Prerequisites by use case

The validatorctl binary serves multiple purposes, therefore the system requirements vary based on how you intend to use it. See requirements by use case below.

Direct rule evaluation

None! Just install the validatorctl binary and get started with validatorctl rules check.

Installing validator on an existing kubernetes cluster

• Helm v3.14.0+
• Kubectl v1.24.10+

Installing validator into an ephemeral kind cluster

If you execute validator install without a KUBECONFIG set you'll be given the option to create and use a local kind cluster. Additional prerequisites are required in that case.

• Docker v24.0.6+ / Podman v5+
• Helm v3.14.0+
• Kind v0.20.0+
• Kubectl v1.24.10+

Setup

Binary Installation

You can download the validatorctl binary you require directly from the releases page or via curl. For instance, the v0.0.1 darwin binary can be installed and run like this:

curl -L -O https://github.com/validator-labs/validatorctl/releases/download/v0.0.1/validator-darwin-arm64
chmod +x validator-darwin-arm64
sudo mv validator-darwin-arm64 /usr/local/bin/validator
validator help

Building from Source

To build validatorctl from source, you'll need to ensure you're running go1.22.4. You can then build validatorctl and run it with the following commands:

make build
./bin/validator help

Usage

validatorctl provides several commands for managing validator plugins. Below are some common commands:

• Install validator and plugins in a cluster, and apply validation rules with the validator install --apply command.
• Describe validation results with the validator describe command.
• Re-configure validator plugins after they've been installed with the validator upgrade command.
• Uninstall the validator and all plugins with the validator uninstall command.
• Directly invoke validation rules with the validator rules check command.

Refer to Command Reference on the documentation site to learn more about each command. You can also issue the validator help command to learn more about the available commands.
