CNF ESB Project

ESB is used to insulate the data-exchanging between client apps and server apps.

There are two projects in this solution:

1. cnf.esb.web
   This is the main project of ESB, in fact, we just need build and deploy this project into a docker container.
   In the “data” folder of this project, “esb.db” file is a database (SQLite) which is used to store all configurations and executing logs.
2. cnf.esb.testApi
   This is a fake server app that is used for testing ESB features. You needn’t deploy it on production.

Main features of ESB

1. Management

• To register a client app as a “consumer” in ESB;
• To register an API of server app as a “service” in ESB;
• To create an “instance” which allow a “consumer” to invoke a “service”;
• To view executing logs which are recorded when consomer invoked service.

  2. Deamon

• Caller developers can use https://[esb_host:port]/api/help/[instance_id] to display the contract of which consumer invoke service and the response from service;
• In client app, POST data to https://[esb_host:port]/api/invoke/[instance_id] to cosume the API.

Deploy with docker

1. pull docker from Docker hub: rensting/cnf.esb:{version#} (the latest version tag is v1.1)
2. create a local folder, and copy the esb.db SQLite database file into it.
3. run the docker with attaching the local fold as volume by option: -v {local_folder}:/app/data
4. run the docker with port mapping by option: -p {host_port}:443 (https) or :80 (http)

run docker simple:

docker run -d -v /home/data:/app/data -p 80:80 rensting/cnf.esb:v1.1
