Docker Machine:设备上没有剩余空间 [英] Docker Machine: No space left on device
问题描述
我正在尝试使用Docker Compose设置Docker Machine。
I'm trying to set up Docker Machine with Docker Compose.
方案1(无Docker Machine)
如果我在没有Docker Machine的情况下运行 docker-compose up -d
,它将按意图创建我的3个链接容器(nginx + mongodb + nodejs)。
Scenario 1 (without Docker Machine)
If I run docker-compose up -d
without Docker Machine, it creates my 3 linked containers as intented (nginx+mongodb+nodejs).
场景2(使用Docker计算机)
然后,我使用Docker Machine创建VM,并告诉Docker使用<$ c与该计算机对话$ c> eval $(docker-machine env streambacker-dev)。
在这一点上,如果我使用shsh进入docker计算机并运行 df -h
,我得到:
At this point, if I ssh to my docker machine and run df -h
, I get:
如果我然后运行 docker-compose up -d
,下载最后一个容器时,出现设备上没有剩余空间错误。
If I then run docker-compose up -d
, I get a "no space left on device" error while downloading the last container.
tmpfs之后似乎确实有点满了:
"tmpfs" seems to be indeed a bit full after that:
检查-virtualbox-disk-size 选项显示其默认设置到20000 MB,我认为这是我们在两张图片上都可以看到的 / dev / sda1。那么,为什么容器会填充 tmpfs n,而 tmpfs到底是什么呢?是一个临时下载目录吗? 如何为容器创建更多空间?
Checking the --virtualbox-disk-size option shows that it defaults to 20000 MB, which I think is what we can see as "/dev/sda1" on both pictures. So why are containers filling up "tmpfs" n and what exactly is "tmpfs"? Is is a temporary download directory? How can I create more space for my containers?
谢谢!
对于信息,我正在使用 Docker Machine 0.4.0-rc2 和 Docker Compose 1.3.2 。
For information, I'm using Docker Machine 0.4.0-rc2 and Docker Compose 1.3.2.
推荐答案
就像上面说的, tmpfs
与 --virtualbox-disk-size $ c无关$ c>。似乎boot2docker将
tmpfs
装入内存,因此您需要为virtualbox vm分配更多的内存。您可以通过指定-virtualbox-memory
参数来实现。
Like said above, the tmpfs
has nothing to do with --virtualbox-disk-size
. It seems like boot2docker mounts tmpfs
into memory, so you need to dedicate more memory to your virtualbox vm. You can do it by specifying the --virtualbox-memory
parameter.
--virtualbox-memory "1024"
Size of memory for host in MB [$VIRTUALBOX_MEMORY_SIZE]
默认值:
$ docker-machine create --driver virtualbox testA
Creating VirtualBox VM...
Creating SSH key...
Starting VirtualBox VM...
Starting VM...
$ docker-machine ssh testA
