• Domains and proxyRouting with Traefik per server (nginx is legacy), TLS modes, the base domain, custom domains, redirects and a note on Cloudflare.
• Env vars and secretsHow powder stores environment variables encrypted, records who changed what, rolls back single keys and delivers values to containers.
• BackupsEncrypted Postgres backups to S3-compatible storage with retention, download, restore into a new database, and verify.
• Crons, uptime and logsScheduled jobs run by powder, how uptime checks pick a URL and when they alert, and where to find deploy logs.
