kubelet FailedSync 同步 pod 时出错，正在跳过：API 错误 400

Question

我在创建容器时遇到了问题，我使用的是 ubuntu 16.04 OS、docker 1.12.1、flannel 0.5.5 和 etcd 数据存储。

我是否需要在 /lib/systemd/system/docker.service 或 /etc/default/docker.有什么解决方法吗，我在几篇文章中读到 kubernetes 对最新的 docker 版本有一些问题。

对此的任何帮助和建议将不胜感激。

Answer 1

HostConfig 在 docker v1.12 中已弃用。 Kubernetes made a corresponding switch 在 v1.2 中弃用 HostConfig，因此您需要更新版本 (v1.2+) 的 kubernetes 才能与 docker v1.12 一起使用。

另一个需要注意的是，只有即将发布的 Kubernetes 1.4 版本声称与 docker v1.12 兼容。所有旧版本的 kubernetes 都没有针对 docker v1.12 进行测试。您最好使用旧版本的 docker，或者直接切换到 kubernetes v1.4 beta。
