How to Manage MongoDB Users and Databases in a Database Cluster

To create a database user via the command-line, follow these steps:

1. Install doctl, the DigitalOcean command-line tool.

2. Create a personal access token, and save it for use with doctl.

3. Use the token to grant doctl access to your DigitalOcean account.

                 doctl auth init
               

4. Finally, create a database user with doctl databases user create. The basic usage looks like this, but you'll want to read the usage docs for more details:

                 doctl databases user create <database-cluster-id> <user-name> [flags]
               

   The following example creates a new user with the username example-user for a database cluster with the ID ca9f591d-f38h-5555-a0ef-1c02d1d1e35

                      doctl databases user create ca9f591d-f38h-5555-a0ef-1c02d1d1e35 example-user
                   

To delete a database user via the command-line, follow these steps:

1. Install doctl, the DigitalOcean command-line tool.

2. Create a personal access token, and save it for use with doctl.

3. Use the token to grant doctl access to your DigitalOcean account.

                 doctl auth init
               

4. Finally, delete a database user with doctl databases user delete. The basic usage looks like this, but you'll want to read the usage docs for more details:

                 doctl databases user delete <database-cluster-id> <user-id> [flags]
               

   The following example deletes the user with the username example-user for a database cluster with the ID ca9f591d-f38h-5555-a0ef-1c02d1d1e35

                      doctl databases user delete ca9f591d-f38h-5555-a0ef-1c02d1d1e35 example-user
                   

To create a database user using the DigitalOcean API, follow these steps:

1. Create a personal access token, and save it for use with the API.

2. Send a POST request to https://api.digitalocean.com/v2/databases/{database_cluster_uuid}/users

   cURL

   To create a database user with cURL, call:

   
                   curl -X POST \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
     -d '{"name": "app-01"}' \
     "https://api.digitalocean.com/v2/databases/9cc10173-e9ea-4176-9dbc-a4cee4c4ff30/users"

   Go

   Go developers can use Godo, the official DigitalOcean V2 API client for Go. To create a database user with Godo, use the following code:

   
                   import (
       "context"
       "os"
   
       "github.com/digitalocean/godo"
   )
   
   func main() {
       token := os.Getenv("DIGITALOCEAN_TOKEN")
   
       client := godo.NewFromToken(token)
       ctx := context.TODO()
   
       addUserRequest := &godo.DatabaseCreateUserRequest{
           Name: "app-01",
       }
   
       user, _, err := client.Databases.CreateUser(ctx, "88055188-9e54-4f21-ab11-8a918ed79ee2", addUserRequest)
   
   }

   Python

   
                   import os
   from pydo import Client
   
   client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))
   
   add_user_resp = client.databases.add_user(database_cluster_uuid="ab7bb7a", body={"name": "app-01"})

To delete a database user using the DigitalOcean API, follow these steps:

1. Create a personal access token, and save it for use with the API.

2. Send a DELETE request to https://api.digitalocean.com/v2/databases/{database_cluster_uuid}/users/{username}

   cURL

   To delete a database user with cURL, call:

   
                   curl -X DELETE \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
     "https://api.digitalocean.com/v2/databases/9cc10173-e9ea-4176-9dbc-a4cee4c4ff30/users/app-01"

   }

   client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))
   
   delete_resp = client.databases.delete_user(database_cluster_uuid="aba134a", username="backend_user1")
