Menghubungkan ke instance Redis dari VM Compute Engine

Anda dapat terhubung ke instance Redis dari instance VM Compute Engine yang menggunakan jaringan resmi yang sama dengan instance Redis Anda.

Penyiapan

Jika telah menginstal Google Cloud CLI, membuat instance Redis, dan membuat bucket Cloud Storage, Anda dapat melewati langkah-langkah ini.

Instal gcloud CLI dan lakukan inisialisasi:
```
gcloud init
```
Ikuti Panduan Memulai Cepat untuk membuat instance Redis. Catat zona, alamat IP, dan port instance Redis.
Buat bucket Cloud Storage tempat artefak aplikasi untuk aplikasi contoh ini akan diupload. Untuk mengetahui informasi selengkapnya, lihat Membuat bucket.

Mengonfigurasi setelan gcloud untuk aplikasi contoh

Tetapkan project default gcloud ke project aplikasi contoh Anda.
```
gcloud config set project [PROJECT_ID]
```

Contoh aplikasi

Contoh aplikasi server HTTP ini membuat koneksi ke instance Redis dari instance VM Compute Engine.

Clone repositori untuk bahasa pemrograman yang Anda inginkan dan buka folder yang berisi kode contoh:

Go

git clone https://github.com/GoogleCloudPlatform/golang-samples
cd golang-samples/memorystore/redis

Java

git clone https://github.com/GoogleCloudPlatform/java-docs-samples
cd java-docs-samples/memorystore/redis

Node.js

git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples
cd nodejs-docs-samples/memorystore/redis

Python

git clone https://github.com/GoogleCloudPlatform/python-docs-samples
cd python-docs-samples/memorystore/redis

Aplikasi contoh ini menambahkan penghitung Redis setiap kali endpoint / diakses.

Go

Aplikasi ini menggunakan klien github.com/gomodule/redigo/redis. Instal dengan menjalankan perintah berikut:

go get github.com/gomodule/redigo/redis


// Command redis is a basic app that connects to a managed Redis instance.
package main

import (
	"fmt"
	"log"
	"net/http"
	"os"

	"github.com/gomodule/redigo/redis"
)

var redisPool *redis.Pool

func incrementHandler(w http.ResponseWriter, r *http.Request) {
	conn := redisPool.Get()
	defer conn.Close()

	counter, err := redis.Int(conn.Do("INCR", "visits"))
	if err != nil {
		http.Error(w, "Error incrementing visitor counter", http.StatusInternalServerError)
		return
	}
	fmt.Fprintf(w, "Visitor number: %d", counter)
}

func main() {
	redisHost := os.Getenv("REDISHOST")
	redisPort := os.Getenv("REDISPORT")
	redisAddr := fmt.Sprintf("%s:%s", redisHost, redisPort)

	const maxConnections = 10
	redisPool = &redis.Pool{
		MaxIdle: maxConnections,
		Dial:    func() (redis.Conn, error) { return redis.Dial("tcp", redisAddr) },
	}

	http.HandleFunc("/", incrementHandler)

	port := os.Getenv("PORT")
	if port == "" {
		port = "8080"
	}
	log.Printf("Listening on port %s", port)
	if err := http.ListenAndServe(":"+port, nil); err != nil {
		log.Fatal(err)
	}
}

Java

Aplikasi ini berbasis servlet Jetty 3.1.

Library ini menggunakan library Jedis:

<dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>5.1.0</version>
</dependency>

Class AppServletContextListener digunakan untuk membuat kumpulan koneksi Redis yang lama:


package com.example.redis;

import java.io.IOException;
import java.util.Properties;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

@WebListener
public class AppServletContextListener implements ServletContextListener {

  private Properties config = new Properties();

  private JedisPool createJedisPool() throws IOException {
    String host;
    Integer port;
    config.load(
        Thread.currentThread()
            .getContextClassLoader()
            .getResourceAsStream("application.properties"));
    host = config.getProperty("redis.host");
    port = Integer.valueOf(config.getProperty("redis.port", "6379"));

    JedisPoolConfig poolConfig = new JedisPoolConfig();
    // Default : 8, consider how many concurrent connections into Redis you will need under load
    poolConfig.setMaxTotal(128);

    return new JedisPool(poolConfig, host, port);
  }

  @Override
  public void contextDestroyed(ServletContextEvent event) {
    JedisPool jedisPool = (JedisPool) event.getServletContext().getAttribute("jedisPool");
    if (jedisPool != null) {
      jedisPool.destroy();
      event.getServletContext().setAttribute("jedisPool", null);
    }
  }

