Assigning Static IP Addresses in WSL2

WSL2 uses Hyper-V for networking. The WSL2 network settings are ephemeral and configured on demand when any WSL2 instance is first started in a Windows session. The configuration is reset on each Windows restart and the IP addresses change each time. The Windows host creates a hidden switch named "WSL" and a network adapter named "WSL" (appears as "vEthernet (WSL)" in the "Network Connections" panel). The Ubuntu instance creates a corresponding network interface named "eth0".

Assigning static IP addresses to the network interfaces on the Windows host or the WSL2 Ubuntu instance enables support for the following scenarios:

BGP

Document outling software architecture for integration of FRR into OVN for OCP and OSP. This is written in markdown for eventually addition as an enhancement proposal.

BGP Architectural Components

As we discuss use cases, we can start to distill them down to the building blocks necessary to achieve them. Some of these may be shared across multiple products.

BGP Speaker

A component capable of publishing routes only, called out separately as this may be simpler than (b) and (c)

Create a systemd template unit for Envoy proxies with Consul

This brief tutorial will walk through the process of creating a systemd template unit file for starting Envoy sidecars for use with Consul service mesh.

Template unit files allow systemd to address multiple units from a single configuration file. You can call a systemd template unit file using a special format to use this feature:

Config files

To configure Zsh for your user’s session, you can use the following files:

$ZDOTDIR/.zshenv
$ZDOTDIR/.zprofile
$ZDOTDIR/.zshrc
$ZDOTDIR/.zlogin
$ZDOTDIR/.zlogout

By default, Zsh will try to find the user’s configuration files in the $HOME directory. You can change it by setting the environment variable $ZDOTDIR.

Migrating from Ubuntu on WSL to ArchLinux on WSL2

Obsolete notice

This document was created back in 2020 and might not be actual nowadays. It is not supported anymore, so use thise information at your own risk.

Upgrading to WSL 2

Download WSL2 Kernel
run wsl --set-default-version 2 in windows command line, so that all future WSL machine will use WSL2.
