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:

Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!

Run Puppeteer inside termux

Assumptions

• You have termux installed and have sufficient permissions
• You have loggedin as root user
• You are okay with running Puppeteer inside a container (Alpine)

Gotchas

• There is no build of Google Chrome available for ARM at this moment, so using chromium instead.
• Installing chromium on Termux directly requires snap which is another big hurdle so alternively using alpine distro here.

Ramp up your Kubernetes development, CI-tooling or testing workflow by running multiple Kubernetes clusters on Ubuntu Linux with KVM and minikube.

In this tutorial we will combine the popular minikube tool with Linux's Kernel-based Virtual Machine (KVM) support. It is a great way to re-purpose an old machine that you found on eBay or have gathering gust under your desk. An Intel NUC would also make a great host for this tutorial if you want to buy some new hardware. Another popular angle is to use a bare metal host in the cloud and I've provided some details on that below.

We'll set up all the tooling so that you can build one or many single-node Kubernetes clusters and then deploy applications to them such as OpenFaaS using familiar tooling like helm. I'll then show you how to access the Kubernetes clusters from a remote machine such as your laptop.

Pre-reqs

• This tutorial uses Ubuntu 16.04 as a base installation, but other distributions are supported by KVM. You'll need to find out how to install
