I am able to connect to the confluent kafka cluster using the confluent cli but I am unable to do using the segmentio's kafka-go library. I get the below error.
with SASL: SASL handshake failed: EOF
Here is my function in go
package consumer
import (
"context"
"fmt"
"log"
"os"
"time"
"github.com/segmentio/kafka-go"
"github.com/segmentio/kafka-go/sasl/plain"
)
func Consume(ctx context.Context) {
// create a new logger that outputs to stdout
// and has the `kafka reader` prefix
l := log.New(os.Stdout, "kafka reader: ", 0)
mechanism := plain.Mechanism{
Username: "my-api-key",
Password: "my-api-secret",
}
dialer := &kafka.Dialer{
Timeout: 10 * time.Second,
DualStack: true,
SASLMechanism: mechanism,
}
r := kafka.NewReader(kafka.ReaderConfig{
Brokers: []string{brokerAddress}, // brokerAddress given in confluent cloud cluster settings.
Topic: []string{"steps"}[0],
// assign the logger to the reader
Logger: l,
Dialer: dialer,
})
for {
// the `ReadMessage` method blocks until we receive the next event
msg, err := r.ReadMessage(ctx)
if err != nil {
panic("could not read message " + err.Error())
}
// after receiving the message, log its value
fmt.Println("received: ", string(msg.Value))
}
}
I tried generating new keys, use my account username and password, reduce the partitions but nothing works.
it seems your server's TLS
version is not accepted, you can force go-kafka to accept it using MinVersion
:
dialer := &kafka.Dialer{
Timeout: 10 * time.Second,
DualStack: true,
SASLMechanism: mechanism,
TLS: &tls.Config{
MinVersion: tls.VersionTLS12,
},
}
