To install and configure Redis in Docker, you can follow these steps:

  1. Firstly, make sure you have Docker installed. If it’s not installed, refer to the official Docker documentation for installation instructions.
  2. Open the terminal or command prompt window, and run the following command to download the Redis image.
  3. Fetch the Redis image using Docker.
  4. After downloading is complete, run the following command to start the Redis container, specifying a container name (for example, my-redis) and a mapped port number (such as 6379):
  5. Start a new Docker container named “my-redis” running Redis in detached mode on port 6379.
  6. This will start a container named my-redis in the background and map port 6379 of the container to port 6379 of the host.
  7. After a brief wait, the Redis container will start and run.
  8. To configure Redis, you can use a Redis client to connect to the container. Run the following command to start the Redis client:
  9. Run the command “redis-cli” in the container named “my-redis” using Docker.
  10. This will connect to the container named my-redis and start the Redis client.
  11. In the Redis client, you can use various commands to configure settings. For example, you can use the CONFIG SET command to set Redis configuration options. For instance, to set the maximum memory limit for Redis to 1GB, you can run the following command:
  12. Set the maximum memory limit to 1 gigabyte.
  13. After you finish configuring, you can use the CONFIG GET command to check the values of the configuration settings. For example, to view the value of the maximum memory limit, you can run the following command:
  14. Retrieve the maximum memory limit set for the configuration.
  15. This will return the value of the maximum memory limit.
  16. After you have finished all configurations, you can exit the Redis client using the exit command.

This completes the process of installing and configuring Redis in Docker. Please configure based on your specific needs, and dive deeper into learning and understanding with the documentation for Docker and Redis.
