Question

我正在尝试从安装Java 8的Ubuntu 14.04构建基础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docker build -t memyself/docker_sample .时，我在安装Java时遇到以下错误：

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'

知道我哪里出错了吗？

我添加了apt-get install -y software-properties-common行，现在我获得了巨大的输出量，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），我会得到类似的信息＆＃34; 设备上没有剩余空间< / EM>＆＃34;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）。

Answer 1

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崩溃的原因。

docker info会显示文件的位置，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。

使用docker ps -a查找可以删除的容器，并使用docker rm -v将其删除（-v非常重要，因为它也会删除卷）。使用docker images查找不需要的图片，然后使用docker rmi删除它们。

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

Answer 2

尝试添加

apt-get install -y software-properties-common

获取add-apt-repository。在另一个RUN命令中或在您使用add-apt-repository之前。

Answer 3

可能是因为Docker.qcow2已满。

检查以下文件的大小 ls -lah ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2

有关此文件的mac的docker上有一个未解决的问题，这是一个包含yo的稀疏图像。见https://github.com/docker/for-mac/issues/371

我遇到了同样的问题，因为我不介意重建我的容器，我只是删除了Docker.qcow2，重新启动了docker，它解决了我的问题。请小心操作，尤其是如果您有大量依赖的图像且无法重建。

Mac上的Docker：设备上没有剩余空间
