Container host resolution fails with compose 2.0 file format

[sauliusvl]

Hi,

when using the new 2.0 file format compose creates a new docker network every time, so if you do docker inspect on any of the containers you get something like this:

"NetworkSettings": {
   "Bridge": "",
   "SandboxID": "09599d0d6575a5c1790f09fca7f9a38f89421516bb48b9b9adf868bd6bd0bb80",
   "HairpinMode": false,
   "LinkLocalIPv6Address": "",
   "LinkLocalIPv6PrefixLen": 0,
   "Ports": {},
   "SandboxKey": "/var/run/docker/netns/09599d0d6575",
   "SecondaryIPAddresses": null,
   "SecondaryIPv6Addresses": null,
   "EndpointID": "",
   "Gateway": "",
   "GlobalIPv6Address": "",
   "GlobalIPv6PrefixLen": 0,
   "IPAddress": "",
   "IPPrefixLen": 0,
   "IPv6Gateway": "",
   "MacAddress": "",
   "Networks": {
       "910330_default": {
           "IPAMConfig": null,
           "Links": null,
           "Aliases": [
               "zookeeper",
               "72471c8769e1"
           ],
           "NetworkID": "9a147c09c7f873c1ded7ad8743a7cf82fec1849a0827ed0dfc6c5ca33fa12a1c",
           "EndpointID": "5ea92039c19addeb85c32d2484e7c87b896b13e48099a0a4a688c52b308aa457",
           "Gateway": "172.18.0.1",
           "IPAddress": "172.18.0.2",
           "IPPrefixLen": 16,
           "IPv6Gateway": "",
           "GlobalIPv6Address": "",
           "GlobalIPv6PrefixLen": 0,
           "MacAddress": "02:42:ac:12:00:02"
       }
   }
}

Note that Gateway is empty, so the current approach to determine the host gives an empty string.

Everything works as expected with 1.0 compose format.

Not sure what are your plans regarding 2.0, but I suppose a warning in the docs would be nice at the very least :)

Hi @sauliusvl,

Thanks for the detailed write-up! Docker-Compose 2.0 came out after this plugin was released but we fully intend to support it. I published a new SNAPSHOT release that contains a fix to read the new 2.0 network information if it exists:

addSbtPlugin("com.tapad" % "sbt-docker-compose" % "1.0.4-SNAPSHOT")

Let me know if that works for you and if so I can publish a new official release.

[sauliusvl]

Yes, the snapshot version works properly, waiting for the new version :)

[kurtkopchik]

The official 1.0.5 release is now live: addSbtPlugin("com.tapad" % "sbt-docker-compose" % "1.0.5")

Closing out this issue. Please open a new one if you hit another problem. Thanks for using the plugin!
