Scenario

This section describes how to deploy a Redis client in a CCSE cluster container and connect it to Redis for access and operation.

Business Requirements

The Redis client needs to be deployed in a container to facilitate management and deployment.
The container orchestration capabilities provided by CCSE are required for HA and load balance.
The Redis client must securely connect to Redis and can read and write data properly.

Environment Preparation

Create a Redis client container image, including Redis client dependencies and configurations.
Create a CCSE cluster and configure necessary network and node resources.
Deploy the Redis client container in the CCSE cluster.
Configure container environment variables and specify information about connecting to Redis.
Run the Redis client container and test the connectivity and data operations.

Implementation Solution

Creating a Redis client container image: Create a Dockerfile, and specify the version and dependencies of the Redis client. Example:

Creating a CCSE cluster: Create a cluster in the CCSE console and configure the necessary network and node resources. Select proper specifications and quantities according to your actual requirements.
Deploying a Redis client container: Use the CCSE console or CLI to deploy a Redis client container in the CCSE cluster that you have created. Specify the Redis client container image created earlier.
Configuring container environment variables: Configure environment variables for connecting to Redis in the client container, including the IP address, port, and password of the Redis server. For example, configure the following environment variables for starting a container:

export REDIS_HOST=your_dcs_host
export REDIS_PORT=your_dcs_port
export REDIS_PASSWORD=your_dcs_password

Testing connection and data operations: Start the Redis client container and use the proper client library and code for tests. For example, use the Jedis client library in Java.

import redis.clients.jedis.Jedis;

public class RedisClientExample {
    public static void main(String[] args) {
        // Get environment variables.
        String host = System.getenv("REDIS_HOST");
        int port = Integer.parseInt(System.getenv("REDIS_PORT"));
        String password = System.getenv("REDIS_PASSWORD");

        // Create a Jedis client instance.
        Jedis jedis = new Jedis(host, port);
        jedis.auth(password);

        // Perform operations on data.
        jedis.set("key", "value");
        String value = jedis.get("key");
        System.out.println("Value: " + value);

        // Close the connection.
        jedis.close();
    }
}

The code example shows how to use a Jedis client library to connect to Redis and perform operations on data. You can use a proper client library based on your needs and programming language, and configure connection parameters based on environment variables.

Through the preceding steps, you can deploy the Redis client in the CCSE cluster container and connect to Redis through CCSE to access and use Redis data.
