  • To install Istio on an RKE2 cluster, additional steps are required. For details, see this section.
  • To install Istio in a cluster where project network isolation is enabled, additional steps are required. For details, see this section.
  1. From the Cluster Explorer, navigate to available Charts in Apps & Marketplace
  2. Select the Istio chart from the rancher provided charts
  3. If you have not already installed your own monitoring app, you will be prompted to install the rancher-monitoring app. Optional: Set your Selector or Scrape config options on rancher-monitoring app install.
