Overview ¶
Package tagging builds the shared CUDly tag set applied to AWS Reserved Instance-style commitments at purchase time.
It exists so RDS, ElastiCache, and MemoryDB (all three of which accept a Tags field on their respective PurchaseReserved*OfferingInput types) share ONE source of truth for what that tag set looks like, instead of the byte-for-byte identical `createPurchaseTags` method that used to live on each service client. Each AWS SDK exposes its own `types.Tag` struct (rds/types.Tag, elasticache/types.Tag, memorydb/types.Tag) — distinct Go types with the same underlying shape — so this package returns SDK-agnostic Pair values and each service converts with a 5-line adapter.

Types ¶
type Pair ¶
Pair is a single tag key/value independent of any AWS SDK type.
func PurchasePairs ¶
func PurchasePairs(rec common.Recommendation, purpose, resourceKey, source string) []Pair
PurchasePairs returns the standard CUDly purchase-time tag set:
Purpose = <caller-supplied purpose string>
<resourceKey> = rec.ResourceType // "ResourceType" for RDS,
// "NodeType" for ElastiCache & MemoryDB
Region = rec.Region
PurchaseDate = <today, YYYY-MM-DD>
Tool = CUDly
purchase-automation = source // only when source != ""
The purpose text and resource-type key name differ per service (AWS convention varies — RDS uses "ResourceType", ElastiCache and MemoryDB use "NodeType"; purpose strings describe the product being bought) — those two are the only things each service customizes.
Empty source skips the purchase-automation pair rather than writing an empty value, matching the convention established when the tag was first rolled out (so callers that haven't set a Source don't poison cloud tag inventories).
