Usage

import "github.com/osapi-io/osapi/pkg/sdk/client"

c := client.New("http://localhost:8080", token)

// List all interfaces
resp, err := c.Interface.List(ctx, "web-01")
for _, r := range resp.Data.Results {
    for _, iface := range r.Interfaces {
        fmt.Printf("%s: state=%s\n",
            iface.Name, iface.State)
    }
}

// Get a specific interface
resp, err := c.Interface.Get(ctx, "web-01", "eth0")
iface := resp.Data.First().Interface
fmt.Printf("Addresses: %v\n", iface.Addresses)

// Create a static interface config
dhcp4 := false
resp, err := c.Interface.Create(ctx, "web-01", "eth0",
    client.InterfaceConfigOpts{
        DHCP4:     &dhcp4,
        Addresses: []string{"192.168.1.100/24"},
        Gateway4:  "192.168.1.1",
    })
fmt.Printf("changed=%v\n", resp.Data.First().Changed)

// Update an existing config
resp, err := c.Interface.Update(ctx, "web-01", "eth0",
    client.InterfaceConfigOpts{
        Addresses: []string{"192.168.1.200/24"},
        Gateway4:  "192.168.1.1",
    })

// Delete an interface config
resp, err := c.Interface.Delete(ctx, "web-01", "eth0")
fmt.Printf("changed=%v\n", resp.Data.First().Changed)

// Broadcast interface create to all hosts
dhcp4 := true
resp, err := c.Interface.Create(ctx, "_all", "eth1",
    client.InterfaceConfigOpts{DHCP4: &dhcp4})
for _, r := range resp.Data.Results {
    fmt.Printf("%s changed=%v\n", r.Hostname, r.Changed)
}
