kafka容器化部署

1.参考https://github.com/wurstmeister/kafka-docker的实现。
2.参考https://github.com/simplesteph/kafka-stack-docker-compose
3.基于上述两个参考，实现以下的部署文件。

4.测试文件
基于https://github.com/segmentio/kafka-go库的示范，实现如下：

package kaf

import (
	"context"
	"fmt"
	"github.com/segmentio/kafka-go"
	"log"
	"time"
)

func LeaderProduce() {
	topic := "my-topic"
	partition := 0

	conn, err := kafka.DialLeader(context.Background(), "tcp", "localhost:9092", topic, partition)
	if err != nil {
		log.Fatal(err)
	}
	conn.SetWriteDeadline(time.Now().Add(10 * time.Second))
	conn.WriteMessages(
		kafka.Message{Value: []byte(fmt.Sprint("one!", time.Now()))},
		kafka.Message{Value: []byte(fmt.Sprint("two!", time.Now()))},
		kafka.Message{Value: []byte(fmt.Sprint("three!", time.Now()))},
	)

	conn.Close()
}

func LeaderConsumer() {
	topic := "my-topic"
	partition := 0

	conn, _ := kafka.DialLeader(context.Background(), "tcp", "localhost:9092", topic, partition)

	conn.SetReadDeadline(time.Now().Add(10 * time.Second))
	batch := conn.ReadBatch(10e3, 1e6) // fetch 10KB min, 1MB max
	for {
		msg, err := batch.ReadMessage()
		if err != nil {
			break
		}
		fmt.Println(string(msg.Value))
	}

	batch.Close()
	conn.Close()
}

func ClusterProduce(port int) {
	// make a writer that produces to topic-A, using the least-bytes distribution
	w := kafka.NewWriter(kafka.WriterConfig{
		Brokers:  []string{"localhost:9092", "localhost:9093", "localhost:9094"},
		Topic:    "topic-A",
		Balancer: &kafka.LeastBytes{},
	})

	err := w.WriteMessages(context.Background(),
		kafka.Message{
			Key:   []byte("Key-A"),
			Value: []byte(fmt.Sprint("Hello World!", time.Now())),
		},
		kafka.Message{
			Key:   []byte("Key-B"),
			Value: []byte(fmt.Sprint("One!", time.Now())),
		},
	)
	if err != nil {
		fmt.Println(port, "error", err)
	}

	w.Close()
}

func clusterConsume(port int) {
	// make a new reader that consumes from topic-A
	r := kafka.NewReader(kafka.ReaderConfig{
		Brokers:  []string{"localhost:9092", "localhost:9093", "localhost:9094"},
		GroupID:  "consumer-group-id",
		Topic:    "topic-A",
		MinBytes: 1024 * 10, // 10KB
		MaxBytes: 10e6,      // 10MB
	})

	for {
		m, err := r.ReadMessage(context.Background())
		if err != nil {
			fmt.Println(port, "error.....", err)
			time.Sleep(time.Second * 10)
			continue
		}
		fmt.Printf("%v--message at topic/partition/offset %v/%v/%v: %s = %s\n", port, m.Topic, m.Partition, m.Offset, string(m.Key), string(m.Value))
		// time.Sleep(time.Second)
	}

	r.Close()
}
