A simple auction system implemented on a P2P network. Basic APIs are described in Auction Mechanism APIs.

• Create an auction with a certain end date and starting price.
• Check the status of an auction.
• Place a bid on an auction that has not ended yet

• Create an auction with a certain end date, starting price and a "Buy it Now" option.
• Buy an auction through the "Buy it now" option.
• Delete an ongoing auction with no bids.

Note: The "check" now gives new information due to the "Buy it Now" option.

The package src/main/java/edu/ds provides four Java classes:

• Auction, a class with all the information related to an auction.
• AuctionMechanism, an interface that defines the auction mechanism.
• AuctionMechanismImpl, an implementation of the AuctionMechanism interface.
• Terminal, a terminal that allow to interact with the auction system.

The package src/tes/java provides one JUnit class:

• AuctionMechanismTest, a Junit class with different test cases.

NOTE While doing tests through terminal be aware of date timezone.

Build your docker container:
docker build --no-cache -t auctionsystem .

Start the master peer, in interactive mode (-i) and with two (-e) environment variables:
docker run -i --name MASTER-PEER -e MASTERIP="127.0.0.1" -e ID=0 auctionsystem

,the MASTERIP envirnoment variable is the master peer ip address and the ID environment variable is the unique id of your peer. Rember you have to run the master peer using the ID=0.

When master is started check the ip address of your container:

• Check the docker : docker ps
• Check the IP address: docker inspect <container ID>

Now you can start your peers varying the unique peer "id":
docker run -i --name PEER-<id> -e MASTERIP=<IP ADDRESS> -e ID=<id> auctionsystem

Example:

docker run -i --name PEER-1 -e MASTERIP="172.17.0.2" -e ID=1 auctionsystem

The project has been implemented with:

• Java 8
• Apache Maven
• Eclipse IDE
• Tom p2p
• JUnit4
• Docker
