| 3 | # step skips what exists. Run after scripts/setup-deployments.sh, then | |
| 4 | # deploy with scripts/deploy.sh (deployments, then pages). | |
| 5 | # | |
| 6 | # Custom domains are Cloudflare for SaaS custom hostnames on the apps' zone | |
| 7 | # (g1t.page). Turn Cloudflare for SaaS on for the zone first, in the | |
| 8 | # dashboard: SSL/TLS, Custom Hostnames. Until then the API answers with | |
| 9 | # codes 1404 or 1456, and g1t says custom domains are being switched on. | |
| 10 | # | |
| 11 | # This script: | |
| 12 | # 1. creates the g1t-domains KV namespace (hostname -> app) and writes its | |
| 13 | # id into services/deployments and services/pages wrangler.jsonc; | |
| 14 | # 2. adds the fallback origin's DNS record: domains.g1t.page, proxied | |
| 15 | # AAAA 100:: (what every custom domain points at); | |
| 16 | # 3. sets domains.g1t.page as the zone's custom hostname fallback origin. | |
| 17 | # | |
| 18 | # Steps 2 and 3 need CLOUDFLARE_EMAIL and CLOUDFLARE_API_KEY (a Global API | |
| 19 | # Key), or CLOUDFLARE_ZONE_TOKEN with DNS: Edit and SSL and Certificates: | |
| 20 | # Edit on the zone; otherwise it says what to do by hand. | |
| 21 | # | |
| 22 | # The deployments service's own token (its CLOUDFLARE_API_TOKEN secret) | |
| 23 | # also needs SSL and Certificates: Edit on the zone, to add custom | |
| 24 | # hostnames. Add that permission to the token in the dashboard. | |
