MixBytes Tank

Requirements

• Python3
• Terraform 0.11.13
• Terraform-Inventory v0.8

Installation

Terraform & Terraform-Inventory

Can be done with tank/install-terraform.sh.

Optional: create virtualenv

Optionally, create and activate virtualenv

sudo apt-get install -y python3-virtualenv
python3 -m virtualenv -p python3 venv

After virtualenv creation and each time after opening a terminal, activate virtualenv to work with the tank:

. venv/bin/activate

Tank

pip3 install mixbytes-tank

Usage

1. Configure the user config

Configure ~/.tank.yml. The example can be found at docs/config.yml.example.

Please configure at least one cloud provider. The essential steps are:

• providing (and possibly creating) a key pair;
• registering the public key with your cloud provider if needed;
• specifying a cloud provider access token or credentials.

2. Create or get a tank testcase

The example can be found at docs/testcase_example.yml.

3. Start a tank run

tank cluster deploy <testcase file>

4. Login into the monitoring

Locate the newly created instance which name ends with -monitoring in your cloud, find the instance ip. Open in browser http://{monitoring ip}:3000/dashboards, username and password are tank.

The dashboards can always be found at http://{monitoring ip}:3000/dashboards

5. List current active runs

There can be multiple tank runs at the same time. List and brief information can be seen via:

tank cluster list

6. Create synthetic load

tank cluster bench <run id> [--tps N] [--total-tx N]

<run id> - id of the run

--tps - global transactions per second generation rate,

--total-tx - how many transactions to send (total).

7. Shutdown and remove the cluster

tank cluster destroy <run id>

Hacking

Alternative binding version

Bindings can be configured at ~/.tank/bindings.yml (by default the predefined binding config is copied and used).
