The Context in Keep workflows allows you to reference and utilize data dynamically across different parts of your workflow. Context variables give you access to runtime data such as alert details, results from previous steps or actions, and constants defined in your workflow. This capability makes workflows flexible, reusable, and able to handle complex scenarios dynamically.

​
Accessing Context

Context variables can be accessed using curly braces ({{ }}). You can use these variables directly in triggers, steps, and actions. The context includes:
  1. Alert Data: Access data from the alert triggering the workflow.
  2. Incident Data: If the workflow is incident-based, you can access the incident’s attributes.
  3. Steps and Actions Results: Retrieve data produced by previous steps or actions using their unique IDs.

​
Alert Data

You can access attributes of the alert anywhere in the workflow: 
message: "Alert triggered: {{ alert.name }} - Severity: {{ alert.severity }}"

​
Incident Data

For incident workflows, access incident-related context: 
if: "{{ incident.current_tier == 1 }}"

​
Steps Results

Access results from previous steps: 
message: "Query results: {{ steps.get-max-datetime.results }}"

​
Action Results

Retrieve data from completed actions: 
if: "{{ actions.trigger-email.results.success }}"

​
Constants

Define reusable values in the workflow and access them: 
consts:
  alert_message: "Critical system alert!"
  escalation_policy: "tier-1"
  slack_channels:
    sre_team: CH00001
    payments_team: CH00002
actions:
  - name: notify-slack
    if: "{{alert.source}} == 'datadog'"
    provider:
      type: slack
      config: "{{ providers.slack }}"
      with:
        channel: "{{ consts.slack_channels.sre_team }}"
        message: "{{ consts.alert_message }}"

​
Using Context in Loops

When iterating over data in a foreach loop, the context provides foreach.value for the current iteration. For example: 
steps:
  - name: get-alerts
    provider:
      type: keep
      with:
        query: "status == 'firing'"

actions:
  - name: notify-on-alerts
    foreach: "{{ steps.get-alerts.results }}"
    provider:
      type: slack
      with:
        message: "Alert: {{ foreach.value.name }} is firing!"

​
Examples of Context Usage

​
Dynamic Action Execution

Using context to trigger actions conditionally: 
actions:
  - name: escalate-alert
    if: "{{ alert.severity == 'critical' }}"
    provider:
      type: slack
      with:
        message: "Critical alert: {{ alert.name }}"

​
Enriching Alerts

You can use results from a step to enrich an alert 
steps:
  - name: fetch-customer-details
    provider:
      type: mysql
      with:
        query: "SELECT * FROM customers WHERE id = '{{ alert.customer_id }}'"
        single_row: true

actions:
  - name: enrich-alert
    provider:
      type: mock
      with:
        enrich_alert:
          - key: customer_name
            value: "{{ steps.fetch-customer-details.results.name }}"

​
Conditional Logic Based on Step Results

actions:
  - name: trigger-slack
    if: "{{ steps.get-pods.results.0.status.phase == 'Running' }}"
    provider:
      type: slack
      with:
        message: "Pod is running: {{ steps.get-pods.results.0.metadata.name }}"
