#### Calico

For Calico, you must also modify the settings to allow source spoofing:

- if deployed by operator,  `kubectl patch felixconfigurations default --type='json' -p='[{"op": "add", "path": "/spec/workloadSourceSpoofing", "value": "Any"}]'`
- if deployed by manifest, add env `FELIX_WORKLOADSOURCESPOOFING` with value `Any` in `spec.template.spec.containers.env` for daemonset `calico-node`. (This will allow PODs with specified annotation to skip the rpf check. )

```yaml
meshConfig:
  accessLogFile: /dev/stdout
```

#### Revisions

Control plane revisions allow deploying multiple versions of the control plane in the same cluster.
This allows safe [canary upgrades](https://istio.io/latest/docs/setup/upgrade/canary/)

```yaml
revision: my-revision-name

  // e.g. ["ro", "soft"]. Not validated -
  // mount of the PVs will simply fail if one is invalid.
  // +optional
  repeated string mountOptions = 5;

  // allowVolumeExpansion shows whether the storage class allow volume expand.
  // +optional
  optional bool allowVolumeExpansion = 6;

  // volumeBindingMode indicates how PersistentVolumeClaims should be
  // provisioned and bound.  When unset, VolumeBindingImmediate is used.
