Fablo is a tool to generate the Hyperledger Fabric blockchain network and run it on Docker. It's main goal is to provide a super-easy start with Hyperledger Fabric. It has a declarative approach - a whole network is described in a single file. Right now only the Docker environment is supported and we want add support for Kubertnetes Operators.

Outcomes:
- Fablo is able to generate scripts and config files needed for kubernetes deployment
Timeline:
| Week | Deliverables | Status |
|---|
| June 1 - June 19 | - Onboarding and documentation exercises
- Get high level understanding of Fablo codebase
- Read Documentation for hyperledger fabric operator
- Environment Setup
| Done |
| June 20 - June 30 | - Use https://github.com/hyperledger-labs/hlf-operator to set up a simple network on k8s. Network should contain:
- two organizations (Orderer, Org1)
- one Orderer named orderer0.orderer.example.com
- two peers peer0.org1.example.com, peer1.org1.example.com both using LevelDb
- one channel `my-channel1` that joins both peer
- one chaincode `chaincode1` installed on `my-channel1` (we can provide sample one)
- Try to do the setup as a separate script, independent of Fablo generated files. We will connect them later.
- Try to list every component that Hyperledger offers (peers, orderers, ca's) and read about them. (we can provide useful links)
| Done |
July 1 - July 19 | - Rewrite Fablo target scripts for the simplest network on Kubernetes operators (CAs, Orderers, Peers)
- Learning part (by Mentor): Certificates. How they are used in Hyperledger, why they are so important, how they are implemented in k8s operators
| done |
| July 20 - July 31 | - Rewrite Fablo target scripts for the simplest network on Kubernetes operators (channels, chaincodes)
- Learning part (by Mentor): How do we test Fablo using GitHub actions
| done |
| August 1 - August 19 | - Prepare templates for created scripts, similar to current templates for Docker
| done |
| August 20 - August 31 | - Write snapshot tests for templates for k8s
|
|
| Septemeber 1 - September 19 | - Add and test validation rules (for instance: TLS is not supported for k8s)
|
|
| October 1 - October 19 | - Investigate the possibility to support Fablo's advanced feat

Learning part (by Mentor): Certificates. How they are used in Hyperledger, why they are so important, how they are implemented in k8s operators ures:- Orderer sharding
- Chaincode upgrade
- Snapshot/restore
- Fablo REST
- Channel query scripts
| done |
| October 19 - October 31 | - Investigate the possibility to support multi-tenant deployments (different clusters for orgs)
| done |
| November 1 - November 12 | - Verify all Fablo commands are properly supported: `./fablo k8s generate|start|stop|up|down|chaincode|...`
| done |
