docker desktop run automatically a container into an docker compose structure - docker

Question

Each time I start my docker desktop application into Windows 11 OS,
It launch automatically a container into a docker-compose structure.
But not the others containers into this docker-compose.
I dealing with a MariaDB container...
My Apache container and my PHP container not run automatically. Just MariaDB
This is my docker-compose.yml file :
version: '3'
services:
apache:
build: ./docker/apache
container_name: projectx_apache
tty: true
ports:
- '443:443'
depends_on:
- php
- mariadb
volumes:
- ./:/var/www/projectx/
php:
build: ./docker/php
container_name: projectx_php
tty: true
volumes:
- ./:/var/www/projectx/
mariadb:
build: ./docker/mariadb
container_name: projectx_mariadb
restart: always
tty: true
environment:
MYSQL_ROOT_PASSWORD: docker
MYSQL_DATABASE: projectx
MYSQL_USER: docker
MYSQL_PASSWORD: docker
ports:
- '3306:3306'
this is my Dockerfile for MariaDB container :
FROM mariadb:latest
ENV MYSQL_ROOT_PASSWORD docker
ENV MYSQL_DATABASE projectx
ENV MYSQL_USER root
ENV MYSQL_PASSWORD docker
RUN apt-get -y update
RUN apt-get -y install vim
EXPOSE 3310
CMD ["mysqld"]
And this is my log container when It start automatically :

Do you have an idea why this container start automatically ?

Answer 1

The reason for automatic start here is restart: always on MariaDB container,
It will start the container when the docker daemon restart. See
restart policy
