1. 首先流量从swarm manager 这台主机 192.168.3.43这个网卡进来,然后iptables PREROUTING 的规则有一条 我们可以看到当进来的流量目的端口是80的时候,会被dnat到172.18.0.2,这里我们需要知道172.18.0.2是谁的设备。这里需要知道的是,当我们docker swarm init后,会创建两个网络一个事ingress overlay 一个是docker_gwbri...
在公司服务器进行docker pull image,docker run 创建容器也都没有问题。但在docker swarm init的时候遇到一个很难解决的问题:error during connect: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.35/swarm/init: 和 dockerd[21754]: http: panic serving @: runtime error: index out of range。详细日志如下...
it makes dockerd exit immediately. Actually I only change the work place and IP changes, then I have no ability to use docker daemon. I think this is UNACCEPTABLE for users. I suggest that when swarm cluster init fails, it only affects the swarm part, not related to original API parts....

Docker 1.12内置swarm mode,即docker原生支持的docker容器集群管理模式,只要是执行了docker swarm init或docker swarm join到一个swarm cluster中,执行了这些命令的host上的docker engine daemon就进入了swarm mode。 swarm mode中,Docker进行了诸多抽象概念(这些概念与k8s、rancher中的概念大同小异,也不知是谁参考了谁^...

Error response from daemon: rpc error: code=4desc = context deadline exceeded 查看docker的log sudotail-f /var/log/messages |grepdocker 说明swarm cluster环境通信遇到了问题。 解决办法: 重新初始化cluster环境即可: docker swarm init --force-new-cluster 将node 重新加入即可解决...

sudo docker swarm init --advertise-addr 192.168.1.95 其中--advertise-addr用于配置一个IP地址,集群中其它节点使用此IP地址与管理节点通信,执行命令后输出如下: # 输出Swarm initialized: current node (vjs13uolge09ts9xpzm3tx09p) is now a manager. ...
