  6. Integrations


Manages ClusterControl integration modules. Starting from version 1.5.0, there are two modules available:

  • 3rd Party Notifications via clustercontrol-notifications package.
  • Cloud Provider integration via clustercontrol-cloud and clustercontrol-clud packages.

3rd Party Notifications

Configures third-party notifications on events triggered by ClusterControl. allowing users to integrate ClusterControl to your company communication channels, incident response systems, and workflow applications. To prevent users from receiving too many notifications, ClusterControl integrations also allow users to send out only specific critical alerts or warnings (see Warning Events and Critical Events).

See also

Supported services are:

Incident management services Chat services Others
PagerDuty Slack Webhook
VictorOps Telegram

Note that events are only created when either of the following occurred:

  • Alarm created
  • Alarm ended

Thus, if you already have alarms raised and then you create, for example, a Slack (or any other) integration, you will never see events for the alarms already raised/created before you created the Slack integration. You will only see alarms created after the integration.

Field Description
Add new integration
  • Opens the service integration, configuration wizard.
Select Service
  • Pick a service that you want to configure. Different service requires a different set of options.
Service Configuration
  • Specify a name for this integration together with the corresponding service key. The service key can be retrieved from the provider’s website. Click on the “Test” button to verify if ClusterControl is able to connect with the service provider.
Notification Configuration
  • Specify the cluster name together with ClusterControl events that you would like to trigger for the incident. You can define multiple values for both fields. Details on the events are described in the following table:
  • Edit the selected integration.
  • Remove the selected integration.

Cloud Providers

Manages resources and credentials for cloud providers. Note that this new feature requires two modules called clustercontrol-cloud and clustercontrol-clud. The former is a helper daemon that extends CMON’s capability of cloud communication, while the latter is a file manager client to upload and download files on cloud instances. Both packages are dependencies of the clustercontrol UI package, which will be installed automatically if does not exist.

ClusterControl Components.

The credentials that have been set up here can be used to:

  • Manage cloud resources (instances, virtual network, subnet)
  • Deploy databases in the cloud
  • Upload backup to cloud storage

To create a cloud profile, click on Add Cloud Credentials and follow the wizard accordingly. Supported cloud providers are:

  • Amazon Web Service
  • Google Cloud Platform
  • Microsoft Azure

Amazon Web Services Credential

The stored AWS credential will be used by ClusterControl to list out Amazon EC2 instances, spin new instances when deploying a cluster, and upload/downloading backups to AWS S3.

To create an access key for your AWS account root user:

  1. Use your AWS account email address and password to sign in to the AWS Management Console as the AWS account root user.
  2. On the IAM Dashboard page, choose your account name in the navigation bar, and then choose My Security Credentials.
  3. If you see a warning about accessing the security credentials for your AWS account, choose to Continue to Security Credentials.
  4. Expand the Access keys (access key ID and secret access key) section.
  5. Choose Create New Access Key. Then choose Download Key File to save the access key ID and secret access key to a file on your computer. After you close the dialog box, you can’t retrieve this secret access key again.
Field Description
Name Credential name.
AWS Key ID Your AWS Access Key ID as described on this page. You can get this from the AWS IAM Management console.
AWS Key Secret Your AWS Secret Access Key as described on this page. You can get this from the AWS IAM Management console.

Comment (Optional) Description of the credential.

AWS Instances

Lists out your AWS instances. You can perform simple AWS instance management tasks directly from ClusterControl, which uses your defined AWS credentials to connect to the AWS API.

Field Description
AWS Credentials Choose which credential to use to access your AWS resources.
Stop Shutdown the instance.
Reboot Restart the instance.
Terminate Shutdown and terminate the instance.


This allows you to conveniently manage your VPC from ClusterControl, which uses your defined AWS credentials to connect to AWS VPC. Most of the functionalities are dynamically populated and integrated to have the same look and feel as the AWS VPC console. Thus, you may refer to the VPC User Guide for details on how to manage AWS VPC.

Field Description
Start VPC Wizard Open the VPC creation wizard. Please refer to Getting Started Guide for details on how to start creating a VPC.
AWS Credentials Choose which credentials to use to access your AWS resources.

Microsoft Azure Credentials

In order to provide access to Azure services, you need to register an application and grant it access to your Azure resources.

  1. Create an application:
    1. log in to Microsoft Azure portal → Azure Active Directory → App registrations → New application registration.
    2. Provide a name and URL for the application. Select “Web app / API” for the type of application you want to create.
    3. After specifying the values, click Create.
  2. Get application ID and authentication key:
    1. From App registrations in Azure Active Directory, select your application.
    2. Copy the Application ID. You should pass that value as application_id.
    3. To generate an authentication key, select Manage → Certificates & secrets → New client secret.
    4. Provide a description of the key and a duration for the key. When done, select Save.
    5. After saving the key, the value of the key is displayed. Copy this value because you are not able to retrieve the key later. Pass this value as client_secret.
  3. Get tenant ID:
    1. Go to Microsoft Azure portal → Azure Active Directory → Properties for your Azure AD tenant.
    2. Copy the Directory ID. Pass this value as tenant_id.

    1. Go to Microsoft Azure portal → Resource groups → Add.
    2.Fill in the values and click Create.
    3. Copy the Resource group name and use it as resource_group in the credentials.
    4. Wait until the Resource group is created and click Go to Resource group → Access control (IAM) → Add → Add Role Assignment.
    5. Select Contributor as a Role then put your application’s name into search input and select it from the list.
    6. Click Save.
  6. Create a storage account (for Upload Backup to Cloud feature):
