Alternative to changing the CIDR ranges:
Note: Istio-proxy demands 2 additional CPU limit for each pod it is part of.
Expected Behavior
After running all steps in the READMEs, Bank of Anthos is deployed in the clusters.
Actual Behavior
Most of the services fails due to lack of resources. e.g.:
The cluster cannot be scaled up to more than 4 machines, due to
IP_SPACE_EXHAUSTED
errors in the instance groups of the node poolsThe configured range for
pod-ip-range
is100.65.64.0/22
which give us only 4 chunks of 256 address to be used per instance see Pod IP addresses infoMost of the Cluster resources are used by Istio
