We going to restore the Istio by extract the current Istio yaml as below and apply with them once the Istio got issue. But is there any official way to restore the entire Istio ( version 1.5.8 and 1.6.x ) ? Thanks.
Backup Istio yaml list :
- CustomResourceDefinition (need modify schema, see appendix 1)
- ServiceAccount (need remove the token value)
