[All DCA Questions]

Can this set of commands identify the published port(s) for a container?

Solution: `docker network inspect', `docker port'

AYes

BNo

Show Suggested Answer

Suggested Answer: A

Yes, the docker port command can be used to identify the published ports for a running container. It shows the mapping between the host ports and the container's exposed ports. The docker network inspect command can also provide information about the network settings of the container, including port mappings. However, it's important to note that docker network inspect requires the network's name or ID as an argument, not the container's. Therefore, to get the network details of a specific container, you would first need to identify the network the container is connected to. These commands, when used appropriately, can help you identify the published ports for a container.

Wait, can it really do that? I thought it was just for networks.

Easy peasy! The bond is trading at a yield above the coupon rate, so the clean price will be below par. I'll go with option B.
