Method Get -Headers $session
$DNSServers = (ConvertFrom-Json $dnsRequest.Content).value
# Do something with the $DNSServers value returned ?
$DNSServers
}
# To Amend the values use a POST Method replacing the IP as required
$strPOSTValue = @'
{
"config": {
"mode": "is_static",
"servers": [
"192.168.88.10"
]
}
}
'@
foreach($vCenterServer in $colvCenterServer){
# Setup the API Session
$SessionURI = "https://" + $vCenterServer + "/rest/com/vmware/cis/session"
$request = Invoke-WebRequest -Uri $SessionURI -Method Post -Headers $head
$token = (ConvertFrom-Json $request.Content).value
$session = @{'vmware-api-session-id' = $token}
$DNSURI = "https://" + $vCenterServer + "/rest/appliance/networking/dns/servers"
Invoke-WebRequest -Uri $DNSURI -Method Put -Headers $session -Body $strPOSTValue -ContentType "application/json"
}
Hopefully this helps; I would recommend that you check out the API Explorer for vCenter (https://vCenter.tld/apiexplorer/) for more methods. Let me know if you need any further info and please mark this as helpful if it has been. Cheers,
Adrian
