根因分析

Docker BuildKit 缓存导出失败，因为引用的缓存层丢失或损坏，通常是由于并发构建覆盖了相同的缓存或缓存上传不完整。

English

Docker BuildKit cache export fails because the referenced cache layer is missing or corrupted, often due to concurrent builds overwriting the same cache or incomplete cache uploads.

解决方案

  1. Invalidate the specific cache key by adding a unique build argument: docker build --build-arg BUILDKIT_INLINE_CACHE=1 --cache-from type=registry,ref=mycache --cache-to type=registry,ref=mycache,mode=max .
  2. Use a unique cache tag per build (e.g., cache-<commit-sha>) to avoid collision: docker build --cache-from type=registry,ref=myrepo/cache:${GITHUB_SHA} --cache-to type=registry,ref=myrepo/cache:${GITHUB_SHA} .
  3. Clear the remote cache entirely: docker buildx rm mybuilder; docker buildx create --use --driver-opt network=host; then rebuild with fresh cache export.

无效尝试

常见但无效的做法:

  1. Rebuilding the entire Docker image without cache (--no-cache) 50% 失败

    While this bypasses the cache key error, it defeats the purpose of caching and significantly increases build time; the underlying cache corruption is not fixed.

  2. Manually deleting all Docker cache directories on the runner 80% 失败

    Cache may be stored externally (e.g., on a registry or S3); local deletion doesn't fix remote cache corruption.

  3. Increasing the build timeout 95% 失败

    The error is not timeout-related; it's a cache integrity issue.
