        "description": "# MixBytes Tank [![master](https://travis-ci.org/mixbytes/tank.svg?branch=master)](https://travis-ci.org/mixbytes/tank)\n\nMixBytes Tank is a console tool which can set up a blockchain cluster in minutes in a cloud and bench it using various transaction loads.\nIt'll highlight blockchain problems and give insights into performance and stability of the technology.\n\nAt the moment, supported blockchains are [Haya](https://github.com/mixbytes/haya) and [Polkadot](https://polkadot.network).\n\nSetup - bench - dispose workflow is very similar to a test case, that is why configuration of such run is described in a declarative YAML file called \"testcase\".\n\nMore info can be found at:\n\n* [Guide](docs/guide/README.md)\n* [Cookbook](docs/cookbook/README.md)\n* Quick guide below\n\nContributions are welcomed!\n\nDiscuss in our chat: [https://t.me/MixBytes](https://t.me/MixBytes).\n\n\n# Quick guide\n\n## Requirements\n\n- Python3\n\n## Installation\n\n```shell\npip3 install mixbytes-tank\n```\n\nUse the `--pre` option to get the latest release candidate:\n\n```shell\npip3 install mixbytes-tank --pre\n```\n\n\n## Usage\n\n### 1. Configure the user config\n\nConfigure `~/.tank.yml`. The example can be found at [docs/config.yml.example](docs/config.yml.example).\n\nPlease configure at least one cloud provider. The essential steps are:\n* providing (and possibly creating) a key pair\n* registering a public key with your cloud provider (if needed)\n* specifying a cloud provider access token or credentials\n\n### 2. Create or get a tank testcase\n\nThe example can be found at [docs/testcase_example.yml](docs/testcase_example.yml).\n\n### 3. Start a tank run\n\n```shell\ntank cluster deploy <testcase file>\n```\n\nAs a result, the cluster instance listing will be printed along with the run id and the monitoring link.\n\n### 4. Log in to the monitoring\n\nOpen the monitoring link in your browser, type in 'tank' in the username and password fields.\nYou will see cluster metrics in the predefined dashboards.\n\n### 5. List current active runs\n\nThere can be multiple tank runs at the same time. The runs list and brief information about each run can be seen via: \n\n```shell\ntank cluster list\n```\n\n### 6. Create synthetic load\n\n```shell\ntank cluster bench <run id> <load profile js> [--tps N] [--total-tx N]\n```\n\n`<run id>` - run ID\n\n`<load profile js>` - a js file with a load profile: custom logic which creates transactions to be sent to the cluster\n\n`--tps` - total number of generated transactions per second,\n\n`--total-tx` - total number of transactions to be sent.\n\n### 7. Shutdown and remove the cluster\n\n```shell\ntank cluster destroy <run id>\n```\n\n\n# Development\n\n## Branching\n\nfeatures -> `develop` -> `master`.\n\n`master` is production-ready code.\n\n`develop` is expected-to-be production-ready code which is merged into master after thorough testing\n(so, no faulty code in `develop` pls).\n\n`develop` and `master` branches are permanent.\n\n\n",
