Exonum CIS Dynamic Services Launcher

Project description

Exonum CIS Dynamic Service Launcher

A tool to send deploy&init requests into the Exonum CIS blockchain.

Usage

usage: exonum_launcher_cis [-h] -i INPUT [-r RUNTIMES [RUNTIMES ...]]
                       [--runtime-parsers RUNTIME_PARSERS [RUNTIME_PARSERS ...]]
                       [--instance-parsers INSTANCE_PARSERS [INSTANCE_PARSERS ...]]

Exonum service launcher

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT, --input INPUT
                        A path to yaml input for service initialization
  -r RUNTIMES [RUNTIMES ...], --runtimes RUNTIMES [RUNTIMES ...]
                        Additional runtimes, e.g. `--runtimes java=1 python=2
                        wasm=3`
  --runtime-parsers RUNTIME_PARSERS [RUNTIME_PARSERS ...]
                        Runtime spec parsers, e.g. `--runtime-parsers
                        python=your_module.YourRuntimeSpecLoader` Values will
                        be imported and treated like SpecLoader, so ensure
                        that module with loader is in `sys.path`.
  --instance-parsers INSTANCE_PARSERS [INSTANCE_PARSERS ...]
                        Instance spec parsers, e.g. `--runtime-parsers
                        python=your_module.YourInstanceSpecLoader` Values will
                        be imported and treated like InstanceSpecLoader, so
                        ensure that module with loader is in `sys.path`.

So, if you want to run exonum-launcher_cis with Rust runtime only and without custom artifact spec loaders, you can just use:

python3 -m exonum_launcher_cis -i sample.yml

If you want to use exonum-launcher with Python runtime and Python runtime spec loader, the command will be:

python3 -m exonum_launcher_cis --runtimes python=2 --runtime-parsers python=exonum_launcher.runtimes.python.PythonSpecLoader -i sample.yml

Example of expected yaml file:

networks:
  - host: "127.0.0.1"
    ssl: false
    public-api-port: 8080
    private-api-port: 8081

deadline_height: 10000

artifacts:
  cryptocurrency:
    runtime: rust
    name: "exonum-cryptocurrency-advanced:0.12.0"

  # Example of artifact that should not be deployed
  example_artifact:
    runtime: rust
    name: "exonum-cryptocurrency-advanced:0.12.0"
    deploy: false

instances:
  xnm-token:
    artifact: cryptocurrency
    config: []
  nnm-token:
    artifact: "cryptocurrency"
    config: []
  some-instance:
    # Since we will not deploy `example_artifact`, it is assumed that it is already deployed
    artifact: "example_artifact"
    config:
      val_a: "123"
      val_b: 345

Important: if you have more than one validator in the network, ensure that connection data (networks section of the config) is specified for every validator.

Deploy&init process requires requests to be sent to each validator, so don't expect that transaction broadcast mechanism will work here.

Plugins

You can define custom runtimes and plugins in the config (so you won't have to provide them from command line):

runtimes:
  python: 2

plugins:
  runtime:
    python: "exonum_launcher_cis.runtimes.python.PythonSpecLoader"
  artifact: {}

See samples folder for more examples.
