Docker1.12工人无法加入群集（Swarm：Pending） [英] Docker1.12 Worker not able to join in cluster(Swarm: Pending)
问题描述
管理器版本 Docker版本1.12.0-rc5，构建a3f2063 ，
工作版本 Docker版本1.12.0-rc5，构建a3f2063 。
创建Swarm管理器：
$ pre> $ code> docker swarm init --advertise-addr172.25.30.2:4243
Swarm已初始化：当前节点（3kmewyb10p8xj3ke5rpjyw4s8）现在是一个经理。
要向此群组添加一个工作人员，请运行以下命令：
docker swarm join \
--token SWMTKN-1-5lwzvv7au6hosiqqmdwmcxvmlmhtz4ts04jsg06284fq3posn0-enq26dqnwma38ij48hymtnioq \
172.25.30.2:4243
要向此群组添加管理员，请运行以下命令：
docker swarm join \
--token SWMTKN-1-5lwzvv7au6hosiqqmdwmcxvmlmhtz4ts04jsg06284fq3posn0-85cwe5pf779qw0knjn6wxdbim \\ \\
172.25.30.2:4243
然后创建工作
docker swarm join --token SWMTKN-1-5lwzvv7au6hosiqqmdwmcxvmlmhtz4ts04jsg06284fq3posn0-enq26dqnwma38ij48hymtnioq 172.25.30.2:4243
守护进程错误响应：在节点加入之前超时。尝试加入群集将在后台继续。使用docker info命令查看节点的当前群组状态。
我已检查工作中的日志

在 docker信息中，我看到Swarm：Pending
我做了 docker swarm update 还有，工作人员无法加入群集，所以，如何重新开发
UPDATE-1
卸载和删除配置文件，然后再次使用版本 Docker版本1.12.0安装docker 1.12，build 8eab29e 。
仍然面临同样的问题（无法在 docker info ）在 /var/logs/upstat/docker.logs中的DIFFERENT错误
time =2016-08-01T11：22：08.629760770-07：00level = error msg =POST / v1.24/swarm/join的处理程序返回错误：节点加入之前已达到超时。尝试加入群集将在后台继续。使用\docker info\命令查看节点当前的群组状态。
谢谢。
事情是，我试图加入错误的端口（As docker
1）在docker swarm init之前，端口号在端口上运行4243，我已经使用 netstat -tulp | grep docker 检查，所以我用那个端口做广告！
root @ veeru：〜＃netstat -tulpn | grep docker
tcp6 0 0 ::: 4243 ::: * LISTEN 8750 / dockerd
root @veeru：〜＃docker swarm init --advertise-addr172.25.30.2:4243
Swarm initialized：当前节点（exvwgj0pu4cd124ljnblt9xff）现在是一个经理
要添加一个工作器这个群组，运行以下命令：
docker swarm join \
--token SWMTKN-1-5j9mpo8hepue6g1sjdas33thr92w1o9hlef5auwqpbxs3glt39-6zom hgu204m9alq51f632nzas \
172.25.30.2:4243
要向此群组添加管理器，请运行以下命令：
docker swarm join \
--token SWMTKN -1-5j9mpo8hepue6g1sjdas33thr92w1o9hlef5auwqpbxs3glt39-axhgqgo4jqw4hv38x578m44wh \
172.25.30.2:4243
2在 docker swarm init 之后，码头服务器正在运行4端口，包括端口 2377 （ netstat -tupln | grep docker ）。
root @ veeru：〜＃netstat -tulp | grep docker
tcp6 0 0 [::]：2377 [::]：* LISTEN 8750 / dockerd
tcp6 0 0 [::]：7946 [::]：* LISTEN 8750 / dockerd
tcp6 0 0 [::]：4243 [::]：* LISTEN 8750 / dockerd
udp6 0 0 [::]：7946 [::]：* 8750 / dockerd
在第1点，它正在告诉运行 docker swarm join code> 4243 在工作。以前我没有像那样运行！（它不工作！）
稍后我做了$ code> docker swarm leave 并加入端口 2377 。现在我可以加入！
docker swarm join --token SWMTKN-1-5j9mpo8hepue6g1sjdas33thr92w1o9hlef5auwqpbxs3glt39-6zomhgu204m9alq51f632nzas 172.25.30.2:2377
Manager Version Docker version 1.12.0-rc5, build a3f2063,
Worker version Docker version 1.12.0-rc5, build a3f2063.
Created Swarm manger:
docker swarm init --advertise-addr "172.25.30.2:4243"
Swarm initialized: current node (3kmewyb10p8xj3ke5rpjyw4s8) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-5lwzvv7au6hosiqqmdwmcxvmlmhtz4ts04jsg06284fq3posn0-enq26dqnwma38ij48hymtnioq \
172.25.30.2:4243
To add a manager to this swarm, run the following command:

172.25.30.2:4243
Then created worker
docker swarm join --token SWMTKN-1-5lwzvv7au6hosiqqmdwmcxvmlmhtz4ts04jsg06284fq3posn0-enq26dqnwma38ij48hymtnioq 172.25.30.2:4243
Error response from daemon: Timeout was reached before node was joined. Attempt to join the cluster will continue in the background. Use "docker info" command to see the current swarm status of your node.
I have checked logs in worker

In docker info, I saw "Swarm: Pending"
I did docker swarm update also!. Still, the worker was not able to join the cluster. So, how can I reslove
UPDATE-1
Uninstalled & removed config files and then install docker 1.12 again with version Docker version 1.12.0, build 8eab29e.
Still facing the same problem(Not able to join and "Swarm:Pending" in docker info) with DIFFERENT error in /var/logs/upstat/docker.logs
time="2016-08-01T11:22:08.629760770-07:00" level=error msg="Handler for POST /v1.24/swarm/join returned error: Timeout was reached before node was joined. Attempt to join the cluster will continue in the background. Use \"docker info\" command to see the current swarm status of your node."
Thanks.
The thing is, I was trying to join with wrong "port" (As docker swarm init shown in output).
1) Before "docker swarm init", the docker running on port "4243" only. I have checked with netstat -tulp | grep docker. So I advertised with that port!
root@veeru:~# netstat -tulpn | grep docker
tcp6 0 0 :::4243 :::* LISTEN 8750/dockerd
root@veeru:~# docker swarm init --advertise-addr "172.25.30.2:4243"

172.25.30.2:4243
2) After docker swarm init, the docker is running with 4 port including the port 2377(netstat -tupln | grep docker).
root@veeru:~# netstat -tulp | grep docker
tcp6 0 0 [::]:2377 [::]:* LISTEN 8750/dockerd
tcp6 0 0 [::]:7946 [::]:* LISTEN 8750/dockerd
tcp6 0 0 [::]:4243 [::]:* LISTEN 8750/dockerd
udp6 0 0 [::]:7946 [::]:* 8750/dockerd
In point 1, it is telling to run docker swarm join with port 4243 in worker. Previously I did run like that!.(It wont work!)
Later I did docker swarm leave and joined with port 2377. Now I am able to join!
docker swarm join --token SWMTKN-1-5j9mpo8hepue6g1sjdas33thr92w1o9hlef5auwqpbxs3glt39-6zomhgu204m9alq51f632nzas 172.25.30.2:2377
