NAME

Paws::ECS::PortMapping

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::ECS::PortMapping object:

  $service_obj->Method(Att1 => { ContainerPort => $value, ..., Protocol => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::ECS::PortMapping object:

  $result = $service_obj->Method(...);
  $result->Att1->ContainerPort

DESCRIPTION

Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition. After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.

ATTRIBUTES

ContainerPort => Int

  The port number on the container that is bound to the user-specified or
automatically assigned host port. If you specify a container port and
not a host port, your container automatically receives a host port in
the ephemeral port range (for more information, see C<hostPort>). Port
mappings that are automatically assigned in this way do not count
toward the 100 reserved ports limit of a container instance.

HostPort => Int

  The port number on the container instance to reserve for your
container. You can specify a non-reserved host port for your container
port mapping, or you can omit the C<hostPort> (or set it to C<0>) while
specifying a C<containerPort> and your container automatically receives
a port in the ephemeral port range for your container instance
operating system and Docker version.

The default ephemeral port range is 49153 to 65535, and this range is used for Docker versions prior to 1.6.0. For Docker version 1.6.0 and later, the Docker daemon tries to read the ephemeral port range from /proc/sys/net/ipv4/ip_local_port_range; if this kernel parameter is unavailable, the default ephemeral port range is used. You should not attempt to specify a host port in the ephemeral port range, because these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678 and 51679. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released).The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output, and a container instance may have up to 100 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward the 100 reserved ports limit).

Protocol => Str

  The protocol used for the port mapping. Valid values are C<tcp> and
C<udp>. The default is C<tcp>.
