Automating Starting Services in Apache NiFi and Applying Parameters

Automate all the things! You can call these commands interactively or script all of them with awesome DevOps tools. @Andre Araujo and @dchaffey can tell you more about that.

Enable All NiFi Services on the Canvas

By running this three times, I get any stubborn ones or ones that needed something previously running. This could be put into a loop; check the status before trying again.

nifi pg-list
nifi pg-status
nifi pg-get-services

The NiFi CLI has interactive help available and also some good documentation:

NiFi CLI Toolkit Guide

 

/opt/demo/nifi-toolkit-1.12.1/bin/cli.sh nifi pg-enable-services  -u http://edge2ai-1.dim.local:8080 --processGroupId root  

/opt/demo/nifi-toolkit-1.12.1/bin/cli.sh nifi pg-enable-services  -u http://edge2ai-1.dim.local:8080 --processGroupId root  

/opt/demo/nifi-toolkit-1.12.1/bin/cli.sh nifi pg-enable-services  -u http://edge2ai-1.dim.local:8080 --processGroupId root

 

We could then start a process group if we wanted:

 

nifi pg-start -u http://edge2ai-1.dim.local:8080 -pgid 2c1860b3-7f21-36f4-a0b8-b415c652fc62

 

List all process groups

 

/opt/demo/nifi-toolkit-1.12.1/bin/cli.sh nifi pg-list -u http://edge2ai-1.dim.local:8080

 

List Parameters

 

/opt/demo/nifi-toolkit-1.12.1/bin/cli.sh nifi list-param-contexts -u http://edge2ai-1.dim.local:8080 -verbose

 

Set parameters to set parameter context for a process group; you can loop to do all.

  • pgid => parameter group id
  • pcid => parameter context id

I need to put this in a shell or Python script:

 

/opt/demo/nifi-toolkit-1.12.1/bin/cli.sh nifi pg-set-param-context -u http://edge2ai-1.dim.local:8080 -verbose -pgid 2c1860b3-7f21-36f4-a0b8-b415c652fc62  -pcid 39f0f296-0177-1000-ffff-ffffdccb6d90

 

Example

setupnifi.sh (Github Link)

You could also use the NiFi REST API or Dan's awesome Python API
