docker: Start all containers, rebuild if necessary.

docker

$ docker compose up --build

try on your machine

The docker-compose up --build command is used to build and start the containers defined in the docker-compose.yml file for a multi-container Docker application.

Here is a breakdown of the command:

docker-compose: This command is used to manage multi-container Docker applications using a YAML file called docker-compose.yml.
up: This option is used to create and start containers for all the services defined in the docker-compose.yml. It starts the containers in the foreground and shows the logs for each service.
--build: This option is used to build images before starting the containers. When you specify --build, it will check for any changes in the services' Dockerfiles and build new images if necessary. Without --build, it will use the existing images.

In summary, the docker-compose up --build command builds the required Docker images for the services defined in the docker-compose.yml file and then starts the containers for those services, displaying the logs in the console.
