运行 Windows 容器时，如何为 Docker for Windows 使用的 Windows VM 分配更多内存？

Question

我的镜像的 Dockerfile 现在非常简单：

FROM openjdk:11.0-windowsservercore-ltsc2016
RUN mkdir artifactory
ADD artifactory-pro-6.3.3 artifactory/
# systeminfo for debugging purposes only
RUN systeminfo
RUN C:\\artifactory\bin\artifactory

systeminfo 调用的输出包括以下内容：

OS Name:                   Microsoft Windows Server 2016 Datacenter

如您所见，“Virtual Memory: Max Size”和“Total Physical Memory”属性设置为仅为 1023 MB。我的 docker info 包括以下内容：

Containers: 24

Architecture: x86_64
CPUs: 16
Total Memory: 31.68GiB

我正在使用以下命令启动我的容器：

docker run -it --name testing -m 8G artifactory-server:latest

然而似乎只有 1G 可用。这是有问题的，因为当我尝试启动 Artifactory 时，Java 运行时环境内存不足，并且容器没有启动。

这是我第一次涉足 Docker for Windows，所以我可能配置有误。我遇到的潜在解决方案引用了 VirtualBox，由于它与 Hyper-V 和运行的 Windows 容器不兼容，我没有。

我没有看到其他人似乎看到的“高级”设置，这让我怀疑我是否拥有正确版本的 Docker。

编辑：经研究，我在“设置”菜单中看不到“共享驱动器”、“网络”和“Kubernetes”选项卡的原因似乎是因为它们仅适用于 Linux 容器。

任何方向将不胜感激。

谢谢！

我正在为 Windows 使用 docker 桌面（使用 hyper-v）。 更改内存的步骤：

1. 右键单击docker桌面图标。

2. 设置

3. 资源

4. ADVANCED 您可以在此子页面中更改 cpus/memory/swap。

5. 应用并重新启动。

6. 查看效果：

您应该将 Windows/Docker 更新到最新版本。在我的设置中，Windows 版本 22H2（OS Build 19045.2604）和 Docker 版本

docker version

    Client:
     Cloud integration: v1.0.29
     Version:           20.10.22

     Engine:

      Experimental:     false

-m 8G

开关工作正常：

docker run --rm -m 8G openjdk:11.0-windowsservercore-ltsc2016 systeminfo
