How can I create eth account via go-ethereum? - go

Question

I'm running local ethereum node on my localhost on http://127.0.0.1:7545 (using ganache). I create a new account with keystore as below snippet. But, how can my local ethereum node can be aware of that new account? Normally, I can get balances, transactions etc... But I couldn't achieve to awareness of new account and managing them over my network via go-ethereum SDK.
func CreateAccount() {
password := "secret"
ks := keystore.NewKeyStore("./wallets", keystore.StandardScryptN, keystore.StandardScryptP)
account, err := ks.NewAccount(password)
if err != nil {
log.Fatal(err)
}
fmt.Println(account.Address.Hex())
}

In order to make go-ethereum talk to your Ganache client, you need to call Dial, which accepts a provider URL. In the case described, that would be done as follows:
client, err := ethclient.Dial("http://localhost:7545")
if err != nil {
log.Fatal(err)
}
So all together, you would have something like this along with what you are trying to accomplish in creating a new account and having Ganache see it:
func main() {
client, err := ethclient.Dial("http://localhost:7545")
if err != nil {
log.fatal(err)
}
fmt.Println("we have a connection")
}
func CreateAccount() {
ks := keystore.NewKeyStore("./wallets", keystore.StandardScryptN, keystore.StandardScryptP)
password := "secret"
account, err := ks.NewAccount(password)
if err != nil {
log.Fatal(err)
}
fmt.Println(account.Address.Hex())
}
