#### 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. )

## Read the Tutorial first

The next sections assume you already read the main [Tutorial - User Guide: Security](../../tutorial/security/index.md){.internal-link target=_blank}.

```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

  ).int().default(DEFAULT_TIMEOUT)

  val followRedirects: Boolean by option("-L", "--location", help = "Follow redirects").flag()

  val allowInsecure: Boolean by option("-k", "--insecure", help = "Allow connections to SSL sites without certs").flag()

  val showHeaders: Boolean by option("-i", "--include", help = "Include protocol headers in the output").flag()
