Hello,
Currently, custom runner images can only be configured through YAML, as described in the Harness documentation:
  • step:
type: IACMTerraformPlugin
name: apply
identifier: apply
timeout: 2h
spec:
command: apply
image: plugins/private_harness_terraform_plugin # (1)
connectorRef: privateConnector # (2)
We would like to request the ability to add custom runner images directly through the UI, which would improve usability and reduce reliance on YAML configuration. Please let me know if you need any additional details or have questions regarding this request.
