AkôFlow - Open Source Middleware for Containerized Scientific Workflows

AkôFlow is an open-source middleware for orchestrating and executing container-based scientific workflows across heterogeneous environments. It was originally developed within the e-Science Research Group at the Institute of Computing, Fluminense Federal University (UFF).

Although initially focused on Kubernetes-based workloads, AkôFlow has evolved to support general containerized execution across multiple infrastructures.

Software Requirements

• Operating System: Linux, macOS or WSL2 (Windows Subsystem for Linux)
• Docker: Install Docker
• kubectl: Install kubectl
• Kubernetes Cluster: One of the following:
  • Kind (local)
  • Docker Desktop Kubernetes (enable Kubernetes in settings)
  • Cloud providers (e.g., EKS, GKE, AKS)

Instalation

Run the following command to install AkôFlow:

curl -fsSL https://akoflow.com/run | bash

AkôFlow will be available at http://localhost:8080.

Academic Context

AkôFlow originated as a final undergraduate project and has since expanded with broader contributions and integrations. It continues to serve both academic and industrial workflow execution scenarios.
