About ttl.sh

ttl.sh is an anonymous, ephemeral container registry intended for CI workflows, where images are only needed for a short time. It is built on zot, an off-the-shelf OCI registry, and fronted by Nginx with TLS.

The repository contains the Ansible configuration for the host (Nginx with TLS, Docker and the Compose deployment), the Next.js marketing site served at ttl.sh, and the Docker Compose stack that runs the web and zot services. Nginx proxies the site to the web container and the registry API to zot, with the catalog endpoint blocked. Zot is configured to store blobs in an S3-compatible bucket.

The README notes that it configures an existing server rather than provisioning infrastructure, and that tag expiry is handled separately and is not yet wired up in the repository. Deployment instructions are in DEPLOYING.md, and pushes to the deploy branch trigger a GitHub Actions workflow. It is Apache-2.0 licensed and run as a public service at ttl.sh.
