snow-wait-for-condition

info

This promotion step is only available in Kargo on the Akuity Platform, versions v1.9.0 and above.

This page is for snow-wait-for-condition step. You can wait for a record field on a ServiceNow record to be set to a particular value before proceeding using this step. Check below for other ServiceNow promotion steps.

ServiceNow integration for kargo is a group of promotion steps:

1. snow-create
2. snow-update
3. snow-delete
4. snow-query-for-records
5. snow-wait-for-condition

These steps provide a comprehensive integration with ServiceNow, allowing you to create, update, delete, query for records, and track promotion workflows. This is particularly useful for maintaining traceability between your promotion processes and project management activities.

All the steps above support different record types in ServiceNow including managing Change Requests, Incidents, Problems etc.,. This integration also provides condition tracking through snow-wait-for-condition, making it a powerful tool for promotion workflows that require coordination with project management systems.

Using the API

Most of the time you cannot use the field labels you see in the ServiceNow UI as keys in the REST API. For example, if you want to set the value for the “Short description” field:

You can't use Short description in the REST API. You need to use short_description as the key and set the value via REST API parameters. To find the correct key for a field, right-click on the field and click Configure Dictionary:

column_name is the key:

To see choices available for a particular field e.g., State, right click on the field and click on Show Choice List to see the available choices for use in the steps:

For example New is -1 and Scheduled is -2

Configuration

Credentials

All ServiceNow operations require proper authentication credentials stored in a Kubernetes Secret.

Name	Type	Required	Description
credentials.secretName	string	Y	Name of the Secret containing the ServiceNow credentials in the project namespace.
credentials.type	string	Y	Type of ServiceNow credentials to use for authentication (either api-token or basic).

For credentials.type: api-token the referenced Secret should contain the following keys:

• apiToken: ServiceNow API Token (see this blog post for how to create an API token in ServiceNow).
• instanceURL: Your ServiceNow instance URL.

For credentials.type: basic the referenced Secret should contain the following keys:

• username: Username of the ServiceNow user (you may want to create a user specifically for this integration).
• password: Password of the ServiceNow user (for how to set the password for a user, see this).
• instanceURL: Your ServiceNow instance URL.

Record

Name	Type	Required	Description
tableName	string	Y	Table name of the record type you want to wait on (e.g., incident, problem, change_request).
ticketId	string	Y	Ticket ID (sys_id) of the record you want to monitor.
condition	string	Y	Condition to wait on before proceeding.

Output

This step does not produce any output.

Example

This example waits for a Change Request to be Scheduled (state=-2) before proceeding with promotion:

steps:
  - as: snow-wait-for-condition
    config:
      condition: state=-2
      credentials:
        namespace: kargo-demo
        secretName: snow-creds
        type: api-token
      tableName: change_request
      ticketId: d457fbac6112287007379b57c6b2e60
    uses: snow-wait-for-condition
# promotion steps continue after approval...
  - uses: helm-template
    config:
      path: ./charts
      vars:
        imageTag: "${{ imageFrom(vars.imageRepo).Tag }}"
        environment: "${{ ctx.stage }}"

You can write more complex conditions as well. See the list of supported operators here.

Different E2E Workflows
