The BlockChain is a distributed database that maintains a continuously-growing list of ordered records called blocks. This technology underlying Bitcoin and other cryptocurrencies. It is a public ledger of all Bitcoin transaction. These blocks are added in a chronological order. In order to deploy a blockchain application, you need a distributed Hyperledger blockchain on your choice of infrastructure (on-premise or cloud). In this article, we will deploy a Hyperledger Fabric cluster using Kubernetes.
Prerequisites for BlockChain Application Deployment
To follow this guide you need a system with working Kubernetes cluster on it. We will use Fabric which is an implementation of blockchain technology written in Golang so go version go1.6.2 or above is required. Before proceeding further let’s have a look on Hyperledger Fabric.
The Hyperledger Project
Hyperledger is an open source project with collaborative effort created to advance blockchain technology. It helps in cross-industry distributed ledgers which support transaction system, property transaction, and other services.
The Fabric is an implementation of blockchain technology. It provides a modular architecture allowing pluggable implementations of the various function.
Hyperledger Kubernetes Replication Controller
We will launch hyperledger on kubernetes as a Replication Controller it will ensure us the high - availability of hyperledger pods. Create a file named membersrvc-rc.yml.
After that ChainCode console will display the message “Received REGISTERED, ready for invocations” which shows that ChainCode is ready for use.
Running Rest API
To log in with the help of REST API, send a POST request to the /registrar endpoint, with the enrollmentID and enrollmentPW. These parameters are listed in the eca.users section of the membersrvc.yaml file. REST Request:
You can also track the events on the console also.
Summarizing BlockChain Application Deployment
BlockChains can support the creation of new, more efficient business processes. Now as you understand the basic fundamentals of BlockChain Technology, you need to decide whether BlockChain fits your needs or not. There will be a rush to develop new decentralized apps so as to enable the decentralized world that we are moving towards. Considering this fact, Business Leaders need to learn a new vocabulary around crypto-related frameworks. Developers need to learn how to write decentralized apps that are enabled by BlockChain Technology. And End Users need to learn how to create or use smart contracts, e.g. as depicted via the Mist browser vision (Ethereum), which is a mix of marketplace discovery, management dashboard, and creation platform, all-in-one.
