How It's Made Pt2 or Hugo in S3 and CloudFront

Posted on


In Part 1 I built my architecture using Route53, S3 and CloudFront. This would suit pretty much any static site, but I chose to use Hugo. Why? I hadn’t used it before…

Bringing it all together

Go back and read the first part for how to get yourself a place where you can put static HTML in S3, and then serve it over a CDN with HTTPS through CloudFront - all without using the GUI!

Then have a look at Hugo’s Quick Start guide.

Now we just need a way to take the blog posts and put them in the bucket!

I’m a big fan of Makefiles, so I decided that was the way to go. You can see it with everything else in my GitHub Repo, but it looks something like:

	cd ./blog && hugo -t hugo_theme_pickles

deploy: build
	aws s3 sync ./blog/public/ s3://blog-martinlee-org/

	cd ./blog && hugo server -t hugo_theme_pickles -w -D

	aws cloudfront create-invalidation --distribution-id E734L0F2WYJ6 --paths /posts/* / /index.html

Worth noting - the indentation must be tabs, not spaces.

Now, I can run make dev to see the post on my local machine while I’m making a draft, and then make deploy to put that on the internet. I could in future extend it to implement a make draft to put draft posts somewhere for people to proof-read.

It’s worth understanding CloudFront’s Cache Invalidation. AWS provide 1000 free invalidations per month, but after that they cost $0.005 per invalidation path. I did briefly consider putting invalidations in the deploy stage, but decided I’d rather it was a more conscious decision.

The Future

So far it’s working nicely, and I can put blog posts on the internet practically as fast as I can write Markdown 1. I like not having to use a CMS and I love the speed of a static site. I could make it a bit more flexible in future by integrating a CI/CD system like CircleCI - allowing me to simply do a Git commit from anywhere, so that’ll probably feature in the near future.
