Docker：/var/run/docker.sock：没有这样的文件或目录 [英] Docker : /var/run/docker.sock: no such file or directory
问题描述
Infra
我正在尝试设置一个介质 - 马拉松集群分发容器。
在我的主服务器上，我有：
- zookeeper
- docker注册表v2 5000）wo credentials
- 带有supervisord + mesos + marathon的容器
此外，我有一个奴隶（在同一台服务器上）。
$ docker ps
192.168.0.38:5000/mesos-slave:prod mesos-slave-1
192.168.0.38:5000/mesos-master:generic mesos-master
jplock / zookeeper 0.0.0.0:2181->2181/tcp，0.0.0.0:2888-> 2888 / tcp，0.0.0.0:3888->3888/tcp nostalgic_visvesvaraya
注册表：2 0.0.0.0:5000->5000/tcp注册表
发行
我的问题是我不能马拉松将码头图像发送给slav e。
我认为这是从奴隶的配置。
$ docker exec -ti mesos-slave-1 / bin / bash
root @ xw8600-Workstation：/＃docker info
获取http：///var/run/docker.sock/v1。 19 / info：拨打unix /var/run/docker.sock：没有这样的文件或目录。您是否尝试连接到不带TLS的启用TLS的守护程序？
问题出在{dial unix /var/run/docker.sock：没有这样的文件或目录}
Slave的Dockerfile
从属机的Docker文件或多或少是这样的：
FROM 192.168.0.38:5000/supervisor:prod
运行apt-get -y --fix-missing更新
运行apt-get install -y --force-yes mesos
#Mesos
RUN echo'docker，mesos'> / etc / mesos-slave / containerizers
RUN echo'5mins'> / etc / mesos-slave / executor_registration_timeout
COPY mesos-slave.conf /etc/supervisor/conf.d/mesos-slave.conf
CMD supervisord -c / etc /supervisor.conf
mesos-slave.conf如下所示：
[程序：mesos-slave]
command = mesos-slave --master =％（ENV_MASTER）s --ip =％（ENV_IP） s --hostname =％（ENV_HOSTNAME）s --resources =％（ENV_RESOURCES）s --attributes =％（ENV_ATTRIBUTES）s --port =％（ENV_SLAVE_PORT）s --log_dir = / etc / mesos / logs --containerizers = docker，mesos --no-switch_user
我在错误日志中总是出现相同的错误。拉rstudio的例子：
无法启动：无法停靠Docker -H unix：/// var / run / docker。袜子拉192.168.0.38:5000:rocker/rstudio'：退出状态=退出状态1 stderr =发布http：///var/run/docker.sock/v1.19/images/create？fromImage = 192.168.0.38％ 3A5000％3Arocker％2Frstudio％3Alatest：拨打unix /var/run/docker.sock：没有这样的文件或目录。您是否尝试连接到不带TLS的启用TLS的守护程序？
我做错了什么？
编辑
似乎我无法启动docker
root @ xw8600 - 工作站：/ var / log / upstart＃sudo /etc/init.d/docker status
* Docker没有运行
root @ xw8600-Workstation：/ var / log / upstart＃sudo / etc / init.d / docker start
*启动Docker：docker
...完成。
root @ xw8600-Workstation：/ var / log / upstart＃sudo /etc/init.d/docker status
* Docker没有运行

按照我的问题这里：我有一个mesos slave（v1.7）尝试在码头运行中得到码头。
当我在容器内部时，我收到以下错误日志：
$ cat / var / log / docker .log/ pre>
time =2015-10-17T12：27：40.963674511Zlevel = fatal msg =启动守护程序时出错：初始化graphdriver错误：不允许操作
我在互联网上找不到很多信息，这里有一些类似的问题：
- https://github.com/jpetazzo/dind/issues/89
- https://github.com/docker / docker / issues / 14543
- Ubuntu上的Docker hello-world - 权限被拒绝
解决方案你不能在docker容器内重新启动docker。 您可以在码头集装箱内运行码头服务器但是重新启动？ （如果我错了，请更正）
本质上，您正在停止容器xw8600-Workstation中的docker守护程序，而容器本身正在使用相同的docker守护进程。
一个更好的架构就是让你的介质从属设备在一个普通的虚拟机或裸机上，然后在那里运行你的docker守护进程，让mesos /马拉松管理你的资源通过Docker。希望有意义。

