- periodically copy the K8S JWT token for istio-cni on the host to connect to K8S.

        - the file name can be explicitly set by `CNI_CONF_NAME` env var

!!! tip
    The docs UI will interact with the server that you select.

### Disable automatic server from `root_path`

As Ztunnel operates at L4, we only have the destination IP/port (recovered via `SO_ORIGINAL_DST`).
This may be an IP of a Service, a Pod, or something outside the cluster.
Ztunnel will look up the destination from the [addresses](#address-type) it is configured with.

For traffic to unknown addresses, or to workloads that are not a part of the mesh, the traffic will just be passed through as is.

  }

  public void testManualServiceFailureIdempotence() {
    ManualSwitchedService service = new ManualSwitchedService();
    /*
     * Set up a RecordingListener to perform its built-in assertions, even though we won't look at
     * its state history.
     */
    RecordingListener unused = RecordingListener.record(service);
    service.startAsync();
    service.notifyFailed(new Exception("1"));

So, the interactive docs will have all the information from these dependencies too:

## Simple usage

If you look at it, *path operation functions* are declared to be used whenever a *path* and *operation* matches, and then **FastAPI** takes care of calling the function with the correct parameters, extracting the data from the request.

For example, if some code at some point in the middle, in another dependency or in a *path operation*, made a database transaction "rollback" or create any other error, you will receive the exception in your dependency.

So, you can look for that specific exception inside the dependency with `except SomeException`.

In the same way, you can use `finally` to make sure the exit steps are executed, no matter if there was an exception or not.
