Docusaurus v3 is out, but official docs are still lacking deployment to AWS as option.

Let me fix this and guide you how to create most secure and up to date approach with AWS S3 and Cloudfront.

tip

TL;DR final approach:

  • private S3 bucket without website static hosting enabled
  • Cloudfront distribution with Origin Access Control (OAC)
  • Cloudfront Function to handle redirects to index.html

You can skip development instructions and go to full samples source code available at https://github.com/ahanoff/how-to/tree/main/docusaurus-3-deployment-with-s3-and-cloudfront

Docusaurus is static website generator, so let's review options AWS offers us to serve it.

Worry-free AWS ACM certificate DNS validation with Pulumi

Quite often I need to create AWS ACM certificate and do DNS validation using Pulumi.

Pulumi aws.acm.CertificateValidation DNS example only show basic and naive implementation:

  • hardcoded single domain validation ¯_(ツ)_/¯
  • will fail if you try to validated wildcard and apex domain simultaneously
* creating Route 53 Record: InvalidChangeBatch: [Tried to create resource record set [name='_f22110437fea5500aa0f8bf286aed7c7.howto.ahanoff.dev.', type='CNAME'] but it already exists]

Today I'll show how to create validation that works for any domain

note
  • I will use howto.ahanoff.dev domain as example
  • I will use Pulumi with Typescript

I will create AWS ACM certificate with the following conditions:

  • multi domain certificate
  • validates wildcard domain: *.howto.ahanoff.dev
  • validates apex domain: howto.ahanoff.dev

ECS Task healtheck for Alpine-based containers

If you are working with AWS ECS, you might know about ECS task healthcheck. AWS documentation suggests to use curl in command:

[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]

I usually try to minimize container image size, thus my first choice for base image is Alpine.

Unfortunately, it doesn't come with curl installed out of the box. It only includes wget.