I am trying to set up a mesos<->marathon cluster distributing containers. On my main server I have:
- zookeeper
- docker registry v2 (port 5000) wo credentials
- a container with supervisord + mesos + marathon
Furthermore I have a slave (on the same server).
$docker ps 192.168.0.38:5000/mesos-slave:prod mesos-slave-1 192.168.0.38:5000/mesos-master:generic mesos-master jplock/zookeeper 0.0.0.0:2181->2181/tcp, 0.0.0.0:2888->2888/tcp, 0.0.0.0:3888->3888/tcp nostalgic_visvesvaraya registry:2 0.0.0.0:5000->5000/tcp registry
Issue
My issue is that I can't have marathon sending a docker image to the slave.
I think this comes from the configuration of the slave.
$ docker exec -ti mesos-slave-1 /bin/bash root@xw8600-Workstation:/# docker info Get http:///var/run/docker.sock/v1.19/info: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?The issue is on the {dial unix /var/run/docker.sock: no such file or directory}.
Slave's Dockerfile
The Dockerfile for the slave looks more or less like that :
FROM 192.168.0.38:5000/supervisor:prod RUN apt-get -y --fix-missing update RUN apt-get install -y --force-yes mesos #Mesos RUN echo 'docker,mesos' > /etc/mesos-slave/containerizers RUN echo '5mins' > /etc/mesos-slave/executor_registration_timeout COPY mesos-slave.conf /etc/supervisor/conf.d/mesos-slave.conf CMD supervisord -c /etc/supervisor.confThe mesos-slave.conf looks like that :
[program:mesos-slave] command=mesos-slave --master=%(ENV_MASTER)s --ip=%(ENV_IP)s --hostname=%(ENV_HOSTNAME)s --resources=%(ENV_RESOURCES)s --attributes=%(ENV_ATTRIBUTES)s --port=%(ENV_SLAVE_PORT)s --log_dir=/etc/mesos/logs --containerizers=docker,mesos --no-switch_userI get always the same error on the error log. Example to pull rstudio :
failed to start: Failed to 'docker -H unix:///var/run/docker.sock pull 192.168.0.38:5000:rocker/rstudio': exit status = exited with status 1 stderr = Post http:///var/run/docker.sock/v1.19/images/create?fromImage=192.168.0.38%3A5000%3Arocker%2Frstudio%3Alatest: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?What do I do wrong ?
Edit
It seems I can not start docker
root@xw8600-Workstation:/var/log/upstart# sudo /etc/init.d/docker status * Docker is not running root@xw8600-Workstation:/var/log/upstart# sudo /etc/init.d/docker start * Starting Docker: docker ...done. root@xw8600-Workstation:/var/log/upstart# sudo /etc/init.d/docker status * Docker is not running

Following my question here : I have a mesos slave (v1.7) on which I try to get a docker in docker running. When I am inside the container, I get the following error log :
$ cat /var/log/docker.log time="2015-10-17T12:27:40.963674511Z" level=fatal msg="Error starting daemon: error initializing graphdriver: operation not permitted"I can't find much info on internet, here are some similar questions:
- https://github.com/jpetazzo/dind/issues/89
- https://github.com/docker/docker/issues/14543
- Docker hello-world on Ubuntu - permission denied
解决方案You cannot restart docker within a docker container. You can run docker within a docker containers But restarting? (Correct me if I'm wrong)
Essentially, you are stopping the docker daemon in your container 'xw8600-Workstation' while the container itself is using the very same docker daemon.
A better architecture is to just have your mesos-slave in a plain VM or bare-metal then run your docker daemon there and let mesos/marathon manage your resources through Docker. Hope it makes sense.
