Redis in Docker

1. 查询

   docker search redis
   

2. 拉取镜像

   docker pull redis:latest
   

3. 查看

   docker images
   

4. 运行实例

   docker run --name redis -p 6379:6379 -v D:\db\redis:/data  -d redis redis-server --appendonly yes --requirepass "password" 
   

5. 联机测试

   • cli 测试

   docker exec -it redis /bin/bash
   rediscli -h 127.0.0.1 -p 6379
   auth password
   set test 1
   get test 1
   

• Python 测试

# pip install redis
import redis

r = redis.StrictRedis(host='localhost',port=6379,db=0,password='password',decode_responses=True)
r.set('hello','Redis in Docker')
print(r.get('hello'))  # or print(r['hello'])

StrictRedis 实现了大部分官方命令
decode_responses=True 返回字符串，默认是字节

import redis
#使用连接池
pool = redis.ConnectionPool(host='localhost',port=6379,db=0,password='password',decode_responses=True,max_connections=20)
r = redis.Redis(connection_pool=pool)

• Go 测试

package main

import (
    "context"
    "fmt"

    "github.com/go-redis/redis/v8"
)

func main() {
    ctx := context.Background()
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "password",
        DB:       0,
    })

    //Pong
    res, err := client.Ping(ctx).Result()
    if err != nil {
        panic(err)
    }
    fmt.Println(res)

    res, err = client.Get(ctx, "hello").Result()
    if err == redis.Nil {
        fmt.Println("key:hello does not exist")
    } else if err != nil {
        panic(err)
    } else {
        fmt.Println("key:hello " + res)
    }
}
