Frequently asked questions

How do I install Checkend without internet?

Export Docker images on a connected machine using `docker save`, transfer via approved media (USB, DVD), and import with `docker load` on the air-gapped system.

How do I get updates?

Follow the same process: download new images on a connected system, verify checksums, transfer via secure media, and deploy. We provide SHA256 checksums for verification.

Do notifications work offline?

Email notifications work with an internal mail server. Webhooks work with internal endpoints. External services (Slack, Discord) require network access.
