Permanent WSL DNS Fix (WSL 2.2.1+)

If you're encountering ping github.com failing inside WSL with a Temporary failure in name resolution, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.

This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf.

DNS tunneling is enabled by default in WSL version 2.2.1 and later, meaning that if you're still seeing DNS resolution issues, the first and most effective fix is simply to upgrade WSL. Upgrading WSL updates the WSL platform itself, but does not affect your installed Linux distributions, apps, or files.

To upgrade WSL, follow these steps,

OpenFaaS Cloud - Encrypted user secrets for Kubernetes

This Gist shows you how to make use of SealedSecrets in OpenFaaS Cloud. Your secrets can be encrypted with the public key of OpenFaaS Cloud meaning you can commit them to your public or private Git repo. Once deployed the cluster will decrypt them and attach them to your function(s).

Before starting you must install the kubeseal binary using the OpenFaaS Cloud CLI extensions:

One liner for deleting images from a v2 docker registry

Just plug in your own values for registry and repo/image name.

registry='localhost:5000'
name='my-image'
curl -v -sSL -X DELETE "http://${registry}/v2/${name}/manifests/$(
    curl -sSL -I \
        -H "Accept: application/vnd.docker.distribution.manifest.v2+json" \

Fedora - sudo dnf install pcsc-tools opensc ccid

ubuntu - sudo dnf install pcsc-tools opensc libccid

Find out where OpenSC has installed the pkcs11 module.

For OS X with binary installation this is typically in /Library/OpenSC/lib/. Homebrew users can use export OPENSC_LIBS=$(brew --prefix opensc)/lib

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:
