How to extract Harness Feature Flags

Feature Flags on the Harness Platform​

The Harness Platform is continuously evolving, with the product team regularly releasing new features and critical fixes. However, not all features and fixes are immediately available to all customers, as they must undergo thorough testing and validation.

Feature Flags allow specific features of the Harness Platform to be enabled or disabled for individual customer accounts. These flags are managed by the Harness Support team upon request. Many customers frequently inquire about the feature flags enabled for their accounts. This documentation provides guidance on how to retrieve that information.

Tools Needed:​

  • chrome / safari browser
  • curl
  • jq
  • gitbash (if Windows)

  -o ff.json

The above command will write all the json output containing all the feature flags into a file ff.json

  1. Now run below commands to get the relevant list of FFs in shell terminal

    • Feature Flags Enabled
    jq  --raw-output 'map_values(select(.value == "true"))| .[]|[.flag] | @csv' ff.json | sort -u
    • Feature Flags NOT Enabled
    jq  --raw-output 'map_values(select(.value == "false"))| .[]|[.flag] | @csv' ff.json | sort -u
