Downloading the troubleshooting tool
This page shows you how to download the troubleshooting tool for
Cloud Service Mesh. To debug and review your Cloud Service Mesh deployment
you need to install the istioctl component for Google Cloud CLI.
Download istioctl
Managed control plane
Update Google Cloud CLI:
gcloudcomponentsupdate
Download the embedded Cloud Service Mesh troubleshooting tool:
gcloudcomponentsinstallistioctl
If you receive error messageYou cannot perform this action because the
Google Cloud CLI component manager is disabled for this installation, you
have previously installed Google Cloud CLI throughDebian/Ubuntu. Use the
following commands instead:
Update Google Cloud CLI
sudoapt-getupdate
Download the embedded Cloud Service Mesh troubleshooting tool:
sudoapt-getinstallgoogle-cloud-sdk-istioctl

Update Google Cloud CLI:\n\n gcloud components update\n\n2. Download the embedded Cloud Service Mesh troubleshooting tool:\n\n gcloud components install istioctl\n\nIf you receive error message `You cannot perform this action because the\nGoogle Cloud CLI component manager is disabled for this installation`, you\nhave previously installed Google Cloud CLI through\n[Debian/Ubuntu](https://cloud.google.com/sdk/docs/install#deb).
