docker - 无法使用 podman 将图像推送到私有注册表

Question

尝试将图像推送到我们的私有港口注册表时出现以下错误

Error: Error copying image to the remote destination: Error reading blob sha256:f4e89ac0ce76ce2e69a371e66d372a1d67ce04707527634e4af782da63002b34: error creating overlay mount to /var/lib/containers/storage/overlay/7641274dd045465a42646537e46f0b30dcd5ef391af628af295d6eaa6de7ed81/merged: device or resource busy

CI 在 Jenkins 中运行在 Fedora 30 操作的节点上，我们buildah用于构建镜像，然后podman将其推送到私有注册表。

buildah bud --format=docker--tag ${DOCKER_REGISTRY}/name .

podman push ${DOCKER_REGISTRY}/name

的输出podman info --debug

快速说明 - 坦率地说，我不是这方面的专家，但即使只是向哪个方向提出建议也会非常有帮助。
