Obtaining mapped port from within docker container

Question

I'm using Cloudfront and ECS to run tasks within AWS. I map my tasks to random host ports using the following command:

      PortMappings:
        - HostPort: 0
          ContainerPort: 8080

I need to know, within the container, the DN of the host and the random port the task was mapped to. How can I achieve this?

Answer 1

According to the documentation ,

After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description of a selected task in the Amazon ECS console, or the networkBindings section [of] DescribeTasks responses.
