Create a serverless database and collection for MongoDB API for Azure Cosmos DB using Azure CLI
APPLIES TO:
Azure Cosmos DB API for MongoDB
Prerequisites
Use the Bash environment in Azure Cloud Shell. For more information, see Azure Cloud Shell Quickstart - Bash.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you are running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For additional sign-in options, see Sign in with the Azure CLI.
When you're prompted, install Azure CLI extensions on first use. For more information about extensions, see Use extensions with the Azure CLI.
Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.
Sample script
#!/bin/bash
# Reference: az cosmosdb | https://docs.microsoft.com/cli/azure/cosmosdb
# --------------------------------------------------
#
# Create a MongoDB API serverless account database and collection
#
#
# Variables for MongoDB API resources
uniqueId=$RANDOM
resourceGroupName="Group-$uniqueId"
location='westus2'
accountName="cosmos-$uniqueId" #needs to be lower case
serverVersion='4.0' #3.2, 3.6, 4.0
databaseName='database1'
collectionName='collection1'
partitionKey='partition_key'
# Create a resource group
az group create -n $resourceGroupName -l $location
# Create a Cosmos account for MongoDB API
az cosmosdb create \
-n $accountName \
-g $resourceGroupName \
--kind MongoDB \
--server-version $serverVersion \
--default-consistency-level Eventual \
--locations regionName='West US 2' failoverPriority=0 isZoneRedundant=False \
--capabilities EnableServerless
# Create a MongoDB API database
az cosmosdb mongodb database create \
-a $accountName \
-g $resourceGroupName \
-n $databaseName
# Define the index policy for the collection, with _id, wildcard, compound, unique and TTL
printf '
[
{
"key": {"keys": ["_id"]}
},
{
"key": {"keys": ["$**"]}
}
]' > idxpolicy-$uniqueId.json
# Create a MongoDB API collection
az cosmosdb mongodb collection create \
-a $accountName \
-g $resourceGroupName \
-d $databaseName \
-n $collectionName \
--shard $partitionKey \
--idx @idxpolicy-$uniqueId.json
# Clean up temporary index policy file
rm -f "idxpolicy-$uniqueId.json"
Clean up deployment
After the script sample has been run, the following command can be used to remove the resource group and all resources associated with it.
az group delete --name $resourceGroupName
Script explanation
This script uses the following commands. Each command in the table links to command specific documentation.
| Command | Notes |
