fablo init [node] [rest] [dev]
Creates simple Fablo config in current directory with optional Node.js, chaincode and REST API and dev mode.
fablo generate [/path/to/fablo-config.json|yaml [/path/to/fablo/target]]
Generates network configuration files in the given directory. Default config file path is '\$(pwd)/fablo-config.json' or '\$(pwd)/fablo-config.yaml', default (and recommended) directory '\$(pwd)/fablo-target'.
fablo.sh up [/path/to/fablo-config.json|yaml]
fablo up [/path/to/fablo-config.json|yaml]
Starts the Hyperledger Fabric network for given Fablo configuration file, creates channels, installs and instantiates chaincodes. If there is no configuration, it will call 'generate' command for given config file.
fablo.sh <down | start | stop>
fablo <down | start | stop>
Downs, starts or stops the Hyperledger Fabric network for configuration in the current directory. This is similar to down, start and stop commands for Docker Compose.
fablo.sh reboot
fablo reset
Downs and ups the network. Network state is lost, but the configuration is kept intact.
fablo.sh prune
fablo prune
Downs the network and removes all generated files.
fablo.sh recreate [/path/to/fablo-config.json|yaml]
fablo recreate [/path/to/fablo-config.json|yaml]
Prunes and ups the network. Default config file path is '\$(pwd)/fablo-config.json' or '\$(pwd)/fablo-config.yaml'.
fablo.sh chaincode upgrade <chaincode-name> <version>
Upgrades and instantiates chaincode on all relevant peers. Chaincode directory is specified in Fablo config file.
fablo chaincodes install
Installs all chaincodes on relevant peers. Chaincode directory is specified in Fablo config file.
fablo chaincode install <chaincode-name> <version>
Installs chaincode on all relevant peers. Chaincode directory is specified in Fablo config file.
fablo chaincode upgrade <chaincode-name> <version>
Upgrades chaincode on all relevant peers. Chaincode directory is specified in Fablo config file.
fablo.sh channel --help
fablo channel --help
To list available channel query options which can be executed on running network.
fablo.sh use [version]
fablo snapshot <target-snapshot-path>
Creates a snapshot of the network in target path. The snapshot contains all network state, including transactions and identities.
fablo restore <source-snapshot-path>
Restores the network from a snapshot.
fablo use [version]
Updates this Fablo script to specified version. Prints all versions if no version parameter is provided.
fablo.sh <help | --help>
fablo <help | --help>
Prints the manual.
fablo.sh version [--verbose | -v]
fablo version [--verbose | -v]
Prints current Fablo version, with optional details."
