Custom Workflow Plugin

These features are part of the utilities plugin.

Cloudify Utilities: Custom-workflow

Description

The custom workflow utility allows you to run list of action as separate workflow.

The plugin supports:

Plugin supports cloudify_custom_workflow.cloudify_custom_workflow.tasks.customwf workflow with such parameters:

nodes_to_runon: List of node names for run action on.
operations_to_execute: List action names for run.

Steps for writing custom workflow

define actions in the nodes

For example on this node we defined two actions “sync_config” and “backup_config” with implementations.

  CPE_A:
    type: cloudify.nodes.ApplicationModule
    relationships:
    - type: cloudify.relationships.contained_in
      target: fake_node
    interfaces:
      custom:
        sync_config:
          implementation: cpe_sync_config.txt
        backup_config:
          implementation: cpe_backup_config.txt

define the workflow:

workflows:
  BackupFlow:
    mapping: cloudify_custom_workflow.cloudify_custom_workflow.tasks.customwf
    parameters:
      nodes_to_runon:
        default:
          - router
          - CPE_A
      operations_to_execute:
        default:
          - custom.sync_config
          - custom.backup_config

Here, a BackupFlow workflow defined, when executing the workflow it will execute sync_config, backup_config actions on router, CPE_A nodes.
