Ghost Pro

Build me a self-hosted Ghost site to replace Ghost Pro. Requirements: - Do not write a CMS. Deploy the open-source Ghost itself on my VPS with Docker Compose: ghost and MySQL 8 containers, named volumes for content and the database. - Caddy in front for HTTPS on my domain with automatic certificates; Ghost bound to localhost so only Caddy is exposed. - Newsletter and transactional email via Mailgun, creds flowing from .env into the compose file, plus a checklist of the SPF/DKIM/DMARC DNS records. - Memberships and paid subscriptions wired to Stripe keys in .env, test mode first. - Nightly backup cron: mysqldump plus a tar of the content volume into ./backups/, keep 14, with a written restore procedure tested once for real. - An update.sh that pulls new images and restarts, with a note to read Ghost release notes before major-version jumps. - My content on my server; no third-party analytics added. - Out of scope: building a custom theme from scratch (start from the default theme) and any custom blog engine code. - README: DNS records, first-run admin setup, and the honest warning that upgrades and email deliverability are now my job, that is the trade.
