1.14.1.4 Time Triggered Pipeline Patterns

The time resource produces a new version for the time interval that was declared in its definition in the pipeline configuration file.

The two most common usages are having the time resource trigger on an interval:

resources:
- name: trigger-every-3-minutes
  type: time
  source:
    interval: 3m

Or trigger once within a certain time range: 

resources:
- name: trigger-daily-between-1am-and-2am
  type: time
  source:
    start: 1:00 AM
    stop: 2:00 AM
    location: America/Toronto

Check the README of the time resource for more details.

#1 - Single Time Trigger

The following is an example of a pipeline that is triggered by a time resource on a pre-determined interval.

resources:
- name: trigger-every-3-minutes
  type: time
  source:
    interval: 3m

jobs:
- name: run-forrest-run
  plan:
  - get: trigger-every-3-minutes
    trigger: true
  # can add other steps to run in this job

- name: run-bubba-run
  plan:
  - get: trigger-every-3-minutes
    trigger: true
    passed:
      - run-forrest-run
  # can add other steps to run in this job

#2 - Multiple Time Triggers

As an enhancement to the previous sample with a single time trigger, this pipeline example implements two time resource triggers and the ability to manually kick it off outside of the time resources schedules.

The first time you set up a pipeline like this you will need to manually trigger it in order to satisfy the passed constraint of the manual-trigger resource. Once one version is available that satisfies the passed constraint all future triggers by the other resources will work as expected.

resources:
- name: trigger-every-4-minutes
  type: time
  source:
    interval: 4m
- name: trigger-every-10-minutes
  type: time
  source:
    interval: 10m
- name: manual-trigger
  type: time
  source:
    interval: 1m

jobs:
- name: manual-trigger
  plan:
  - put: manual-trigger

- name: run-forrest-run
  plan:
  - get: trigger-every-4-minutes
    trigger: true
  - get: trigger-every-10-minutes
    trigger: true
  - get: manual-trigger
    trigger: true
    passed:
      - manual-trigger
  # can add other steps to run in this job

- name: run-bubba-run
  plan:
  - get: trigger-every-4-minutes
    trigger: true
    passed:
      - run-forrest-run
  - get: trigger-every-10-minutes
    trigger: true
    passed:
      - run-forrest-run
  - get: manual-trigger
    trigger: true
    passed:
      - run-forrest-run
  # can add other steps to run in this job
