ci-actions/deploy-static-site

deploy-static-site

Builds a Nix flake site, uploads a tarball to S3, and deploys it via Nomad using a shared static-server container image. Content is fetched from S3 at container startup — nothing is baked into the image.

Usage

- uses: https://git.toph.so/toph/ci-actions/deploy-static-site@main
  with:
    domain: example.com
  env:
    NOMAD_TOKEN: ${{ secrets.NOMAD_TOKEN }}
    AWS_ACCESS_KEY_ID: ${{ secrets.S3_ACCESS_KEY }}
    AWS_SECRET_ACCESS_KEY: ${{ secrets.S3_SECRET_KEY }}

Inputs

Input	Required	Default	Description
domain	yes	—	Domain the site is served at (e.g. toph.so)
flake-output	no	default	Flake output to build (e.g. docs)
nomad-addr	no	http://172.17.0.1:4646	Nomad API address
server-image	no	registry.toph.so/static-server:latest	OCI image for the static server
datacenter	no	contabo	Nomad datacenter
s3-endpoint	no	https://s3.toph.so	S3 endpoint URL
s3-bucket	no	nix-cache	S3 bucket for site tarballs
smoke-test	no	true	Run a smoke test after deploy

Environment Variables

Variable	Required	Description
NOMAD_TOKEN	yes	Nomad ACL token with deploy access to static-sites namespace
AWS_ACCESS_KEY_ID	yes	S3 access key
AWS_SECRET_ACCESS_KEY	yes	S3 secret key
NIX_SIGNING_KEY	no	If set, signs and pushes the Nix closure to the S3 binary cache (speeds up future builds)

Infrastructure Requirements

• registry.toph.so/static-server:latest must be pushed (see images/flake.nix and the build-static-server workflow)
• S3 bucket (nix-cache by default) must exist and be writable with the supplied credentials
• Nomad namespace static-sites is created automatically on first deploy

Site Flake Requirements

The site repo's flake must expose a package output that produces a directory of static files:

packages.x86_64-linux.default = # derivation whose $out contains static files

Use site-lib from this repo to set this up with minimal boilerplate:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    site-lib = {
      url = "git+https://git.toph.so/toph/ci-actions?dir=site-lib";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, site-lib }:
    site-lib.lib.mkSite {
      inherit self nixpkgs;
      src = ./.;
      installPhase = ''
        mkdir -p $out
        cp -r dist/. $out/
      '';
    };
}
