Deploy Redis to your local

Below steps are running on MacOS. It might now work if you're using Windows OS.

Run redis docker image

>> docker run --rm -ti --name test-redis -p 6379:6379 redis:6.2-rc3-alpine

Check running container

>> docker ps

CONTAINER ID   IMAGE                  COMMAND                  CREATED          STATUS          PORTS                    NAMES
ccc47d8fe03e   redis:6.2-rc3-alpine   "docker-entrypoint.s…"   38 seconds ago   Up 37 seconds   0.0.0.0:6379->6379/tcp   test-redis

Attach another processor to open console in the container

>> docker exec -ti <CONTAINER ID> <command>
>> docker exec -ti ccc47d8fe03e sh

Enter redis-cli and test

/data # redis-cli

127.0.0.1:6379> ping
PONG

127.0.0.1:6379> set key value
OK

127.0.0.1:6379> get key
"value"

Test using netcat from your local terminal

Test using Java

Import Redis Java driver using maven

https://mvnrepository.com/artifact/redis.clients/jedis

        <!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>3.3.0</version>
        </dependency>

Sample Java program

import redis.clients.jedis.Jedis;

public class RedisTest {

    public static void main(String[] args){
        //Connecting to Redis server on localhost
        Jedis jedis = new Jedis("localhost");

        System.out.println("Connection to server sucessfully");
        //check whether server is running or not
        System.out.println("Server is running: "+jedis.ping());
    }
}
