benschlueter/delegatio

Delegatio is a framework that can be used to create isolated remote environments on a local machine. It currently supports Libvirt for Infrastructure and Kubernetes for container management.

• I've worked / I am working with the following languages: Golang, C, C++, eBPF, VHDL, Python

delegatio's Issues

Wait until crio is ready

Sometimes the bootstrapper is faster than crio, resulting in a failed installation. Wait for crio-service to be ready before marking a node a ready.

Unittest

• provide better abstraction for the Kubernetes related code (i.e. create Interfaces)
• abstract QEMU c binding to make the code testable
• test the internal packages

Refactor the CLI

• switch to Cobra
• split create infra, install Kubernetes, and initialize Kubernetes into 3 cli subcommands
• generate config files for each subcommand

Libvirt image issues

Errors during bootstrap the qemu instaces through libvirt

Flaky ssh subpackage tests

Add Cloudprovider as Infrastructure Backend

• Add GCP
• Add Azure
