My Kuberentes Command Reference

This is my Kubernetes reference page. Most are commands that I don't want to forget, links to credits where due.

Get detailed cluster information

kubectl cluster-info dump

Get list of Kubernetes node IP addresses

kubectl get nodes -o jsonpath='{ $.items[*].status.addresses[?(@.type=="InternalIP")].address }'

Notes on Network Interfaces in Linux/Unix systems

Network Interface Notes

Beginning in Systemd v197, network interfaces assigned by systemd/udev are "predicatble";

Names are now based on;

  • Index numbers for on-board devices (eno1)
  • PCI-ehotplug slot index numbers (ens1)
  • Physical/geographical location of hardware connector (enp2s0)
  • MAC address (enx78e7d1ea46da)
  • Classic, unpredictable kernel-native naming (eth0)

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.) 
    

    2. 



git clone --bare git@github.com:usi-systems/easytrace.git
