NixOS AMIs

Github Action that regularly uploads AMIs for release channels

Note

The files in ./modules are NOT being used yet and we are not building images from this repository yet. Instead we are uploading the AMIs from this Hydra job: https://hydra.nixos.org/job/nixos/release-23.11/nixos.amazonImage.x86_64-linux

Setting up account

Some steps need to be done manually to set up the account. This is a one time process. These are hard to automate with Terraform.

First opt in to all regions:

nix run .#enable-regions

You might get rate-limited so need to wait and rerun until all finish:

botocore.errorfactory.TooManyRequestsException: An error occurred (TooManyRequestsException) when calling the EnableRegion operation (reached max retries: 4): This request has exceeded the quota for 'Number of concurrent region-opt requests for an account'. Consider retrying the operation later once some requests have been completed.

Now wait until all regions are enabled. You can use:

aws account list-regions --region-opt-status-contains ENABLING

Then request a quota increase for the number of AMIs you want to publish. This will create support tickets in all regions. You can check the status of the tickets in the AWS console. It might take a few days for the tickets to be resolved.

nix run .#request-public-ami-quota-increase -- --desired-value 1000

Finally enable public AMIs:

nix run .#disable-image-block-public-access
