无法通过Docker桥接容器按名称ping主机网络

Question

06.1-ce

I have a container running in bridge newtork

"IPAM": {
  "Driver": "default",
  "Options": null,
  "Config": [
    {
      "Subnet": "172.18.0.0/16",
      "Gateway": "172.18.0.1"
    }
  ]
}

I can access my containers no problem, but I need to connect to a machine on the host network. When I docker exec -ti bash inside the container, I can ping by IP but not by name. Is that how Docker bridge network works?

Update

I can ping by full name. So is there a way to set the search domain for containers?

Answer 1

Ok we can set the DNS settings when using docker run

such as: --dns-search=mydomain.com
