About integration of memcached with redmine in docker-compose

[mrmm2021]

Hello,

I'M Trying to integrate this memcached image to my actual redmine:3.4.6 docker image.
I'M using docker-compose with traefik + redmine.
Following the docs I added to my docker-compose:

Memcached:
image: sameersbn/memcached:1.5.6-2
ports:
- "11211:11211"
restart: always

My question is:
Is it necessary to do something else?

docker-compose up
Pulling Memcached (sameersbn/memcached:1.5.6-2)...

I see nothing more about memcached in the log.

Thanks in advance!
