Musings on cloud, devops & infrastructure as code

August 4, 2022

I believe most of us who works with Azure have felt the frustration of managing virtual networks as they grow in complexity. It’s easy to make mistakes when configuring peering and route tables and end up spending too much time running queries in Network Watcher to figure out what’s going on. Azure Virtual Network Manager aims to make this a lot easier and let us configure both Hub-Spoke and Mesh networks, as well as central management of security rules for all virtual networks.

As this new service is still in preview, there is no support for using the AzureRM provider in Terraform to configure it, but by using the AzAPI we can get up and running without diving into scripty shenanigans that breaks or otherwise declarative approach to infrastructure as code

Recently I spent a few (too many) hours to rebuild my personal website. It still use Hugo and Tailwind CSS, but I have changed hosting from using a storage account in Azure to using Azure Static Web Apps. The change has brought along some limitations, but it has also made the build pipeline a lot easier.

When I’m at home I have setup a Raspberry Pi to run Pi-hole and block pesky advertising.

But. I am not always at home. I also bring my Macbook to work, customers, airports & hotels. I didn’t want to clutter up my system and install Pi-hole natively, so instead I used Docker

I recently got a request from one of our customers who have an ERP system where they experience slowness due to high load the first monday and tuesday of every month. They wanted us to implement a scheduled scaling of the machine. As this is a single VM we could only scale up/down by changing the VM Size. The drawback is that this requires a reboot, but as long as you’re aware of the necessary downtime and setup your schedules outside office hours this can be solved easily with Azure Automation

My ISP does not give me a static IP. It doesn’t change often, but in the rare case that it has changed I never discover it before I actually need it.

So. I wanted a very simple way of auto-updating the home.example.com record. I didn’t want to bother with a thirdparty client from something like dyndns (and I didn’t want to pay for anything).

As I use Cloudflare as dns service for all domains I own I could just use their API and solve it with a oneliner, but doing it with Ansible is more readable
