Standalone Pipeline Runs

Ozone pipelines are a sequence of tasks that typically do not require approvals. They can be run unmapped to a microservices
Run Pipelines that are typically periodic and do not require gated approvals. Typical use cases include nightly builds and security scans and so on.

Overview

For use cases such as nightly builds, security scans and QA checks, we suggest you encapsulate them into a pipeline individually that can be run on any target Kubernetes cluster.
Ozone supports three sources for executing pipeline:
  • Pipeline runs triggered from Ozone's UI
  • Pipeline runs that are scheduled by the user
  • Pipeline runs that are triggered by external systems and events

Triggering a Pipeline Run from Ozone's UI

For intermittent and on-demand use cases, a person who has permission to execute a pipeline within a project shall have access to trigger an execution with a mouse-click.
To perform an on-demand pipeline run, do the following:
  • Navigate to the Pipelines Section on the sidebar menu
  • Click on Initiate Pipeline Run
  • Specify the following details
    • The microservice that this pipeline shall deploy (optional)
    • The environment that this pipeline shall have access to
    • The cluster that this pipeline shall run on
  • The pipeline should start executing within Ozone studio
  • Observe task logs by double clicking on any task that is currently executing / has finished execution
  • Click on Run Details to inspect input params and results.

Triggering a Pipeline from Schedules

Ozone supports Hourly, Daily and Weekly pipeline runs. To run a pipeline in a scheduled fashion, do the following:
  • Navigate to Schedules
  • Click on "Create Schedule"
  • Enter the schedule name and timing
  • Map it to a pipeline by applying this schedule to a Pipeline resource
  • Map any parameters that this pipeline will require to run
  • Save the schedule

Triggering a Pipeline from external systems and events

In addition to on-demand and scheduled pipeline executions, Ozone offers you a templated way to trigger pipelines (and releases) by listening to events on an external system. Ozone supports the following platforms natively:
Supported External Systems:
  • Bitbucket
    • Supports triggers from Branch Pushes and Pull Requests
  • Github
    • Supports triggers from Branch Pushes and Pull Requests
  • Gitlab
    • Supports triggers from Branch Pushes and Pull Requests
  • Generic
    • Trigger from any external system that is not supported by Ozone (for example, Postman)
To trigger pipelines from systems that are not supported by ozone, setup a generic webhook

Setting Up External Triggers

  • Integrate the supported providers (Github, Gitlab and Bitbucket) from the ecosystem integrations
  • Navigate to the Triggers section
  • Select the triggers tab
  • Select the external system to respond to
  • Select the repositories and events to watch
  • Select the application that it maps to on Ozone
  • Select the pipelines that need to be executed on this webhook being triggered
  • The pipeline executes when the external system triggers it based on the webhook setup and is visible on the pipelines section
  • Click on a pipeline run to view it's current status and logs

Rollback Pipelines

For every pipeline within Ozone, you may choose to optionally link a pipeline that runs in case of a failure within a pipeline run. This can be setup mapped to a template from Pipelines & Tasks -> GUI Editor -> Select rollback Pipeline
