Ops-controller-manager Pipeline Object

The Pipeline object defines a sequence of tasks executed in a specific order. Tasks in a pipeline can reference results from previous tasks using path references.

Create Pipeline Using YAML File

apiVersion: crd.chenshaowen.com/v1
kind: Pipeline
metadata:
  name: app-deploy
  namespace: ops-system
spec:
  desc: "Deploy application to production"
  variables:
    namespace:
      value: "production"
  tasks:
    - name: prepare-config
      taskRef: prepare-config-task
      results:
        config: generate-step
        version: generate-step
    - name: deploy-app
      taskRef: deploy-app-task
      variables:
        config: ${config}
        version: ${version}
    - name: verify-deploy
      taskRef: verify-deploy-task
      variables:
        version: ${version}

In this YAML:

desc: A description of the pipeline.
variables: Pipeline-level variables.
tasks: List of tasks to execute in order:
- name: Task name in the pipeline (used for path references).
- taskRef: Reference to the Task object.
- results: Map of result keys to step names, defining which step outputs to export.
- variables: Task-specific variables (automatically filled by controller). If a task variable has a default value and the pipeline has the same variable, it will be automatically filled here. Results from previous tasks are also automatically available as variables.

Automatic Variable Filling:

When a Pipeline is created or updated, the controller automatically fills variables for each task:

If a task variable has a default value and the pipeline has the same variable, the pipeline value is filled into TaskRef.variables
This makes all variable values visible in the Pipeline spec

Variable References

Results from previous tasks are automatically added to Pipeline variables, so you can reference them directly:

variables:
  config: ${config}      # Direct reference (recommended)
  version: ${version}    # Direct reference (recommended)

You can also use path syntax for explicit references:

variables:
  config: ${tasks.prepare-config.results.config}   # Path reference
  version: ${tasks.prepare-config.results.version} # Path reference
