推荐答案

尽管这个问题很旧，但由于没有答案，我决定发布一个问题.

Although this question is old, as it has no answer I have decided to post one.

实际上，现在仅通过在创建容器时使用选项-memory-swap 即可支持禁用内存交换.根据

Indeed, disabling memory swap is now supported by just using the option --memory-swap when creating the container. You simply have to set --memory and --memory-swap to the same value, according to the docs.
