Fabric Network Operator

• A tool to launch fabric network on kubernetes cluster or on a local machine using Docker. This tool creates the network based on a network specification file, and also creates connection profiles for each peer organization, which can be used by any client. It also can use its own testclient to generate channelTx transaction files, and perform fabric operations defined as "actions" in a test input file, such as creating channels, joining peers to a channel, anchor peer updates, installing, upgrading and instantiating chaincodes, and performing invokes and queries, migrating a network from kafka to etcdraft, checking the health of peers and orderers, and upgrading the network. This uses ytt https://github.com/k14s/ytt/blob/master/README.md to generate all necessary configuration files and a go program to launch fabric network

Prerequisites

• Go 1.14 or later
• Node 1.12.0 or later (for SDK interactions)
• Java 8 or later (if using Java chaincode)
• Docker
• Docker-Compose
• Curl and Make

Usage

Supported input arguments for operator are:

-a (action) string
       Set action(up, down, create, join, anchorpeer, install, instantiate, upgrade,
	   invoke, query, createChannelTxn, migrate, health) (default is up)
-i (input) string
       Network spec (or) Test input file path (Required)
-k (kubeconfig) string
       Kube config file path (If omitted, then use local network)

• -a is used to set type of action to be performed. It takes all the above actions as the values. Default value is up. #####Actions that uses network input file up To launch a fabric network. down To take down a network createChannelTxn To create channelTx for specified number of channels migrate To migrate a network to etcdraft health To perform health check on peers and orderers upgradeNetwork To upgrade an existing fabric network to latest version #####Actions that uses test input file create To create a channel join To join peers to a channel anchorpeer To perform anchor peer update install To install a chaincode instantiate To instantiate a chaincode upgrade To upgrade a chaincode invoke To perform invokes by sending the traffic to a fabric network query To perform queries on a fabric network

• -i is used to pass the absolute or relative file path for a network input file. It is required to launch/remove fabric network. Instructions for creating a networkSpec can be found here networkInput.md

• -k is used to pass the absolute or relative file path to a kube config file of kubernetes cluster. If -k is not specified in the command line, the operator will launch the fabric network locally using docker-compose

Examples

Fabric Network

To launch fabric network in kubernetes cluster, need kube config file for cluster and network input file go run main.go -i <path/to/network spec file> -k <path/to/kube config file> -a up or go run main.go -i <path/to/network spec file> -k <path/to/kube config file> To take down the launched fabric network from the above go run main.go -i <path/to/network spec file> -k <path/to/kube config file> -a down

To verify if fabric network is launched successfully or not in kubernetes cluster: export KUBECONFIG=<path/to/kube config file> kubectl get pods - To display list of pods running in kubernetes cluster kubectl get services - To display list of services created in kubernetes cluster

To launch fabric network locally using network input file go run main.go -i <path/to/network spec file> -a up or go run main.go -i <path/to/network spec file>

To take down launched fabric network locally go run main.go -i <path/to/network spec file> -a down

To verify if fabric network is launched successfully or not locally: docker ps -a

Fabric Operations

• To perform any action specified in the table above(for both the local network and the network launched in the kubernetes), use the below command go run main.go -i <path/to/test input file> -a <action>
• To upgrade a local fabric network, use the below command go run main.go -i <path/to/network spec file> -a upgradeNetwork To upgrade a fabric network launched using kubernetes, use the below command go run main.go -i <path/to/network spec file> -k <path/to kube config file> -a upgradeNetwork

E2E Example Locally With Docker

    make pre-reqs
    cd tools/operator
    go install .
    operator -i ../../regression/testdata/smoke-network-spec.yml -a up
    operator -i ../../regression/testdata/smoke-test-input.yml -a create
    operator -i ../../regression/testdata/smoke-test-input.yml -a join
    operator -i ../../regression/testdata/smoke-test-input.yml -a anchorpeer
    operator -i ../../regression/testdata/smoke-test-input.yml -a install
    operator -i ../../regression/testdata/smoke-test-input.yml -a instantiate
    operator -i ../../regression/testdata/smoke-test-input.yml -a invoke
    operator -i ../../regression/testdata/smoke-test-input.yml -a query
    operator -i ../../regression/testdata/smoke-test-input.yml -a upgrade
    operator -i ../../regression/testdata/smoke-test-input.yml -a invoke
    operator -i ../../regression/testdata/smoke-test-input.yml -a query
    operator -i ../../regression/testdata/smoke-network-spec.yml -a down

###Note: While you can compile the operator tool with cd tools/operator && go build . during development you can call the commands directly to compile your code on each invocation, i.e., go run main.go ...
