# Kubernetes Test Network
|
|
|
|
This project re-establishes the Hyperledger [test-network](../test-network) as a _cloud native_ application.
|
|
|
|
### Objectives:
|
|
|
|
- Provide a simple, _one click_ activity for running the Fabric test network.
|
|
- Provide a reference guide for deploying _production-style_ networks on Kubernetes.
|
|
- Provide a _cloud ready_ platform for developing chaincode, Gateway, and blockchain apps.
|
|
- Provide a Kube supplement to the Fabric [CA Operations and Deployment](https://hyperledger-fabric-ca.readthedocs.io/en/latest/deployguide/ca-deploy.html) guides.
|
|
- Support a transition to [Chaincode as a Service](https://hyperledger-fabric.readthedocs.io/en/latest/cc_service.html).
|
|
- Support a transition from the Internal, Docker daemon to [External Chaincode](https://hyperledger-fabric.readthedocs.io/en/latest/cc_launcher.html) builders.
|
|
- Run on any Kube.
|
|
|
|
_Fabric, Ahoy!_
|
|
|
|
|
|
## Prerequisites
|
|
|
|
- [kubectl](https://kubernetes.io/docs/tasks/tools/)
|
|
- [Docker](https://www.docker.com)
|
|
- K8s: [kind](https://kind.sigs.k8s.io/docs/user/quick-start/#installation) or [Rancher / k3s](https://rancherdesktop.io)
|
|
- [jq](https://stedolan.github.io/jq/)
|
|
- [envsubst](https://www.gnu.org/software/gettext/manual/html_node/envsubst-Invocation.html) (`brew install gettext` on OSX)
|
|
|
|
|
|
## Quickstart
|
|
|
|
Create a KIND Kubernetes:
|
|
```shell
|
|
./network kind
|
|
```
|
|
For environments running [Rancher k3s](docs/KUBERNETES.md#rancher-desktop-and-k3s):
|
|
```shell
|
|
export TEST_NETWORK_CLUSTER_RUNTIME=k3s
|
|
|
|
./network cluster-init
|
|
```
|
|
|
|
Fabric services are exposed by Kubernetes Ingress at the fictitious DNS domain `*.local.fabric`. Add the
|
|
following aliases to your /etc/hosts file:
|
|
```
|
|
127.0.0.1 org0-ca.local.fabric
|
|
127.0.0.1 org1-ca.local.fabric
|
|
127.0.0.1 org2-ca.local.fabric
|
|
127.0.0.1 org0-orderer1.local.fabric
|
|
127.0.0.1 org0-orderer2.local.fabric
|
|
127.0.0.1 org0-orderer3.local.fabric
|
|
127.0.0.1 org1-peer1.local.fabric
|
|
127.0.0.1 org1-peer2.local.fabric
|
|
127.0.0.1 org2-peer1.local.fabric
|
|
127.0.0.1 org2-peer2.local.fabric
|
|
```
|
|
|
|
Launch the network, create a channel, and deploy the [basic-asset-transfer](../asset-transfer-basic) smart contract:
|
|
```shell
|
|
./network up
|
|
./network channel create
|
|
|
|
./network chaincode deploy asset-transfer-basic basic_1.0 $PWD/../asset-transfer-basic/chaincode-java
|
|
```
|
|
|
|
Invoke and query chaincode:
|
|
```shell
|
|
./network chaincode invoke asset-transfer-basic '{"Args":["CreateAsset","1","blue","35","tom","1000"]}'
|
|
./network chaincode query asset-transfer-basic '{"Args":["ReadAsset","1"]}'
|
|
```
|
|
|
|
Access the blockchain with a [REST API](https://github.com/hyperledger/fabric-samples/tree/main/asset-transfer-basic/rest-api-typescript):
|
|
```shell
|
|
./network rest-easy
|
|
```
|
|
|
|
Tear down the test network:
|
|
```shell
|
|
./network down
|
|
```
|
|
|
|
Tear down the cluster:
|
|
```shell
|
|
./network unkind
|
|
```
