You can have nice things

I have come across a few things that are legitimately pleasant to use, so I thought I should collate them here to aid my aging memory. Dear reader, I am not attempting to copy Scott Hanselman’s tools list, I am stealing the concept.

Github Actions

Yea, not something revolutionary I just uncovered that you never heard of before, but still. It’s pretty great. Out of all the yet-another-yet-another-markup-language-configuration-file-to-configure-a-thing tools that exist that help you orchestrate builds, I personally find Github Actions the least weirdly magical and easy to live with, but then I’ve only tried CircleCI, Azure DevOps/TFS and TeamCity.

Pulumi – Infrastructure as code

Write your infrastructure code in C# using Pulumi.It supports Azure, AWS, Google Cloud and Kubernetes, but – as I’ve ranted about before, this shouldn’t be taken as a way to support multi-cloud, the object hierarchy is still very bespoke to each cloud provider. That said, you can mix and match providers in a stack, let’s say you have your DNS hosted in DNSimple but your cloud compute bits in Azure. You would be stuck doing a lot of bash scripting to make it work otherwise, but Pulumi lets you write one C# file that describes all of your infra, mostly.
You will recognise the feel of using it from chef, basically you write code that describes the infrastructure, but the actual construction isn’t happening in the code, first the description is made, the desired state is then compared to the actual running state, and adjustments are made. It is a thin wrapper over terraform, but it does what it says on the tin.

MinVer – automagic versioning for .NET Core

At some point you will write your build chain hack to populate some attributes on your Assembly to stamp a brand on a binary so you can display a version on your site that you can track back to a specific commit. The simplest way of doing this, without needing to change branching strategy or write custom code, is MinVer.

It literally browses through your commits to find your version tags and then increments that version with how many commits there are from that commit. It is what I dreamed would be out there when I started looking. It is genius.

A couple of gotchas: It relies – duh- on having access to the git history, so you need to remember to remove .git from your .dockerignore file, or else your dotnet publish inside docker build will fail to locate any version information. Obviously, unless you intended to release all versions of your source code in the docker image, make sure you have a staged docker build – this is the default in recent Visual Studio templates – but still. I encourage you in any case to mount your finished docker image using docker run -it --entrypoint sh imagename:tag to have a look that your docker image contains what you expect.

Also, in your GitHub Actions you will need to allow for a deeper fetch depth for your script to have enough data to calculate the version number, but that is mentioned in the documentation. I already used a tag prefix ‘v’ for my versions, so I had to add that to my project files. No problems, it just worked. Very impressed.
