docker-compose [-f...] [options] [COMMAND] [ARGS...]
DOCKER-COMPOSE BUILD
Commande : docker-compose build
Build or rebuild services.
Services are built once and then tagged as `project_service`,
e.g. `composetest_db`. If you change a service's `Dockerfile` or the
contents of its build directory, you can run `docker-compose build` to rebuild it.
Usage: build [options] [--build-arg key=val...] [SERVICE...]
Options:
--compress Compress the build context using gzip.
--force-rm Always remove intermediate containers.
--no-cache Do not use cache when building the image.
--pull Always attempt to pull a newer version of the image.
-m, --memory MEM Sets memory limit for the build container.
--build-arg key=val Set build-time variables for services.
Construire ou reconstruire les images des services dont le Dockerfile a été modifié :
Si un Dockerfile est modifié, un docker-compose up ne le prendra pas en compte, il faut effectuer un rebuild du service correspondant (ou de tous les services).
Le cache sera utilisé jusqu’à la première ligne modifiée.
docker-compose build [SERVICE...]
ex :
$ docker-compose build
Construire ou reconstruire les images avec les dernières versions des images de base :
docker-compose build --pull [SERVICE...]
ex :
$ docker-compose build --pull
Construire ou reconstruire les images sans utiliser le cache :
docker-compose build --no-cache [SERVICE...]
ex :
$ docker-compose build --no-cache
DOCKER-COMPOSE CONFIG
Commande : docker-compose config
Validate and view the Compose file.
Usage: config [options]
Options:
--resolve-image-digests Pin image tags to digests.
-q, --quiet Only validate the configuration, don't print
anything.
--services Print the service names, one per line.
--volumes Print the volume names, one per line.
Pour plus d’informations sur la génération de configurations avec docker-compose, voir l’article suivant :
Docker – Mini-tutos
Vérifier la configuration et la syntaxe du fichier Docker Compose :
docker-compose config
ex :
$ docker-compose config
ERROR: yaml.scanner.ScannerError: while scanning a simple key
in "./docker-compose.yml", line 2, column 1
could not find expected ':'
in "./docker-compose.yml", line 3, column 1
Vérifier la configuration et la syntaxe du fichier Docker Compose silencieusement par le code retour :
docker-compose config -q
ex :
$ docker-compose config -q $ echo $? 0
Lister les services définis dans le fichier Docker Compose :
docker-compose config --services
Equivaut à :
docker-compose ps --services
ex :
$ docker-compose config --services
vote
result
redis
worker
db
Lister les volumes définis dans le fichier Docker Compose :
docker-compose config --services
ex :
$ docker-compose config --volumes
db-data
DOCKER-COMPOSE DOWN
Commande : docker-compose down
Stops containers and removes containers, networks, volumes, and images
created by `up`.
By default, the only things removed are:
- Containers for services defined in the Compose file
- Networks defined in the `networks` section of the Compose file
- The default network, if one is used
Networks and volumes defined as `external` are never removed.
Usage: down [options]
Options:
--rmi type Remove images. Type must be one of:
'all': Remove all images used by any service.
'local': Remove only images that don't have a
custom tag set by the `image` field.
-v, --volumes Remove named volumes declared in the `volumes`
section of the Compose file and anonymous volumes
attached to containers.
--remove-orphans Remove containers for services not defined in the
Compose file
-t, --timeout TIMEOUT Specify a shutdown timeout in seconds.
(default: 10)
Arrêter les services, supprimer les containers et les réseaux de l’application :
Contrairement à la commande docker-compose stop, les containers seront non seulement arrêtés mais également supprimés.
Les réseaux définis dans le fichier docker-compose.yml seront également supprimés.

DOCKER-COMPOSE UP
Commande : docker-compose up
Builds, (re)creates, starts, and attaches to containers for a service.
Unless they are already running, this command also starts any linked services.
The `docker-compose up` command aggregates the output of each container. When
the command exits, all containers are stopped. Running `docker-compose up -d`
starts the containers in the background and leaves them running.
If there are existing containers for a service, and the service's configuration
or image was changed after the container's creation, `docker-compose up` picks
up the changes by stopping and recreating the containers (preserving mounted
volumes). To prevent Compose from picking up changes, use the `--no-recreate`
flag.
If you want to force Compose to stop and recreate all containers, use the
`--force-recreate` flag.
Usage: up [options] [--scale SERVICE=NUM...] [SERVICE...]
Options:
-d, --detach Detached mode: Run containers in the background,
print new container names. Incompatible with
--abort-on-container-exit.
--no-color Produce monochrome output.
--quiet-pull Pull without printing progress information
--no-deps Don't start linked services.
--force-recreate Recreate containers even if their configuration
and image haven't changed.
--always-recreate-deps Recreate dependent containers.
Incompatible with --no-recreate.
--no-recreate If containers already exist, don't recreate
them. Incompatible with --force-recreate and -V.
--no-build Don't build an image, even if it's missing.
--no-start Don't start the services after creating them.
--build Build images before starting containers.
--abort-on-container-exit Stops all containers if any container was
stopped. Incompatible with -d.
-t, --timeout TIMEOUT Use this timeout in seconds for container
shutdown when attached or when containers are
already running. (default: 10)
-V, --renew-anon-volumes Recreate anonymous volumes instead of retrieving
data from the previous containers.
--remove-orphans Remove containers for services not defined
in the Compose file.
--exit-code-from SERVICE Return the exit code of the selected service
container. Implies --abort-on-container-exit.
--scale SERVICE=NUM Scale SERVICE to NUM instances. Overrides the
`scale` setting in the Compose file if present.
Démarrer une application ou des services en particulier :
Si aucun service n'est spécifié, ils seront tous démarrés dans l'ordre défini par les dépendances.
Si un service est spécifié, seul lui sera démarré, sauf s'il possède un ou plusieurs dépendances, auxquels cas ces dernières seront démarrées au préalable.
Sans l'option -d, ils seront démarrés au premier-plan.
Avec l'option -d, ils seront démarrés en arrière-plan (mode detach).
Avec l'option --no-deps, les dépendances ne sont pas démarrées au préalable.

Démarrer une application tout en reconstruisant les images (directive build) :
docker-compose up [options] --build [SERVICE...]
ex :
$ docker-compose up -d --build
Définir le fichier Docker Compose à utiliser :
Par défaut, Docker Compose utilise le fichier docker-compose.yml situé dans le répertoire courant.
On peut toutefois spécifier un fichier alternatif avec l'option -f (--file).
docker-compose -f filename [options] [SERVICE...]
ex :
$ docker-compose -f docker-compose-simple.yml up -d
Définir le working directory à utiliser :
Par défaut, Docker Compose utilise le répertoire courant comme répertoire de travail.
On peut toutefois spécifier un répertoire de travail alternatif avec l'option --project-directory.
docker-compose --project-directory directory [options] [SERVICE...]
ex :
$ docker-compose --project-directory compose-sample-1/ --file compose-sample-1/docker-compose.yml up -d
Scaler un service :
Si le service utilise l'instruction container_name pour nommer le container correspondant, il ne pourra pas être scalé : plusieurs containers ne peuvent pas avoir le même nom
Si le service expose un port particulier, il ne pourra pas être scalé : plusieurs containers ne peuvent pas utiliser le même port de la machine hôte.
docker-compose up [options] --scale service=N [SERVICE...]
ex :
$ docker-compose up -d --scale simulator=3
