docker version 1.9.1
swarm version 1.0.1
当将3个VM(桥接网络)连接到Swarm时,“docker info”会显示所有节点。
状态待定。
其中1个主机是管理器,所有输出都来自于此主机。我不知道该去哪里查找。
运行swarm --debug manage token://XXXXX
输出 >>
*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
那么
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
那么
root@ubuntu:~# swarm list token://xxxxxxxxxxx
10.32.1.4:2375
10.32.1.33:2375
10.32.1.38:2375
那么
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
心跳排序 - 在后台运行,检查端口、名称解析和是否可从管理器ping通。
