Like Rounak’s link shows: If this is an infrequent operation, you could loop over the map’s keys and values and return the key(s) that match the value, e.g.:

func keysByValue(m map[string]string, value string) []string {
    var keys []string
    for k, v := range myMap {
        if value == v {
            keys = append(keys, k)
        }
    }
    return keys
}

Like this answer says, if this is a common operation, you’ll want another map to make it more efficient.
