# idyl apply

> Apply resource manifests from a file

Apply resource manifests from a YAML file.

The command creates each resource if it does not exist, or updates it if it
already exists where the resource API supports updates. Supported kinds are
Namespace, Deployment, ReplicaSet, Pod, Job, Sandbox, CronJob, Service, WebApp,
Gateway, HTTPRoute, TLSRoute, ReferenceGrant, and RegistryCredential. A file
can contain multiple YAML documents separated by ---.

Container specs may include imagePullSecret: secret://name or
imagePullSecret: secret://namespace/name for private image pulls.
RegistryCredential manifests must include spec.passwordData with the base64
encoded registry password.

## Usage

```bash theme={null}
idyl apply -f FILENAME [flags]
