Notifications management with Clever Tools
The Notifications service allows you to choose the events of interest to you and decide where to send corresponding notifications.
Historically and by default, deployment result e-mails (deployment succeeded or failed) were always sent to the owners of an application, namely the user themselves or the organization’s members.
notify-email command of clever-tools, you can choose to disable
this or to restrict it to only some applications.
To do this, you need to delete the hook named Default deployment result e-mails, then add a new one and set it to your liking.
Issue this command to learn more about this:
clever help notify-email.
In the future, this service will also handle credits warning notifications and others to come. You will be able to choose wether or not to receive an e-mail and/or for these events to be forwarded to a web service via a webhook.
A webhook in web development is a method of augmenting or altering the behavior of a web page, or web application, with custom callbacks. These callbacks may be maintained, modified, and managed by third-party users and developers who may not necessarily be affiliated with the originating website or application.
In practical terms, this means that you can choose to receive all deployment result events on an endpoint of your application without having to listen to all events via the Websocket API. No more lost events and having to reconnect to the websocket if and when it fails.
clever-tools has a
webhooks command which allows you to list existing
webhooks, remove one or add a new one.
You can issue this command to learn more about it:
clever help webhooks.
Example: Slack deployment results Webhook
First, you will have to create the Incoming WebHooks integration on Slack:
Let’s go to the custom integrations page, once there go to Incoming WebHooks.
You will find an Add Configuration button on the left which will take you to
the page where you need to configure the integration. You just need to select
the channel where you want the notifications to be posted, then it will show
you the Webhook URL, it starts with
Now, let’s create the Webhook!
Go into the application directory for which you want to receive notifications and there issue this command:
clever webhooks add "deployment results on Slack" https://hooks.slack.com/services/xxxxxx/yyyyyy/zzzzzzzzzzzzz --format slack --event META_DEPLOYMENT_RESULT
The list of values that can be assigned to
META_SERVICE_LIFECYCLE= APPLICATION_STOP, DEPLOYMENT_ACTION_BEGIN, DEPLOYMENT_FAIL, DEPLOYMENT_SUCCESS
META_DEPLOYMENT_RESULT= DEPLOYMENT_FAIL, DEPLOYMENT_SUCCESS
META_SERVICE_MANAGEMENT= ADDON_CREATION, ADDON_DELETION APPLICATION_CREATION, APPLICATION_EDITION, APPLICATION_DELETION`
Get a message in a Slack channel when the deployment for an application failed:
clever webhooks add "The application failed to deploy" https://hooks.slack.com/services/xxxxxx/ --format slack --event DEPLOYMENT_FAIL
Notify your accounting service when credits are added:
clever webhooks add "credits added" https://hooks.slack.com/services/xxxxxx/yyyyyy/zzzzzzzzzzzzz --format raw --event META_CREDITS
All done! You can now push your application (
clever deploy) or restart it
clever restart) and you will see the result of the deployment in your Slack
