garage-k2v-go

Go client for K2V, an experimental small object key-value storage engine built as part of Garage.

Because the K2V API is not stable, breaking changes in this Go module should be expected until then.

Import

import k2v "code.notaphish.fyi/milas/garage-k2v-go"

Create API client

// Read K2V_ENDPOINT from OS environment variable, e.g. http://localhost:3904.
endpoint := k2v.EndpointFromEnv()

// Read K2V_KEY_ID and K2V_KEY_SECRET from OS environment variables.
key := k2v.KeyFromEnv()

// Alternatively, construct a key by initializing the ID and secret fields on a k2v.Key.
// key := k2v.Key{ID: "GK...", Secret: "..."}

client := k2v.NewClient(endpoint, key)
