Question

由于公司的限制，我无法使用docker-swarm，因此我尝试在共享同一主机网络的多台计算机上设置领事群集，让我们假设这是3台计算机的地址（我将virtualbox与docker-machine一起用于测试），这些IP的容器称为HOST_IP：

dm1 ：192.168.99.100
dm2 ：192.168.99.101
dm3 ：192.168.99.102

CONSUL_BOOTSTRAP_IP是主要的领事引导服务器192.168.99.100。

此设置有效（我在Web UI中启动并运行了3个节点），但是在容器中却得到了一些奇怪的日志：

consul-server_1_46f1167db7a9 |     2018/11/14 08:06:48 [WARN] consul: error getting server health from "64bbf570ff39": rpc error getting client: failed to get conn: dial tcp <nil>->172.18.0.2:8300: connect: no route to host

consul-server_1_46f1167db7a9 |     2018/11/14 08:06:52 [WARN] consul: error getting server health from "64bbf570ff39": context deadline exceeded
consul-server_1_46f1167db7a9 |     2018/11/14 08:06:53 [WARN] consul: error getting server health from "64bbf570ff39": last request still outstanding
consul-server_1_46f1167db7a9 |     2018/11/14 08:06:54 [WARN] consul: error getting server health from "64bbf570ff39": rpc error getting client: failed to get conn: dial tcp <nil>->172.18.0.2:8300: connect: no route to host

为什么领事试图访问docker容器内部IP 172.18.0.*而不是使用-advertise地址？这很烦人，在用户界面中，我可以看到一些鬼节点的出现和消失以及错误状态。

这是我的撰写文件：
