      deploy_result: "{{ result.output }}"

  - name: render_state
    func: render

      output: "{{ vars.state_repo }}/deployed/{{ vars.env }}.yml"
      data:

        timestamp: "{{ now | date \"2006-01-02T15:04:05Z07:00\" }}"
        status: "{{ steps.deploy_app.deploy_result }}"

Generate Report

steps:
  - name: build_report
    func: render
    args:
      template: |
        # Deployment Report
        Date: {{ now | date "2006-01-02" }}
        Environment: {{ vars.env }}
        Version: {{ vars.version }}
        Build ID: {{ steps.build.build_id }}
        Status: {{ steps.deploy.exit_code | eq 0 | ternary "SUCCESS" "FAILED" }}
    outputs:
      report: "{{ result.output }}"

With Sprig Functions

steps:
  - name: render_names
    func: render
