Docker工具箱无法分配内存

Question

我正在尝试让Docker在我一直在云中工作的Mac上本地运行一个容器。我做了docker commit / save / load查找。但是当我在安装docker toolbox之后必须在本地运行它时，出现此错误

docker logs es-loaded-with-data
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006c5330000, 4207738880, 0) failed; error='Cannot allocate memory' (errno=12)
Starting elasticsearch: #
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 4207738880 bytes for committing reserved memory.
# An error report file with more information is saved as:
# //hs_err_pid16.log

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006c5330000, 4207738880, 0) failed; error='Cannot allocate memory' (errno=12)
Starting elasticsearch: #

如果我这样做docker info然后我得到

总内存：1.956 GiB

显然2 Gb还不够。如何增加它以便我的容器运行？

Answer 1

Mac OS上的Docker在带有docker-machine（或更旧的boot2docker）的virtualbox VM内运行。我不确定docker-machine是否支持直接修改VM RAM，但是您可以直接启动VirtualBox.app并直接修改VM Memory的数量。重新启动虚拟机。

Answer 2

重新启动docker服务为我解决了问题。
