There was no CD: pushing to main deployed nothing, and deploys were a manual
copy onto the server. This adds the missing half.
- .github/workflows/deploy.yml - build, upload to a per-commit release
directory, swap the symlink atomically, reload nginx, verify over HTTP.
The swap only happens after the upload is verified to contain index.html,
so a failed deploy leaves the previous release serving.
- scripts/deploy/server-setup.sh - idempotent one-time provisioning: nginx,
certbot, ufw, and a key-only deploy user whose sole sudo right is
"systemctl reload nginx".
- scripts/deploy/add-domain.sh - per-domain server block plus TLS issuance,
run once a domain's A record resolves to the server.
- docs/DEPLOYMENT.md - setup order, required CI secrets, rollback, limits.
Also adds .gitattributes: the shell scripts were being checked out with CRLF
endings, which makes bash fail on the shebang line on Linux.
Host keys are pinned via DEPLOY_KNOWN_HOSTS rather than trusted on first use.
No credentials are committed; all four deploy secrets are supplied by CI.
