Description

We are wrapping up the support for using Docker images and rFaaS (#10). However, we only use DockerHub, which has multiple restrictions - throttling and network latency. We want to locally deploy a Docker registry.

  • Add scripts for deploying the Docker registry and generating JSON configuration.
  • Add configuration of Docker registry in the rFaaS executor manager configuration.
  • Add polling Docker images on container allocation in the execution manager - only when the image is not present already.
  • Support registry credentials.

Contributor guide

Research direction
Read the rFaaS codebase to understand how Docker images are pulled and used. Then, implement the deployment script for a local registry and update the executor manager configuration to use it. Follow the checklist in the issue.
