      <description>同样是构建 Go 镜像，用 Dockerfile + BuildKit 要 2-3 分钟，用 ko 只需要 5-20 秒。差距来自 ko 不走 daemon、不写 tar、直接把 Go 编译产物塞进 OCI manifest。本文讲清楚这套 &amp;lsquo;Dockerfile-less&amp;rsquo; 构建到底怎么落地到生产，以及什么时候不该用它。</description>

      <title>BuildKit 缓存生产实战：从多阶段到远端 Registry Cache</title>

      <description>BuildKit 的缓存体系看似简单一行 &amp;ndash;cache-to，实际生产里坑极多：mode=max 在多架构下的 manifest 行为、registry 后端每层 0.3s 的验证开销、cache mount 在 &amp;ndash;cache-to=registry 下不被导出的限制、GHA 后端 10GB 上限……本文基于真实 CI 流水线的调优记录，给出一套可复制的生产配置。</description>
