Deploys Kafka, Mongodb and Kafka.

Mongo-express: http://localhost:8081 Sawtooth-explorer: http://localhost:8091 Sawtooth-rest-api: http://localhost:8008 PgAdmin: http://localhost:9095 user: a@a.com password: password123 Server Group 1/Minimally Defined Server/Databases/my_database

Code:

In ./app/ there are scripts to test sawtooth, kafka and mongo.

tp1 has the transaction procesor (similar to a smart contract). This transaction processor stores a value with a key like a map or hashtable.

Suggestions

Edit up.sh to only run the code that is required. Edit ./docker-compose/docker-compose.yaml so that only the required containers are run
