How to use docker cli in golang to create subnet
问题
我正在尝试为我用Golang编写的应用程序创建一个Docker网络。
我知道可以使用这个NetworkCreate函数，但我不确定如何指定网络选项。
在常规终端控制台中，我可以使用以下命令创建网络：
docker network create -d bridge --subnet=174.3.12.5/16 mynet
但如何使用NetworkCreate()函数来等效地创建这个网络呢？
英文:
I'm trying to create a docker network for my application written in Golang.
I'm aware that I can use this NetworkCreate function, but I'm not sure how to specify the network option.
In the regular terminal console, I can just create the network with
docker network create -d bridge --subnet=174.3.12.5/16 mynet
But how to use the NetworkCreate() as an equivalent for this network creation?

package main
import (
"context"
"fmt"
"github.com/docker/docker/api/types"
"github.com/docker/docker/api/types/network"
"github.com/docker/docker/client"
)
func main() {
cli, err := client.NewClientWithOpts(client.FromEnv)
if err != nil {
fmt.Println(err)
}
newnetwork := types.NetworkCreate{IPAM: &network.IPAM{
Driver: "default",
Config: []network.IPAMConfig{network.IPAMConfig{
Subnet: "174.3.12.5/16",
}},
}}
res, err := cli.NetworkCreate(context.Background(), "test", newnetwork)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(res)
}
这是一个最小可实现的示例。驱动程序的名称是 default。
英文:
package main
import (
"context"
"fmt"
"github.com/docker/docker/api/types"
"github.com/docker/docker/api/types/network"
"github.com/docker/docker/client"
)
func main() {
cli, err := client.NewClientWithOpts(client.FromEnv)
if err != nil {
fmt.Println(err)
}
newnetwork := types.NetworkCreate{IPAM: &network.IPAM{
Driver: "default",
Config: []network.IPAMConfig{network.IPAMConfig{
Subnet: "174.3.12.5/16",
}},
}}
res, err := cli.NetworkCreate(context.Background(), "test", newnetwork)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(res)
}
this is a minimal implementable example. the name for driver is default.

您可以通过NetworkCreate选项结构来指定网络选项。
如果您想将命令docker network create -d bridge --subnet=174.3.12.5/16 mynet转换为等效的Go语言代码，可以像这样编写：
networkResponse, err := client.NetworkCreate(context.Background(), "mynet", types.NetworkCreate{
Driver: "bridge",
IPAM: &network.IPAM{
Config: []network.IPAMConfig{
{
Subnet: "174.3.12.5/16",
},
},
},
})
英文:
You can specify the network options via the NetworkCreate options struct.
If you want to convert the command docker network create -d bridge --subnet=174.3.12.5/16 mynet to a golang equivalent, It'll look something like this:
networkResponse, err := client.NetworkCreate(context.Background(), "mynet", types.NetworkCreate{
Driver: "bridge",
IPAM: &network.IPAM{
Config: network.IPAMConfig{
Subnet: "174.3.12.5/16",
},
},
})

你可以使用exec.Command(...).CombinedOutput()。
