-h, --help Print usage
-l, --log-level=info Set the logging level
--tls Use TLS; implied by --tlsverify
--tlscacert=~/.docker/ca.pem Trust certs signed only by this CA
--tlscert=~/.docker/cert.pem Path to TLS certificate file
--tlskey=~/.docker/key.pem Path to TLS key file
--tlsverify Use TLS and verify the remote
-v, --version Print version information and quit

Run 'docker COMMAND --help' for more information on a command.
docker-compose --help Define and run multi-container applications with Docker. Usage: docker-compose [options] [COMMAND] [ARGS...] docker-compose -h|--help Options: -f, --file FILE Specify an alternate compose file (default: docker-compose.yml) -p, --project-name NAME Specify an alternate project name (default: directory name) --verbose Show more output -v, --version Print version and exit Commands: build Build or rebuild services help Get help on a command kill Kill containers logs View output from containers port Print the public port for a port binding ps List containers pull Pulls service images restart Restart services rm Remove stopped containers run Run a one-off command scale Set number of containers for a service start Start services stop Stop services up Create and start containers migrate-to-labels Recreate containers to add labels
Déploiement d'un conteneur
docker pull mesoscloud/zookeeper
docker pull ansi/mosquitto
List containers
docker ps -a
List images
docker image
Exec commands
docker exec dockertp_nodered_1 ps docker exec dockertp_nodered_1 ls /
Définition de votre conteneur
- Dockerfile Reference https://docs.docker.com/engine/reference/builder/
- Best Practices https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/
TODO bridge Node.js MQTT --> InfluxDB
docker login docker push donsez/mqtt2influxdb:0.1
Docker Compose
Déploiement d'une composition
Créer le descripteur suivant pour cet stack IoT : docker-compose.yml
mongodb:
build: ./build/mongodb
volumes:
- /var/lib/docker/mongo/mongodb:/data/db
command: mongod --smallfiles
ports:
- "27017:27017"
mosquitto:
image: ansi/mosquitto
ports:
- "1883:1883"
nodered:
image: cpswan/node-red
volumes:
- /var/lib/docker/node-red/:/root/.node-red/
ports:
- "1880:1880"
links:
- mongodb
- mosquitto
Exécuter
docker-compose build docker-compose up
Test de la composition
Depuis un autre terminal de la machine qui exécute le conteneur Docker (ou depuis une autre machine)
docker ps -a docker images python -m webbrowser -t "http://localhost:1880"
