Docker 1.12.1：在swarm init之后，worker不能joinswarm
我看到了这里和这里所描述的相同的问题。 我已经尝试了在这两种情况下工作的一切都无济于事 – 我仍然看到相同的行为。 有人可以提供替代品，我可以尝试？
我的设置：
我正在运行3个Centos 7.2盒。 networking时间协议（ntpd）在所有机器上运行。 所有已经百胜更新。 这里有一些详细的信息：
Linux version 3.10.0-327.28.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) Docker版本：
# docker version Client: Version: 1.12.1 API version: 1.24 Go version: go1.6.3 Git commit: 23cf638 Built: OS/Arch: linux/amd64 Server: Version: 1.12.1 API version: 1.24 Go version: go1.6.3 Git commit: 23cf638 Built: OS/Arch: linux/amd64
设置swarmpipe理器：
>docker swarm init --advertise-addr 10.1.1.40:2377 --force-new-cluster // on some retry attempts (after 'docker swarm leave --force') I ran: >docker swarm init --advertise-addr 10.1.1.40:2377 --force-new-cluster
经理状态：
>docker node inspect self [ { "ID": "3x5q1n9v956g3ptdle2eve856", "Version": { "Index": 10 }, "CreatedAt": "2016-08-27T13:01:13.400345797Z", "UpdatedAt": "2016-08-27T13:01:13.580143388Z", "Spec": { "Role": "manager", "Availability": "active" }, "Description": { "Hostname": "mymanagerhost.mycompany.com", "Platform": { "Architecture": "x86_64", "OS": "linux" }, "Resources": { "NanoCPUs": 4000000000, "MemoryBytes": 16659128320 }, "Engine": { "EngineVersion": "1.12.1", "Plugins": [ { "Type": "Network", "Name": "bridge" }, { "Type": "Network", "Name": "host" }, { "Type": "Network", "Name": "null" }, { "Type": "Network", "Name": "overlay" }, { "Type": "Volume", "Name": "local" } ] } }, "Status": { "State": "ready" }, "ManagerStatus": { "Leader": true, "Reachability": "reachable", "Addr": "10.1.1.40:2377" } } ]
在工人节点（我有两个，但他们都performance相同）。
join群：
>docker swarm join --token SWMTKN-1-4fjh7kncdpwjvxnxisamhldgenmmnqyvhnx9qdi8d4hkkfuacv-168gs9okd5ck0r4lokdgpef92 10.1.1.40:2377 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.
Docker信息命令的输出：

编辑下面的第一个答案
所以我试着离开停止/开始周围的命令。 我做了：
# docker swarm leave --force Node left the swarm. # service docker stop Redirecting to /bin/systemctl stop docker.service # # service docker start Redirecting to /bin/systemctl start docker.service # docker swarm init --advertise-addr 10.1.1.40:2377 Swarm initialized: current node (0e0y2k2hngnwyeg86ilzbrjmu) is now a manager. To add a worker to this swarm, run the following command: docker swarm join \ --token SWMTKN-1-2ggj60tnbppgjlg63a58oe5pqtv0vfrpj81hheawanf76x7cjc-7v48qak22wd03y3jyv903a9if \ 10.1.1.40:2377
然后在工作人员那里：
# docker swarm leave Node left the swarm. # service docker stop Redirecting to /bin/systemctl stop docker.service # service docker start Redirecting to /bin/systemctl start docker.service # docker swarm join \ > --token SWMTKN-1-2ggj60tnbppgjlg63a58oe5pqtv0vfrpj81hheawanf76x7cjc- 7v48qak22wd03y3jyv903a9if \ > 10.1.1.40:2377 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.
这显然是相同的行为…
UPDATE
我已经尝试了@Miad Abrin所描述的所有步骤。 我仍然得到同样的行为。 我猜测原因与我看到的CERTS错误有关：
# journalctl -xe Aug 29 12:26:15 dockerd[6577]: time="2016-08-29T12:26:15.554904435-04:00" level=warning msg="failed to retrieve remote root CA certificate: rpc Aug 29 12:26:15 dockerd[6577]: time="2016-08-29T12:26:15.555400400-04:00" level=warning msg="failed to retrieve remote root CA certificate: rpc Aug 29 12:26:15 dockerd[6577]: time="2016-08-29T12:26:15.555478782-04:00" level=warning msg="failed to retrieve remote root CA certificate: rpc Aug 29 12:26:15 dockerd[6577]: time="2016-08-29T12:26:15.555528929-04:00" level=warning msg="failed to retrieve remote root CA certificate: rpc Aug 29 12:26:15 dockerd[6577]: time="2016-08-29T12:26:15.555685464-04:00" level=warning msg="failed to retrieve remote root CA certificate: rpc
有谁知道这个原因以及如何纠正？
您需要在离开群集之前及之后重新启动Docker守护进程服务。 为群众领导和作品做好准备。 这是1.12版本中的一个错误，因为我遇到了同样的问题，所以在1.12.1修正了这个错误。
我尝试这个结果
