Announcing Spegel v0.2.0
The focus of this release has been on cleaning up the codebase, increasing test coverage, and simplifying future extensions. A few minor, non-breaking bugs introduced in v0.1.0 have also been fixed. Beyond that, the two main improvements that matter to end users are: a new cleanup mechanism added to the Helm chart, and the introduction of prebuilt binary releases for Spegel. Cleanup of Mirror Configuration The lack of proper cleanup has been a major pain point for users testing or benchmarking Spegel. Previously, Spegel would write the containerd mirror configuration to the host, but would not remove it when the Helm chart was uninstalled. This left behind mirror settings pointing to a registry that no longer existed. The result varied, but typically added unwanted latency as containerd attempted to reach a mirror that would never respond. In clusters that regularly rotate nodes, this wasn’t an issue since new nodes wouldn’t have the stale configuration. Still, this was bad practice on Spegel’s part.

Announcing Spegel v0.1.0
Spegel’s journey began with its first commit in February 2023, sparked by a curiosity about OCI and Containerd, along with a challenge to explore alternative image distribution methods. In the two years since, it has evolved into a valuable tool for everyone from homelab enthusiasts to multinational corporations. Seeing the GitHub stars climb has been rewarding, a clear indicator that adoption is growing and people recognize its value.
