DPHAT: Data Plane Health Assessment Tool For Cloud Networking Technology
a project by rtidwell
Updated almost 6 years ago. 1 hackers ♥️. 2 followers.

A common challenge for OpenStack and K8S deployments is debugging the network when things go awry. The aim of DPHAT is to provide operators of cloud infrastructure with tooling that can analyze the environment and supply the following:

  • Feedback that the environment is in a healthy operational state
  • Identification of and guidance about where something in the network fabric is broken
  • Guidance on remediation steps
  • A pluggable interface to enable support for various cloud platforms, their respective networking backends, and any hardware devices (ie switches/routers) present in the deployment
  • RESTful API, CLI, and UI

This involves:

  • Gathering information from any relevant SDN controller, representing the network topology for the cloud, and developing an algorithm for analyzing the topology
  • Probing of VM's and containers via ARP, ICMP (ping), port scan, ofproto trace, etc. to asses forwarding and security policy instantiation
  • Reading pod / compute node state and identifying missing namespaces, tap devices, iptables chains, etc.
  • Building a database of remediation actions that can be correlated with issues flagged by DPHAT

If you want to help alleviate the headache of debugging networking issues in the cloud, let's work together!

    kubectl clone: Seamlessly Clone Kubernetes Resources Across Multiple Rancher Clusters and Projects by dpunia

    Description

    kubectl clone is a kubectl plugin that empowers users to clone Kubernetes resources across multiple clusters and projects managed by Rancher. It simplifies the process of duplicating resources from one cluster to another or within different namespaces and projects, with optional on-the-fly modifications. This tool enhances multi-cluster resource management, making it invaluable for environments where Rancher orchestrates numerous Kubernetes clusters.

    Goals

    1. Seamless Multi-Cluster Cloning
      • Clone Kubernetes resources across clusters/projects with one command.
      • Simplifies management, reduces operational effort.

    Resources

    1. Rancher & Kubernetes Docs

      • Rancher API, Cluster Management, Kubernetes client libraries.

    2. Development Tools

      • Kubectl plugin docs, Go programming resources.

    Building and Installing the Plugin

    1. Set Environment Variables: Export the Rancher URL and API token:
    • export RANCHER_URL="https://rancher.example.com"
    • export RANCHER_TOKEN="token-xxxxx:xxxxxxxxxxxxxxxxxxxx"
    1. Build the Plugin: Compile the Go program:
    • go build -o kubectl-clone ./pkg/
    1. Install the Plugin: Move the executable to a directory in your PATH:
    • mv kubectl-clone /usr/local/bin/

    Ensure the file is executable:

    • chmod +x /usr/local/bin/kubectl-clone
    1. Verify the Plugin Installation: Test the plugin by running:
    • kubectl clone --help

    You should see the usage information for the kubectl-clone plugin.

    Usage Examples

    1. Clone a Deployment from One Cluster to Another:
    • kubectl clone --source-cluster c-abc123 --type deployment --name nginx-deployment --target-cluster c-def456 --new-name nginx-deployment-clone
    1. Clone a Service into Another Namespace and Modify Labels:

    Harvester Packer Plugin by mrohrich

    Description

    Hashicorp Packer is an automation tool that allows automatic customized VM image builds - assuming the user has a virtualization tool at their disposal. To make use of Harvester as such a virtualization tool a plugin for Packer needs to be written. With this plugin users could make use of their Harvester cluster to build customized VM images, something they likely want to do if they have a Harvester cluster.

    Goals

    Write a Packer plugin bridging the gap between Harvester and Packer. Users should be able to create customized VM images using Packer and Harvester with no need to utilize another virtualization platform.

    Rancher/k8s Trouble-Maker by tonyhansen

    Project Description

    When studying for my RHCSA, I found trouble-maker, which is a program that breaks a Linux OS and requires you to fix it. I want to create something similar for Rancher/k8s that can allow for troubleshooting an unknown environment.

    Goal for this Hackweek

    Create a basic framework for creating Rancher/k8s cluster lab environments as needed for the Break/Fix Create at least 5 modules that can be applied to the cluster and require troubleshooting

    Multi-pod, autoscalable Elixir application in Kubernetes using K8s resources by socon

    Description

    Elixir / Erlang use their own solutions to create clusters that work together. Kubernetes provide its own orchestration. Due to the nature of the BEAM, it looks a very promising technology for applications that run in Kubernetes and requite to be always on, specifically if they are created as web pages using Phoenix.

    Goals

    • Investigate and provide solutions that work in Phoenix LiveView using Kubernetes resources, so a multi-pod application can be used
    • Provide an end to end example that creates and deploy a container from source code.

    Remote control for Adam Audio active monitor speakers by dmach

    Description

    I own a pair of Adam Audio A7V active studio monitor speakers. They have ethernet connectors that allow changing their settings remotely using the A Control software. From Windows :-( I couldn't find any open source alternative for Linux besides AES70.js library.

    Goals

    • Create a command-line tool for controlling the speakers.
    • Python is the language of choice.
    • Implement only a simple tool with the desired functionality rather than a full coverage of AES70 standard.
