Project ECS task resource stack

Browse source 
This projects the basic AWS::ECS::TaskDefinition CloudFormation template
type as a stack.  It also maps a bunch of schema types using fictitious
syntax, since we don't yet support this (see marapongo/mu#9).  On to that next...

of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision

don't specify a value, AWS CloudFormation generates a family name.

images in the Docker Hub registry or specify other repositories (`repository-url/image:tag`).

the allocated memory, the container is terminated.

units with other containers on the instance by using the same ratio as their allocated CPU units.
optional: true
disableNetworking:
type: bool
description: Indicates whether networking is disabled within the container.
optional: true
dnsSearchDomains:
type: string[]
description: A list of DNS search domains that are provided to the container. The domain names that the DNS
logic looks up when a process attempts to access a bare unqualified hostname.
optional: true
dnsServers:
type: string[]
description: A list of DNS servers that Amazon ECS provides to the container.
optional: true
dockerLabels:
type: string
spattern: ".+:.+"
description: A key-value map of labels for the container.
optional: true
dockerSecurityOptions:
type: string[]
description: A list of custom labels for SELinux and AppArmor multi-level security systems.
optional: true
entryPoint:
type: string[]
description: The `ENTRYPOINT` value to pass to the container.
optional: true
environment:
type: map[string]string
description: The environment variables to pass to the container.
optional: true
essential:
type: bool
description: Indicates whether the task stops if this container fails. If you specify `true` and the
container fails, all other containers in the task stop. If you specify `false` and the container fails,
none of the other containers in the task is affected. This value is `true` by default.
optional: true
extraHosts:
type: hostEntry[]
description: A list of hostnames and IP address mappings to append to the `/etc/hosts` file.
optional: true
hostname:
type: string
description: The name that Docker will use for the container's hostname.
optional: true
links:
type: string[]
description: The name of another container to connect to. With links, containers can communicate with each
other without using port mappings.
optional: true
logConfiguration:
type: logConfiguration
description: Configures a custom log driver for the container.
optional: true
mountPoints:
type: mountPoint[]
description: The mount points for data volumes in the container.
optional: true
portMappings:
type: portMap[]
description: A mapping of the container port to a host port. Port mappings enable containers to access ports
on the host container instance to send or receive traffic.
optional: true
privileged:
type: bool
description: Indicates whether the container is given full access to the host container instance.
optional: true
readonlyRootFilesystem:
type: bool
description: Indicates whether the container's root file system is mounted as read only.
optional: true
ulimits:
type: ulimit[]
description: A list of ulimits to set in the container. The ulimits set constraints on how much resources a
container can consume so that it doesn't deplete all available resources on the host.
optional: true

optional: true
volumesFrom:

description: The working directory in the container in which to run commands.
optional: true
host:
sourcePath:
type: string
description: The data volume path on the host container instance. If you don't specify this parameter, the
Docker daemon assigns a path for you, but the data volume might not persist after the associated
container stops running. If you do specify a path, the data volume persists at that location on the host
container instance until you manually delete it.
optional: true
hostEntry:

description: The hostname to use in the `/etc/hosts` file.
ipAddress:
type: string
description: The IP address to use in the `/etc/hosts` file.

optional: true
portMap:
containerPort:
type: integer
description: The port number on the container bound to the host port.
hostPort:
type: integer
description: The host port number on the container instance that you want to reserve for your container. You
can specify a non-reserved host port for your container port mapping, omit the host port, or set the
host port to `0`. If you specify a container port but no host port, your container host port is assigned
automatically. Don't specify a host port in the `49153` to `65535` port range; these ports are reserved
for automatic assignment. Other reserved ports include `22` for SSH, `2375` and `2376` for Docker, and
`51678` for the Amazon EC2 Container Service container agent. Don't specify a host port that is being
used for a task—that port is reserved while the task is running.
