I've setup my docker to connect with redis. But upon running the application i'm getting this error

Fatal error: Uncaught CredisException: Connection to Redis redis:0 failed after 2 failures.Last Error : (111) Connection refused in /var/www/html/vendor/colinmollenhour/credis/Client.php:475 Stack trace: #0 /var/www/html/vendor/colinmollenhour/credis/Client.php(471): Credis_Client->connect() #1 /var/www/html/vendor/colinmollenhour/credis/Client.php(784): Credis_Client->connect() #2 /var/www/html/vendor/colinmollenhour/credis/Client.php(637): Credis_Client->__call('select', Array) #3 /var/www/html/vendor/colinmollenhour/cache-backend-redis/Cm/Cache/Backend/Redis.php(382): Credis_Client->select(1) #4 /var/www/html/vendor/colinmollenhour/cache-backend-redis/Cm/Cache/Backend/Redis.php(243): Cm_Cache_Backend_Redis->_applyClientOptions(Object(Credis_Client)) #5 /var/www/html/vendor/magento/zendframework1/library/Zend/Cache.php(153): Cm_Cache_Backend_Redis->__construct(Array) #6 /var/www/html/vendor/magento/zendframework1/library/Zend/Cache.php(94): Zend_Cache::_makeBackend('Cm_Cache_Backen...', Array, true, true) #7 /var/www/ht in /var/www/html/vendor/colinmollenhour/credis/Client.php on line 475

Not sure where to modify. Maybe someone here can help me? This is the configuration I have for my docker-compose.yml

version: '3.0'
services:
 web:

And this is the content of my env.php file under app/etc/

Hope someone can help me with this...
