Any ideas to integrate the Kubernetes cluster on rancher with Sysdig Inspect
I'm not really sure what you mean by 'integrate', but it's pretty straightforward.
Install Sysdig on all your Kubernetes nodes then run it and create capture files. Grab those capture files and load them up on Sysdig inspect
If you'd like a more seamless integration where the capture files are stored in something like S3 and examine them from there, you will have to go with Sysdig's paid product.
