Editing a flow deployment

You can edit the KPIs, alerts, parameters, size and scale details of your flow deployment under Deployment Settings or using the CDP CLI.

Before you begin

Required Role: DFFlowAdmin
You must have deployed a flow definition in Cloudera DataFlow.

Steps

Go to Deployment Manager > Deployment Settings.
Select KPIs and Alerts to edit KPIs or the alerts they trigger.
Select Sizing and Scaling to change the number of NiFi nodes provisioned for your flow deployment and whether to auto-sclae your flow deployment nodes.
Select Parameters to change flow deployment parameter values.
Click Apply Changes before exiting each tab.

Result

You can confirm by finding the Deployment Update success, in Deployment Alerts.

Before you begin

You have installed CDP CLI.
You have run df list-deployments. The output includes the crn field containing the deployment-crn and the service.crn field containing the environment-crn.
To obtain the configuration-version, you have run the following command, the output of which contains the configurationVersion field containing the configuration-version value:
```
dfworkload get-deployment-configuration 
--environment-crn [***ENVIRONMENT_CRN***] 
--deployment-crn [***DEPLOYMENT_CRN***]
```

Steps

To edit an existing flow deployment, enter:
```
cdp dfworkload update-deployment
          --environment-crn <value>
          --configuration-version <value>
          --deployment-crn <value>
          [--parameter-groups <value>]
          [--auto-scaling-enabled | --no-auto-scaling-enabled]
          [--auto-scale-min-nodes <value>]
          [--auto-scale-max-nodes <value>]
          [--static-node-count <value>]
          [--kpis <value>]
          [--asset-update-request-crn <value>]
```
- [--static-node-count] – Specifies the number of NiFi nodes when autoscaling is not enabled. You can select between 1 and 32 nodes. The default value is 1.
- [--auto-scaling-enabled | --no-auto-scaling-enabled] – Specifies whether you want to enable autoscaling. The default is to disable autoscaling.
  - [--auto-scale-min-nodes] – Specifies the minimum nodes when you have autoscaling enabled. If you have autoscaling enabled, this parameter is required.
  - [--auto-scale-max-nodes] – Specifies the maximum nodes when autoscaling is enabled. If you have autoscaling enabled, this parameter is required.
- [--parameter-groups] – Specifies the location of the parameter group JSON file you, if you are using one for this flow deployment.
- [--kpis] – Specifies the location of the KPIs JSON file, if you are providing KPIs for this flow.

Example of updating your static node count


cdp dfworkload update-deployment \
    --environment-crn $ENVIRONMENT_CRN \
    --deployment-crn $DEPLOYMENT_CRN \
    --configuration-version $CONFIGURATION_VERSION \
    --static-node-count 2

Example of how to use a .json file to update parameter values


cdp dfworkload update-deployment \
    --environment-crn $ENVIRONMENT_CRN \
    --deployment-crn $DEPLOYMENT_CRN \
    --configuration-version $CONFIGURATION_VERSION \
    --parameter-groups file:///tmp/parameter-groups.json
