如何通过tcp-socker访问Docker守护程序? [英] How to access Docker daemon through tcp-socker?
问题描述
我已经添加了
DOCKER_OPTS="-H tcp://0.0.0.0:2375"
到/ etc / default / docker使Docker API在主机上可以访问(我在Virtualbox中运行Docker一个Ubuntu虚拟机)。但是,当我尝试运行任何Docker命令时,我只收到这个错误消息:
to /etc/default/docker to make the Docker API accessible on my host machine (I'm running Docker in Virtualbox on an Ubuntu VM). However, when I try to run any Docker commands now, I just get this error message:
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
我已经尝试过sudo服务docker重新启动,重新启动机器,但没有任何工作。任何想法是什么问题?
I have tried sudo service docker restart, and restarted the machine, but nothing has worked. Any idea what the problem is?
推荐答案
要通过tcp套接字使用守护程序,选项 -H tcp://0.0.0.0:2375
应该添加到命令 docker
(都为守护程序
和运行
)。
To use the daemon through the tcp socket the option -H tcp://0.0.0.0:2375
should be added to the command docker
(both for the daemon
and run
).
要使用其默认unix套接字访问守护程序,请确保Docker守护进程也从选项 -H = unix:///var/run/docker.sock
开始。
To access the daemon with its default unix socket make sure that the Docker daemon is also started with the option -H=unix:///var/run/docker.sock
.
请注意,如果您不信任您所在的网络,则使用 tcp
是危险的。页面:
Note that using the tcp
is dangerous if you do not trust the network you are in. Here is the doc from the man page:
-H, --host=[unix:///var/run/docker.sock]: tcp://[host]:[port][path] to bind or unix://[/path/to/socket] to use.
The socket(s) to bind to in daemon mode specified using one or more
tcp://host:port/path, unix:///path/to/socket, fd://* or fd://socketfd.
If the tcp port is not specified, then it will default to either 2375 when
--tls is off, or 2376 when --tls is on, or --tlsverify is specified.
