This page explains how to uninstall Anthos Service Mesh and open source Istio.
Uninstalling Anthos Service Mesh
Run one of the following commands to uninstall the Anthos Service Mesh components that
were installed with the ASM configuration profile. These commands delete the
istio-system namespace and all custom resource definitions (CRDs), including
any CRDs that you applied. If you created CRDs, make sure you have copies
of them.
If you installed Anthos Service Mesh on Anthos clusters on VMware:
istioctl manifest generate --set profile=asm-onprem | kubectl delete -f -
If you installed Anthos Service Mesh on Google Kubernetes Engine:
istioctl manifest generate --set profile=asm | kubectl delete -f -
