I’m a long time Linux user, and a big fan of Docker, Kubernetes, VMs, and containers.
While I love developing on Linux - I do sometimes find it frustrating that I don’t have the same level of access to the Microsoft suite on Linux.
A while ago I had to use a Windows laptop for a few days and tried out using WSL - so most of the time I’m in Linux - I didn’t entirely hate it so when it was time for an upgrade I decided to try the Windows route this time.
I’ve had my new machine for a little over a week now.
I’ve had a few problems with docker and firewalls and seem to get a “good enough” solution only to run into trouble again later having forgotten what I’ve done so far.
This is an attempt to make some notes and at least capture where I am up to.
TLDR
- Disable dockers Iptables
- Add some firewalld rules
- Watch out if the Docker interface changes

As web developers we are used to people mostly using teh websites we build in teh way intended.
It can be hard to get into the mindset not just of what can go wrong but how what we have built can be subverted.
There are a lot of tools available to those who want to attack our websites - and I think it is worth web developers having some familiarity with these.
The tools themselves are legal - but should only be used where you have permission.

I tried various install media, tried editing grub conf.
The best I could get was a screen saying

This turned out to be painful because the system has an old BIOS and while you can in theory install windows from a USB stick - doing so requires a newer system using UEFI
Linux installs fine from a USB stick so this caught me out.
It turns out the Windows installer works fine from an external DVD drive - but first you may have to buy some double layer DVDs because the image doesn’t quite fit on a normal one.
