This page explains how to uninstall Anthos Service Mesh.
Uninstalling Anthos Service Mesh
Use the following commands to uninstall the Anthos Service Mesh components that
were installed with the original configuration profile. These commands also
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.
Remove the control plane, by choosing one of these next steps, depending on your configuration:
If you installed Anthos Service Mesh on Anthos clusters on VMware, Anthos clusters on AWS, Amazon Elastic Kubernetes Service, or Microsoft Azure Kubernetes Service:
istioctl manifest generate --manifests=YOUR_MANIFESTS_DIRECTORY --set profile=asm-multicloud | kubectl delete --ignore-not-found=true -f -
If you installed Anthos Service Mesh on Google Kubernetes Engine:
istioctl manifest generate --manifests=YOUR_MANIFESTS_DIRECTORY --set profile=asm-gcp | kubectl delete --ignore-not-found=true -f -
Delete the
istio-system
namespace:kubectl delete namespace istio-system
Check if the deletion was successful:
kubectl get ns
The output should indicate a
Terminating
state and return as shown, otherwise you might have to manually delete any remaining resources in the namespace and try again.NAME STATUS AGE istio-system Terminating 71m
Turn off sidecar auto-injection on your namespace(s), if it is enabled:
kubectl get namespace YOUR_NAMESPACE --show-labels
The output is similar to the following:
NAME STATUS AGE LABELS demo Active 4d17h istio.io/rev=asm-181-5
If you see
istio.io/rev=
in the output under theLABELS
column, remove it:kubectl label namespace YOUR_NAMESPACE istio.io/rev-
If you see
istio-injection
in the output under theLABELS
column, remove it:kubectl label namespace YOUR_NAMESPACE istio-injection-
If you don't see either the
istio.io/rev
oristio-injection
labels, then auto-injection wasn't enabled on the namespace.
