Seed Data to Cosmos DB in Azure Devops

My question is, Is there any other way I can add data from json file to cosmos DB through devops like powershell/api?

The answer is yes.

We could try to use the Azure powershell task to execute the following powershell scripts:

param([string]$cosmosDbName
     ,[string]$resourceGroup
     ,[string]$databaseName
     ,[string[]]$collectionNames
     ,[string]$principalUser
     ,[string]$principalPassword
     ,[string]$principalTennant)

Write-Output "Loggin in with Service Principal $servicePrincipal"
az login --service-principal -u $principalUser -p $principalPassword -t $principalTennant

Write-Output "Check if database exists: $databaseName"
if ((az cosmosdb database exists -d $databaseName -n $cosmosDbName -g $resourceGroup) -ne "true")
{
  Write-Output "Creating database: $databaseName"
  az cosmosdb database create -d $databaseName -n $cosmosDbName -g $resourceGroup
}

foreach ($collectionName in $collectionNames)
{
  Write-Output "Check if collection exists: $collectionName"
  if ((az cosmosdb collection exists -c $collectionName -d $databaseName -n $cosmosDbName -g $resourceGroup) -ne "true")
  {
    Write-Output "Creating collection: $collectionName"
    az cosmosdb collection create -c $collectionName -d $databaseName -n $cosmosDbName -g $resourceGroup
  }
}

Write-Output "List Collections"
az cosmosdb collection list -d $databaseName -n $cosmosDbName -g $resourceGroup

Then press the three dots after Script Arguments and add the parameters defined in the PowerShell script (put all parameters in Variables):

I was running into the same scenario where I needed to maintain configuration documents in source control and update various instances of Cosmos as they changed. What I ended up doing is writing a python script to read a directory structure, one folder for every collection I needed to update, and then read every json file in the folder and upsert it into Cosmos. From there I ran the python script as part of a multi-stage pipeline in Azure DevOps.
