The Late Night Linux Family<p>Shane gives us an update on his janky Kubernetes homelab. The storage is under control with ZFS, he’s got a decent switch, and everything is in Git – so maybe it isn’t that janky anymore.</p><p><a href="https://hybridcloudshow.com/hcs36/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">hybridcloudshow.com/hcs36/</span><span class="invisible"></span></a></p><p><a href="https://mastodon.social/tags/podcast" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>podcast</span></a> <a href="https://mastodon.social/tags/cloud" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cloud</span></a> <a href="https://mastodon.social/tags/PlatformEngineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PlatformEngineering</span></a></p>
"Musty Bits" McGee<p>The new Kubernetes mount-an-OCI-artifact feature got me thinking about backups, layers, data locality, and deduplication via CAS.</p><p>Imagine using image layers as snapshots and pushing images as your application's data backup. Then by specifying latest* for the volume mount it would automatically come up with eagerly-cached, local data.</p><p>I don't think CAS helps our case for storage here as a layer-snapshot mapping isn't granular enough. Of course it's not like you'd want to redesign your Postgres paging configuration entirely around a better mapping to image layers but there's something there...</p><p>Registry-side you could do periodic compaction, archival, export etc.</p><p>OCI image layers are already limited though last time I checked. Nix maps derivations (think packages) to layers and neither OCI nor the tooling were designed for that kind of blowout. Could be tackled though.</p><p>*yes yes, anti pattern. Hold ur underwear a moment.</p><p><a href="https://eigenmagic.net/tags/OCI" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OCI</span></a> <a href="https://eigenmagic.net/tags/Containers" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Containers</span></a> <a href="https://eigenmagic.net/tags/Kubernetes" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Kubernetes</span></a> <a href="https://eigenmagic.net/tags/k8s" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>k8s</span></a> <a href="https://eigenmagic.net/tags/PlatformEngineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PlatformEngineering</span></a> <a href="https://eigenmagic.net/tags/DevOps" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DevOps</span></a> <a href="https://eigenmagic.net/tags/Cloud" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Cloud</span></a> <a href="https://eigenmagic.net/tags/Docker" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Docker</span></a></p>
