There&rsquo;s a whole host of security, resiliency, and observability reasons to do so. But mostly, I think the reason is that adding complexity to my life seems to be my MO. In the last week or so, image pulls have been taking a long time. Harbor is backed by S3 on a very large, and very underpowered NAS so I didn&rsquo;t think <em>too</em> much about it&hellip; until I updated an application version and it was pulling a container for well over 20 minutes. The image is a Golang binary the entire image is 8 megabytes&hellip; something ain&rsquo;t right.</p>
