Automation basics¶
To demonstrate how Robusta automations work, we will configure an automation that sends Slack messages when deployments change.
Note
If you use the Robusta UI, changes like this are already tracked in the UI by default.
This tutorial explains how that feature works under the hood.
Add the following to your
generated_values.yaml
:
customPlaybooks:
- triggers:
- on_deployment_update: {}
actions:
- resource_babysitter:
omitted_fields: []
fields_to_monitor: ["spec.replicas"]
Perform an upgrade with Helm to apply the new configuration
helm upgrade robusta robusta/robusta --values=generated_values.yaml
Seeing the automation in action¶
Scale one of your deployments:
kubectl scale --replicas NEW_REPLICAS_COUNT deployments/DEPLOYMENT_NAME
Check the slack channel you configured when installing Robusta:

If you setup the Robusta UI, it will appear in the timeline of all alerts and changes:

How the automation works¶
Every automation has three parts.
- triggers:
We chose
on_deployment_update
which runs whenever Kubernetes Deployments are updated- actions:
We chose Resource babysitter which is a builtin action. That action has a parameter
fields_to_monitor
.- sinks:
We didn't configure any sinks, so output is sent to the default sink. This is usually Slack and/or the Robusta UI.
Further customization¶
Try changing the configuration to monitors changes to a deployment's image tag.
Cleanup¶
If you use the Robusta UI, you should disable the automation you configured in this tutorial to prevent duplicates.
A similar automation is already configured by default.
