Docker: MariaDB Container Unhealthy - Impossible to access Database - docker

Question

I am currently getting crazy about my docker-compose really basic configuration which does not work as it should. I am trying to make it so one service depends on the MariaDB container properly loaded, to avoid tables initialization issue. Current state is that, whatever I add as environment variables for the MariaDB container configuration, my custom healthcheck fails and even accessing the container itself, I cannot login to the mariadb server.
The docker-compose looks as follows:
version: "3.9"
services:
dbs:
build: .
ports:
- "8000:8000"
mariadb:
container_name: ${APP_NAME}_mariadb
image: mariadb
restart: always
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_USER: test
MYSQL_PASS: pass
MYSQL_DATABASE: filecoin_dbs
ports:
- 3306:3306
healthcheck:
test: mariadb --user=test --password=pass --silent --execute \"SELECT 1;\"
interval: 1s
timeout: 3s
retries: 3
volumes:
- ./mounts/mariadb:/var/lib/mysql
dbs_filecoin:
container_name: filecoin
build: ./services/dbs_filecoin/
env_file: .env
depends_on:
mariadb:
condition: service_healthy
The docker-compose up command fails on the healthcheck, with message being:
balessan#balessan-laptop:~/workspace/servers/ocean-dbs$ docker-compose up
Starting dbs_mariadb ...
ocean-dbs_dbs_1 is up-to-date
Starting dbs_mariadb ... done
ERROR: for dbs_filecoin Container "84e98cb80c06" is unhealthy.
ERROR: Encountered errors while bringing up the project.
When I access the container using a basic: docker exec -it dbs_mariadb bash command, and check mysqladmin or try to login, I get the following:
root#84e98cb80c06:/# mariadb --user=test --password=pass --silent --execute \"SELECT 1;\"
ERROR 1045 (28000): Access denied for user 'test'#'localhost' (using password: YES)
bash: ": command not found
root#84e98cb80c06:/# mysqladmin status
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'#'localhost' (using password: NO)'
I also inspected the container status itself and it says basically the same:

I am starting to feel stupid so, any help really appreciated !
