🚀 Casper NCTL 2 Docker

Casper NCTL 2 Docker provides containerized environments for running Casper NCTL (Node Control Tool) versions 1.x and 2.x. This setup supports different branches and configurations for stable, development, and version-specific releases of Casper Node and Client.

---

⚙️ What is this repository for?

This repository contains Docker images and Docker Compose services that simplify the process of running the Casper network's NCTL (Node Control Tool). NCTL is a tool used for managing Casper testnets. The images are configured to work with different branches and versions, including stable, development, and version-specific releases.

---

Key Features:

• Stable Version: Uses Casper Node 1.5.8 and Casper Client 2.0.0 for a stable environment.

• 2.0 Version: Uses the 2.0.0-rc9 release candidate for the Casper Node, v3.0.1 for the Client, and v1.0.3 for the Sidecar.

• Development Version: Tracks the latest development versions of Casper Node, Client, and Sidecar.

---

🚀 Usage

You can choose between stable, dev, or 2.0. If no profile is specified, stable is used by default.
