"virtual memory exhausted" 构建 Docker 图像时

Question

构建 Docker 图像时，有一些 C++ 脚本的编译，我最终遇到如下错误：

src/amun/CMakeFiles/cpumode.dir/build.make:134: recipe for target 'src/amun/CMakeFiles/cpumode.dir/cpu/decoder/encoder_decoder_state.cpp.o' failed
virtual memory exhausted: Cannot allocate memory

但是在主机上构建相同的 .cpp 代码时，它工作正常。

经过一些检查，错误消息似乎与人们在 Raspberry Pi、https://www.bitpi.co/2015/02/11/how-to-change-raspberry-pis-swapfile-size-on-rasbian/

上看到的错误消息相似

经过更多谷歌搜索，Mac forum 上的 post 表示：

Swapfiles are dynamically created as needed, until either the disk is full, or the kernel runs out of page table space. I do not think you can change the page table space limits in the Mac OS X kernel. I have not seen anything in all the years I've been using OS X.

有没有办法在 Mac OS 的基础上为 Docker 增加交换 space？

如果没有，在构建 Docker 图像时还可以如何克服 "virtual memory exhausted" 错误？

Answer 1

这对于 XHyve 来说似乎并不简单。
如前所述 in this thread

I think the default size of the VM is 16GB. I kept running out of swap space even after bumping the ram on the VM up to 16GB.

检查用于 VirtualBox VM 的方法是否适用于 XHyve：参见“”

boot2docker ssh

export SWAPFILE=/mnt/sda1/swapfile
sudo dd if=/dev/zero of=$SWAPFILE bs=1024 count=4194304
sudo mkswap $SWAPFILE
sudo chmod 600 $SWAPFILE
sudo swapon $SWAPFILE

exit

还要检查此 Digital Ocean Setup，再次在您的 XHyve 上下文中进行测试。
mkswap is also seen here or in docker-root-xhyve/contrib/makehdd/makehdd.sh.

Answer 2

由于您的主机有足够的可用内存，我建议您为后面的 Docker 虚拟机分配更多内存。

如前所述：

As I can see that you are on OSX, which runs docker over a Linux VM. Configure the max memory clicking the whale icon in the task bar. By default is 2G.
