containerPort property
The port number on the container that is bound to the user-specified or automatically assigned host port.
If you are using containers in a task with the awsvpc or
host network mode, exposed ports should be specified using
containerPort.
If you are using containers in a task with the bridge network
mode and 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 hostPort. Port mappings that are automatically
assigned in this way do not count toward the 100 reserved ports limit of a
container instance.
Implementation
