astartectl

Command line utility to manage Astarte

Installation

astartectl requires at least Go 1.17.

Using homebrew

If you are using homebrew on your system, you can install astartectl out of its tap:

brew tap astarte-platform/astarte
brew update
brew install astartectl

Using binaries from Github Release

You can download latest astartectl binaries for all platforms from GitHub Releases.

Move the binaries to your $PATH folder or set your $PATH to the folder where astartectl is run from.

Configuration

astartectl works with a context-based configuration. If you are familiar with how kubectl works, you'll find most of its concepts in astartectl configuration system. There are two main entities in astartectl configuration: cluster and context.

A cluster represents an Astarte Cluster. It might contain housekeeping credentials, but most of all it should bear the API URLs necessary to interact with the cluster. astartectl config clusters allows you to manipulate available clusters.

A context represents a configuration for astartectl, which references a cluster and, optionally an Astarte Realm. A context with no realm associated is meant to interact with Housekeeping (for, e.g., creating a Realm). astartectl config contexts allows you to manipulate available clusters.

Active context

At any time, when invoking astartectl without any further configuration options, the active context will be used. There is only one context available at a time, which can be queried by issuing astartectl config current-context. The context can be changed at any time using astartectl config set-current-context.

Fetching context information

In most cases, if you have access to the Kubernetes Cluster hosting your Astarte Cluster, you will be able to automatically build the cluster entry in the configuration. This can be done through the astartectl cluster instances get-cluster-config command, which creates a cluster entry based on the Astarte instance installed on the Kubernetes cluster referenced by your current kubectl context, if any.

In the same fashion, creating a new Realm automatically creates a new configuration context, if a private key and all necessary information are provided.
