Mac上的Docker:设备上没有剩余空间

Question

我正在尝试从安装Java 8的Ubuntu 14.04构建一个基本的Docker镜像.这是我到目前为止所拥有的:

FROM ubuntu:14.04
MAINTAINER Me Myself <memyself@example.com>

WORKDIR /

RUN \
    echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections && \
    apt-get install -y software-properties-common && \
    add-apt-repository -y ppa:webupd8team/java && \
    apt-get update && \
    apt-get install -y oracle-java8-installer && \
    rm -rf /var/lib/apt/lists/* && \
    rm -rf /var/cache/oracle-jdk8-installer

当我运行时,docker build -t memyself/docker_sample .我得到以下错误安装Java:

myuser@mymachine:~/sandbox/workspace/docker_sample$docker build -t memyself/docker_sample .

apt-get install -y oracle-java8-installer &&
rm -rf /var/lib/apt/lists/* &&   rm -rf /var/cache/oracle-jdk8-installer'

知道我哪里出错了？

更新:

我添加了这一apt-get install -y software-properties-common行,现在我得到了大量的输出,其中一些是:

重要的是要注意,如果我尝试在Mac上启动多个其他图像(从Docker Hub中提取),我会得到类似的" 设备上没有剩余空间 "错误.所以我认为这个最新的问题可能是因为没有为我的机器上的Docker分配足够的空间(类似于JVM OutOfMemoryException问题).

docker存储文件的文件系统已满.这就是解压缩下载的java archieve时tar压缩的原因.

docker info 将显示文件的位置,例如

Storage Driver: aufs
 Root Dir: /var/lib/docker/aufs

df -h 将告诉您文件系统上有多少磁盘空间可用.

使用docker ps -a发现可以删除容器,并删除他们docker rm -v(-v很重要,因为它还会删除卷).使用docker images找到需要的图像,并删除它们docker rmi.

您可能拥有不再需要的悬空图像图层.删除它们docker rmi $(docker images -q -f dangling=true).
