Commonly used resource configurations.

Functions

This section is empty.

Types

type AdditionalConnectionDetailsFn 

type AdditionalConnectionDetailsFn func(attr map[string]interface{}) (map[string][]byte, error)

AdditionalConnectionDetailsFn functions adds custom keys to connection details secret using input terraform attributes 

var NopAdditionalConnectionDetails AdditionalConnectionDetailsFn = func(_ map[string]interface{}) (map[string][]byte, error) {
	return nil, nil
}

NopAdditionalConnectionDetails does nothing, when no additional connection details configuration function provided.

type BasePackages 

type BasePackages struct {
	APIVersion []string
	Controller []string
}

BasePackages keeps lists of base packages that needs to be registered as API and controllers. Typically, we expect to see ProviderConfig packages here.

type DefaultResourceFn 

type DefaultResourceFn func(name string, terraformResource *schema.Resource, opts ...ResourceOption) *Resource

DefaultResourceFn returns a default resource configuration to be used while building resource configurations.

type ExternalName 

type ExternalName struct {
	// SetIdentifierArgumentFn sets the name of the resource in Terraform argument
	// map. In many cases, there is a field called "name" in the HCL schema, however,
	// there are cases like RDS DB Cluster where the name field in HCL is called
	// "cluster_identifier". This function is the place that you can take external
	// name and assign it to that specific key for that resource type.
	SetIdentifierArgumentFn SetIdentifierArgumentsFn

	// GetExternalNameFn returns the external name extracted from TF State. In most cases,
	// "id" field contains all the information you need. You'll need to extract
	// the format that is decided for external name annotation to use.
	// For example the following is an Azure resource ID:
	// /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1
	// The function should return "mygroup1" so that it can be used to set external
	// name if it was not set already.
	GetExternalNameFn GetExternalNameFn

	// GetIDFn returns the string that will be used as "id" key in TF state. In
	// many cases, external name format is the same as "id" but when it is not
	// we may need information from other places to construct it. For example,
	// the following is an Azure resource ID:
	// /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1
	// The function here should use information from supplied arguments to
	// construct this ID, i.e. "mygroup1" from external name, subscription ID
	// from providerConfig, and others from parameters map if needed.
	GetIDFn GetIDFn

	// OmittedFields are the ones you'd like to be removed from the schema since
	// they are specified via external name. For example, if you set
	// "cluster_identifier" in SetIdentifierArgumentFn, then you need to omit
	// that field.
	// You can omit only the top level fields.
	// No field is omitted by default.
	OmittedFields []string

	// DisableNameInitializer allows you to specify whether the name initializer
	// that sets external name to metadata.name if none specified should be disabled.
	// It needs to be disabled for resources whose external identifier is randomly
	// assigned by the provider, like AWS VPC where it gets vpc-21kn123 identifier
	// and not let you name it.
	DisableNameInitializer bool
}

ExternalName contains all information that is necessary for naming operations, such as removal of those fields from spec schema and calling Configure function to fill attributes with information given in external name.

type GetExternalNameFn 

type GetExternalNameFn func(tfstate map[string]interface{}) (string, error)

GetExternalNameFn returns the external name extracted from the TF State. 

var IDAsExternalName GetExternalNameFn = func(tfstate map[string]interface{}) (string, error) {

	}
	return "", errors.New("cannot find id in tfstate")
}

IDAsExternalName returns the TF State ID as external name.

type GetIDFn 

type GetIDFn func(ctx context.Context, externalName string, parameters map[string]interface{}, providerConfig map[string]interface{}) (string, error)

GetIDFn returns the ID to be used in TF State file, i.e. "id" field in terraform.tfstate. 

var ExternalNameAsID GetIDFn = func(_ context.Context, externalName string, _ map[string]interface{}, _ map[string]interface{}) (string, error) {
	return externalName, nil
}

ExternalNameAsID returns the name to be used as ID in TF State file.
