Install and upgrade
- Install the controllerInstall the controller with one command: requirements, what the installer does, how to log in and verify.
- Add nodesGet a command from the panel, run it on a new machine, approve it and the node comes up by itself; requirements, ports and FAQ.
- Online upgradesUpgrade the controller and nodes from the panel: pre-checks, staged and one-click upgrades, automatic rollback on failure.
- Uninstall and migrateUninstall nodes and the controller, keep or purge data, and migrate the controller to a new machine from a backup.
Sites
- Add a siteAdd a site with its domain and origin, get the CNAME target after saving; bulk add and common errors.
- Set up the CNAME recordPoint the domain at the address gocdn gives you with a CNAME at your DNS provider, and check that it works.
- HTTPS certificatesRequest a free certificate or upload your own, then turn on HTTPS, forced redirect, HTTP/2 and HTTP/3.
- Cache rulesUse cache rules to decide what is cached and for how long; by group or custom, and how to raise the hit ratio.
- Purge and prefetchAfter content changes, purge makes nodes drop old cache; prefetch pulls popular content to nodes ahead of time.
- Origin settingsSet the origin protocol and port, how several origins share traffic and their weights, and allow nodes through the origin firewall.
