Add new service using laravel sail

I have a laravel 8 project created with composer. Then I added laravel sail by composer require laravel/sail and then executed command php artisan sail:install. After sail up command, only mysql container was created and everything works well. But now I want to add redis to my docker container. How can I do this? I have no knowledge with Docker but laravel sail has made it very easy to use Docker. I want to add redis with the help of laravel sail. Is there any way to do that?

you can edit docker-compose.yml

In services:

laravel.test:
    ...
    depends_on:
        - mysql
        - redis
...

    redis:
        image: 'redis:alpine'
        ports:
            - '${FORWARD_REDIS_PORT:-6379}:6379'
        volumes:
            - 'sailredis:/data'
        networks:
            - sail
        healthcheck:
          test: ["CMD", "redis-cli", "ping"]

then finally, in volumes:

volumes:
    sailmysql:
        driver: local
    sailredis:
        driver: local

You can also start a fresh new project with

curl -s "https://laravel.build/example-app?with=mysql,redis" | bash

then refer the generated docker-compose.yml

after you edit, save it then run ./vendor/bin/sail build then only sail up -d
