Redis Installation on Docker

Prerequisites

To use Docker on your laptop, you need to install Docker Desktop. There is a version for Mac, Windows, and Linux.

Installation

From the terminal, run:

docker pull redis

From the terminal, run:

docker run --name redis-container -p 6379:6379 -d redis:latest

This will create a container with default redis port 6379, you translate the command as:

  • docker run - Run a command in a new container

  • --name <your-container-name> - Assign a name to the container to be created, in this example, it will be named as redis-container

  • -p 6379:6379 - Publish or expose port (-p, --expose). In this example, this binds port 6379 of the container to TCP port 6379 on 127.0.0.1 (localhost) of the host machine (local machine). You can also specify udp and sctp ports.

  • -d redis:latest - Run redis container in background and print container ID

Next, run the command below to show all containers, to verify if the container created is running.

docker ps -a

Example

$ docker run --name redis-container -p 6379:6379 -d redis
