#### CRD Watcher

For watches against custom types (CRDs), we want to gracefully handle missing CRDs. Naively starting informers against the missing types would result in errors and blocking startup. Instead, we introduce a "CRD Watcher" component that watches the CRDs in the cluster to determine if they are available or not.

This is consumed in two ways:

	@cp -af ./minio minio-release/$(GOOS)-$(GOARCH)/minio
	@cp -af ./minio minio-release/$(GOOS)-$(GOARCH)/minio.$(VERSION)
	@minisign -qQSm minio-release/$(GOOS)-$(GOARCH)/minio.$(VERSION) -s "${CRED_DIR}/minisign.key" < "${CRED_DIR}/minisign-passphrase"
	@sha256sum < minio-release/$(GOOS)-$(GOARCH)/minio.$(VERSION) | sed 's, -,minio.$(VERSION),g' > minio-release/$(GOOS)-$(GOARCH)/minio.$(VERSION).sha256sum

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Si creas un app como:

```Python hl_lines="3"
{!../../../docs_src/first_steps/tutorial002.py!}
```

y lo guardas en un archivo `main.py`, entonces ejecutarías `uvicorn` así:

cluster. Most K8s platform settings are necessarily component settings.
The available features and the components that comprise each feature are as follows:

| Feature | Components |
|---------|------------|
CRDs, and other cluster wide configs | Base
Traffic Management | Pilot
Security | Pilot
Configuration management | Pilot
AutoInjection | Pilot
Gateways | Ingress gateway
Gateways | Egress gateway

but not their sibling manifest directories.

#### Just apply it for me

The following command generates the manifests and applies them in the correct dependency order, waiting for the
dependencies to have the needed CRDs available:

```bash
istioctl install
```

#### Review the values of a configuration profile

The following commands show the values of a configuration profile:

```bash

#-----------------------------------------------------------------------------
# Target: custom resource definitions
#-----------------------------------------------------------------------------

update-crds:
	bin/update_crds.sh

#-----------------------------------------------------------------------------
# Target: artifacts and distribution
#-----------------------------------------------------------------------------

  // +optional
  optional ValidatingAdmissionPolicyStatus status = 3;
}

// ValidatingAdmissionPolicyBinding binds the ValidatingAdmissionPolicy with paramerized resources.
// ValidatingAdmissionPolicyBinding and parameter CRDs together define how cluster administrators configure policies for clusters.
