Installing a Specific FLECS Core Version

🎯 This guide is for advanced users who need to install a particular version of the FLECS Core and WebApp components.

📚 Introduction

While standard FLECS Core installations fetch the latest stable version, there are cases where developers or specialists may require a specific version – for example, to test compatibility, replicate an environment, or evaluate a pre-release feature.

This guide explains how to install a specific version of FLECS Core and the FLECS WebApp using FILiP (FLECS Installer for Linux Platforms).

If you are looking to install the latest standard version of FLECS Core, please refer to the guide:

Installing FLECS Core

🛠️ Prerequisites

Before beginning the installation, make sure you meet the following requirements:

• A compatible Linux device (Debian/Ubuntu/Yocto-based, AMD64 or ARM)

• Terminal access (SSH or connected keyboard/display)

• Internet connectivity for downloading the installer

🧪 Step-by-Step Installation of a Specific Version

Step 1: Run the Installation Command

To install a specific version of FLECS Core and WebApp, execute the following command in your terminal:

curl -fsSL install.flecs.tech | bash -s -- --core-version v3.6.2-hedgehog --webapp-version v3.6.0-hedgehog

Replace v3.6.2-hedgehog and v3.6.0-hedgehog with the versions you need.

You can find available versions here: 👉 https://github.com/FLECS-Technologies/flecs-public/releases 👉 https://github.com/FLECS-Technologies/flecs-webapp/releases

Step 2: Post-Installation Access

After installation, your device may reboot automatically. Access the FLECS WebApp by entering your device’s IP address or hostname into a browser:

http://<device-ip>

If the page doesn’t load, try appending :8080 or :8008 to the IP address.

🔐 Notes on Versioning

• The --core-version flag sets the runtime version of FLECS Core

• The --webapp-version flag sets the version of the FLECS WebApp.

• Use any valid release tag (e.g., v3.6.2-hedgehog). 👉 See all available versions at: https://github.com/FLECS-Technologies/flecs-public/releases https://github.com/FLECS-Technologies/flecs-webapp/releases

🧩 Troubleshooting

• If installation fails, check your network access and ensure Docker is not installed via Snap.

• For secure-only environments, use the --tls-only flag as an additional argument:

curl -fsSL install.flecs.tech | bash -s -- --core-version v3.6.2-hedgehog --webapp-version v3.6.0-hedgehog --tls-only

✅ Summary

Installing a specific version of FLECS Core is useful for development, testing, or compatibility purposes. FILiP makes it simple to pin the version you need using CLI arguments.
