Run standalone/docker-compose.yml with Podman

[chopeen]

I followed the article Using Compose Files with Podman and installed podman-compose on a RHEL machine.

podman-compose up -d was working fine with docker-compose.yml, but the Milvus standalone container was not starting because of error like:

last connection error: connection error: 
desc = \"transport: Error while dialing: dial tcp: lookup etcd on 145.245.102.102:53: no such host

Basically, it could not connect to the etcd host and it was trying to use regular DNS to resolve this name.

Running podman network inspect milvus showed the following:

[
     {
          "name": "milvus",
          ...
          "ipv6_enabled": false,
          "internal": false,
          "dns_enabled": false,
          ...
          "ipam_options": {
               "driver": "host-local"
          }
     }
]

"dns_enabled": false is the problem's root cause.

Installing podman-plugins to have the dnsname plugin fixed the issue.
