- Docker Compose, Docker File, Docker Stack, Swarm
Docker Compose (Docker Stack)
image: Specify the image to start the container from. Can either be a repository/tag or a partial image ID.
If the image does not exist, Compose attempts to pull it, unless you have also specified build, in which case it builds it using the specified options and tags it with the specified tag.
deploy: (resource limits) This only takes effect when deploying to a swarm with docker stack deploy, and is ignored by docker-compose up and docker-compose run.
depends_on: Express dependency between services. Service dependencies cause the following behaviors:
networks: Networks to join, referencing entries under the top-level networks key.
ports: (Port mapping) Either specify both ports (HOST:CONTAINER), or just the container port (an ephemeral host port is chosen).
environment: Environment variables with only a key are resolved to their values on the machine Compose is running on, which can be helpful for secret or host-specific values.
environment:
– SHOW=true
– SESSION_SECRET
volumes: bind mount, named volume
When you use a bind mount, a file or directory on the host machine is mounted into a container. The file or directory is referenced by its absolute path on the host machine. By contrast, when you use a volume, a new directory is created within Docker’s storage directory on the host machine, and Docker manages that directory’s contents. Volumes have several advantages over bind mounts.
The source of the mount. For bind mounts, this is the path to the file or directory on the Docker daemon host. May be specified as source or src.
The destination takes as its value the path where the file or directory is mounted in the container. May be specified as destination, dst, or target.
logging: The default driver json-file, has options to limit the amount of logs stored. To do this, use a key-value pair for maximum storage size and maximum number of files:
options:
max-size: “200k”
max-file: “10”
The example shown above would store log files until they reach a max-size of 200kB, and then rotate them. As logs grow beyond the max limits, older log files are removed to allow storage of new logs.
