Docker-swarm>>无法连接到docker引擎端点 [英] Docker-swarm >> Cannot connect to the docker engine endpoint

问题描述

  docker版本1.9.1 
 swarm版本1.0.1 
  

为什么连接3个虚拟机（桥接网）到群集。 docker info显示所有节点

状态待决。

3个主机中有1个是管理器，所有输出都来自此主机。我不知道在哪里寻找。

运行 swarm --debug管理令牌：// XXXXX

output >>

  * INFO [0000]收听HTTP addr = 127.0.0.1：2375 proto = tcp 
 
 DEBU [0000]无法验证挂起的节点：无法连接到docker引擎端点Addr = 10.32.1.38：2375 
 
 DEBU [0000]无法验证挂起的节点：无法连接到docker引擎端点Addr = 10.32.1.4：2375 
 
 DEBU [0000]无法验证挂起的节点：无法连接到docker引擎端点Addr = 10.32.1.33：2375 
  

然后

  root @ ubuntu：〜＃ps -ef | grep swarm 
 
 root 2158 1391 0 12:28 pts / 2 00:00:00 swarm join token：// xxxxxxx --addr 10.32.1.4:2375 
 
 root 2407 1213 0 13:57 pts / 1 00:00:00群组管理令牌：// xxxxxxx -H 0.0.0.0:4243 
 
 root 2413 1391 0 13:57 pts / 2 00:00:00 grep --color = auto swarm 
  

然后

  root @ ubuntu：〜＃swarm list token：// xxxxxxxxxxx 
 
 10.32.1.4:2375 
 10.32.1.33:2375 
 10.32.1.38:2375 
  

然后

  root @ ubuntu：〜＃ps -ef | grep docker 
 
 root 2330 1 0 12:52？ 00:00:00 / usr / bin / docker守护进程
 
 root 2421 1391 0 14:10 pts / 2 00:00:00 grep --color = auto docker 
  

心跳排序 - 在后台运行，检查端口，名称解析，可从管理器ping。

解决方案

我已经在/ etc / default / docker中添加了DOCKER_OPTS值

DOCKER_OPTS = - H < >主机IP>：2375 -H unix：///var/run/docker.sock

更精确的是<<主机IP >>是您编辑/ etc / default / docker文件的主机IP。

也许它会帮助某人。

docker version 1.9.1
swarm version 1.0.1

why on connecting 3 VMs (bridged net) to swarm. "docker info" shows me all nodes

Status pending.

1 of 3 hosts is manager all output is from this host. I don't know where to look for.

On running swarm --debug manage token://XXXXX

output >>

*INFO[0000] Listening for HTTP addr=127.0.0.1:2375 proto=tcp

DEBU[0000] Failed to validate pending node: Cannot connect to the docker engine endpoint  Addr=10.32.1.38:2375

DEBU[0000] Failed to validate pending node: Cannot connect to the docker engine endpoint  Addr=10.32.1.4:2375

DEBU[0000] Failed to validate pending node: Cannot connect to the docker engine endpoint  Addr=10.32.1.33:2375

Then

root@ubuntu:~# ps -ef | grep swarm

root 2158  1391  0 12:28 pts/2 00:00:00 swarm join token://xxxxxxx --addr 10.32.1.4:2375

root 2407  1213  0 13:57 pts/1 00:00:00 swarm manage token://xxxxxxx -H 0.0.0.0:4243

root 2413  1391  0 13:57 pts/2    00:00:00 grep --color=auto swarm

Then

root@ubuntu:~# swarm list token://xxxxxxxxxxx

10.32.1.4:2375
10.32.1.33:2375
10.32.1.38:2375

Then

root@ubuntu:~# ps -ef | grep docker

root      2330     1  0 12:52 ?        00:00:00 /usr/bin/docker daemon

root      2421  1391  0 14:10 pts/2    00:00:00 grep --color=auto docker

heartbeat sorted - runs in background, checked ports, name resolution, pingable from manager.

解决方案

I have added DOCKER_OPTS values in /etc/default/docker

DOCKER_OPTS="-H <>host IP<>:2375 -H unix:///var/run/docker.sock"

to be more precise << Host IP >> is same host IP you editing your /etc/default/docker file.

Maybe it will help someone.
