#### From a specific node syslog

The CNI plugins are executed by threads in the `kubelet` process.  The CNI plugins logs end up the syslog
under the `kubelet` process. On systems with `journalctl` the following is an example command line
to view the last 1000 `kubelet` logs via the `less` utility to allow for `vi`-style searching:

```console
$ journalctl -t kubelet -n 1000 | less
```

#### GKE via Stackdriver Log Viewer

IstioOperator CR.
1. The controller has additional logic that mirrors istioctl commands like upgrade, but is driven from the declarative
API rather than command line.

### Quick tour of CLI commands

#### Flags

The `istioctl` command supports the following flags:

- `dry-run`: console output only, nothing applied to cluster or written to files.