  // Run this before web application is started
  @Override
  public void contextInitialized(ServletContextEvent event) {
    JedisPool jedisPool = (JedisPool) event.getServletContext().getAttribute("jedisPool");
    if (jedisPool == null) {
      try {
        jedisPool = createJedisPool();
        event.getServletContext().setAttribute("jedisPool", jedisPool);
      } catch (IOException e) {
        // handle exception
      }
    }
  }
}

Class VisitCounterServlet adalah servlet web yang menambahkan penghitung Redis:


package com.example.redis;

import java.io.IOException;
import java.net.SocketException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;

@WebServlet(name = "Track visits", value = "")
public class VisitCounterServlet extends HttpServlet {

  @Override
  public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {
    try {
      JedisPool jedisPool = (JedisPool) req.getServletContext().getAttribute("jedisPool");

      if (jedisPool == null) {
        throw new SocketException("Error connecting to Jedis pool");
      }
      Long visits;

      try (Jedis jedis = jedisPool.getResource()) {
        visits = jedis.incr("visits");
      }

      resp.setStatus(HttpServletResponse.SC_OK);
      resp.getWriter().println("Visitor counter: " + String.valueOf(visits));
    } catch (Exception e) {
      resp.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, e.getMessage());
    }
  }
}

Node.js

Aplikasi ini menggunakan modul redis.

      res.end(`Visitor number: ${reply}\n`);
    });

  .listen(8080);

Python

Aplikasi ini menggunakan Flask untuk penayangan web dan paket redis-py untuk berkomunikasi dengan instance Redis.

Flask==3.0.3
gunicorn==22.0.0
redis==5.0.1
Werkzeug==3.0.3

import logging
import os

from flask import Flask
import redis

app = Flask(__name__)

redis_host = os.environ.get("REDISHOST", "localhost")
redis_port = int(os.environ.get("REDISPORT", 6379))
redis_client = redis.StrictRedis(host=redis_host, port=redis_port)


@app.route("/")
def index():
    value = redis_client.incr("counter", 1)
    return f"Visitor number: {value}"


@app.errorhandler(500)
def server_error(e):
    logging.exception("An error occurred during a request.")
    return (
        """
    An internal error occurred: <pre>{}</pre>
    See logs for full stacktrace.
    """.format(
            e
        ),
        500,
    )


if __name__ == "__main__":
    # This is used when running locally. Gunicorn is used to run the
    # application on Google App Engine and Cloud Run.
    # See entrypoint in app.yaml or Dockerfile.
    app.run(host="127.0.0.1", port=8080, debug=True)

Men-deploy aplikasi ke VM Compute Engine

Buka direktori gce_deployment:

cd gce_deployment

Skrip deployment mengupload artefak ke jalur Cloud Storage. Kemudian, deployment manager akan meluncurkan instance Compute Engine, membuat firewall untuk mengekspos port 8080. Kemudian, skrip startup akan menyiapkan instance.

Tetapkan variabel lingkungan REDISHOST dan REDISPORT:

   export REDISHOST=[REDISHOST]
   export REDISPORT=[REDISPORT]

dengan:

REDISHOST adalah IP instance Redis terkelola.
REDISPORT adalah port instance Redis terkelola secara default 6379.

Tetapkan variabel lingkungan GCS_BUCKET_NAME:

     export GCS_BUCKET_NAME=[BUCKET_NAME]/[PATH]

dengan:

BUCKET_NAME adalah nama bucket Cloud Storage Anda.
PATH adalah jalur opsional untuk direktori tempat Anda ingin menyimpan artefak aplikasi.

Berikut adalah contoh skrip deployment yang men-deploy aplikasi ini di instance VM Compute Engine baru.

Mungkin perlu waktu beberapa menit hingga aplikasi contoh di-deploy di instance Compute Engine yang baru dibuat.

Setelah instance siap dan skrip startup selesai dieksekusi, buka halaman instance Compute Engine dan salin alamat IP Eksternal.

Untuk melihat aplikasi contoh yang Anda deploy, buka http://[EXTERNAL-IP]:8080

Anda dapat menggunakan skrip teardown.sh untuk menghapus instance dan firewall yang dibuat oleh skrip deployment:

gcloud compute instances delete my-instance

gcloud compute firewall-rules delete allow-http-server-8080
