networkCreate failing to create overlay networks #368
Description
Repro:
docker, err := client.NewClient("unix:///var/run/docker.sock", "v1.24", nil, nil)
handleErr(err)
res, err := docker.ServerVersion(context.Background())
handleErr(err)
_, err = docker.NetworkCreate(context.Background(), "zzzzzzzzzz", types.NetworkCreate{
CheckDuplicate: true,
Driver: "overlay",
EnableIPv6: false,
})
handleErr(err)Error:
{"message":"rpc error: code = 3 desc = driver name: if driver is specified name is required"
engine-api posts the following data:
{
"CheckDuplicate": true,
"Driver": "overlay",
"EnableIPv6": false,
"IPAM": {
"Driver": "",
"Options": null,
"Config": null
},
"Internal": false,
"Options": null,
"Labels": null,
"Name": "zzzzzzzzzz"
}The Docker cli uses the following data to create the request:
{
"CheckDuplicate": true,
"Driver": "overlay",
"EnableIPv6": false,
"IPAM": {
"Driver": "default",
"Config": [],
"Options": {}
},
"Internal": false,
"Options": {}
"Labels": {},
"Name": "zzzzzzzzzz",
}Workaround:
Set the following field in the NetworkCreate struct:
IPAM: network.IPAM{Driver: "default"}
This could probably be blamed on docker for not accepting empty string as the IPAM driver, so I'll open an issue there too.
