Resources

    Resources represent the fundamental units that make up your cloud infrastructure, such as a compute instance, a storage bucket, or a Kubernetes cluster.

    All infrastructure resources are described by one of two subclasses of the Resource class. These two subclasses are:

    • CustomResource: A custom resource is a cloud resource managed by a resource provider such as AWS, Microsoft Azure, Google Cloud or Kubernetes.
    • ComponentResource: A component resource is a logical grouping of other resources that creates a larger, higher-level abstraction that encapsulates its implementation details.

    A resource’s desired state is declared by constructing an instance of the resource:

    let res = new Resource(name, args, options);
    
    let res = new Resource(name, args, options);
    
    res = Resource(name, args, options)
    
    res, err := NewResource(ctx, name, args, opt1, opt2)
    
    var res = new Resource(name, args, options);
    
    var res = new Resource(name, args, options);
    
    resources:
      res:
        type: the:resource:Type
        properties: ...args
        options: ...options
    

    All resources have a required name argument, which must be unique across resources of the same kind in a stack. This logical name influences the physical name assigned by your infrastructure’s cloud provider. Pulumi auto-names physical resources by default, so the physical name and the logical name may differ. This auto-naming behavior can be overridden, if required.

    The args argument is an object with a set of named property input values that are used to initialize the resource. These can be normal raw values—such as strings, integers, lists, and maps—or outputs from other resources. Each resource has a number of named input properties that control the behavior of the resulting infrastructure. To determine what arguments a resource supports, refer to that resource’s API documentation in the Registry.

    The options argument is optional, but lets you control certain aspects of the resource. For example, you can show explicit dependencies, use a custom provider configuration, or import an existing infrastructure.
