Be mindful of the high costs when running the Hyperledger Fabric network on Kubernetes and AWS; estimate expenses, apply mitigation strategies, monitor billing, and set a realistic budget.

Learn how domain names and DNS routing work, set up a domain and free SSL with Let's Encrypt, and route domain traffic to your network through a load balancer.

Master kops commands to delete clusters, edit ig nodes and ig masters, perform rolling updates, validate the cluster, and scale the network by adding nodes and updating configurations.

Install and configure the Ingress Nginx controller to route external DNS traffic into your Kubernetes cluster, terminate SSL, and route API service and web service with permanent redirects.

Create folders for production config, production transaction config, checking code, and bin files, then copy the chain code and scripts to storage and verify their presence.

Join channels, install and approve chaincodes, and test the network by running parallel commands, channel updates, and queries to validate cross-organization visibility.

Learn how to add a new organization to a Hyperledger Fabric 2.x network on Kubernetes/AWS, update configs, deploy peers, and install and test chaincode from a production environment.

Use the config transaction generator to derive the difference for a new org config and print the org definition into channels.json for insertion into the network configuration.

Learn to build a basic hybrid ledger network on Hyperledger Fabric by generating certificates with the crypto gen, configuring channel artifacts and genesis blocks, and deploying orderers, peers, and chaincode.

Start a solo hyperledger fabric orderer with docker-compose, using channel artifacts and crypto config to initialize the network. Mount MSP and artifacts, and verify genesis block and state.

Configure and start two org peers in Hyperledger Fabric, map ports, MSP, and TLS, and bootstrap gossip to enable peer communication with the order and each other.

Install and instantiate chaincode across peers, remove the bridge command and clean up cli containers, then write and query data to the ledger in a complete end-to-end fabric workflow.

Upgrade the chaincode on a Hyperledger Fabric network and add a query function to fetch data without adding blocks; install version 1, upgrade, and test via query.

Demonstrate querying all peers in Hyperledger Fabric to verify that they hold consistent data by using the same query function across peers and observing identical results.

learn the fundamentals to build and test a Hyperledger Fabric network by creating a Vue.js frontend, a Go backend, and dockerizing the projects for use in the network.

Add a delete route and a destroy function on the front-end, filtering by id and dispatching destroy, while preparing the API to remove the item from the server.

Containerize the front end with docker, npm build, and a multi-stage workflow, then serve via engine X or Apache and configure docker-compose for dev and production.

Build and push docker images by creating a docker file, tagging, and authenticating to Docker Hub. Run and test containers, including port binding, to verify the front end deployment.

Build a basic http server in go using gorilla mux, configure cors handlers, and wire a modular backend with router and server components for hyperledger services.

Create a modular router with route models, add home and status routes, and attach them with patterns and handlers; implement a static file server for a static directory.

Add a back-end users model, implement login and logout, and create CRUD routes, using Google's uuid package, bcrypt password hashing with salt, and ensure unique IDs before insertion.
