Usage

import "github.com/retr0h/osapi/pkg/sdk/client"

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

// List all services
resp, err := c.Service.List(ctx, "web-01")
for _, r := range resp.Data.Results {
    for _, svc := range r.Services {
        fmt.Printf("%s status=%s enabled=%v\n",
            svc.Name, svc.Status, svc.Enabled)
    }
}

// Get a specific service
resp, err := c.Service.Get(ctx, "web-01", "nginx.service")
svc := resp.Data.First().Service
fmt.Printf("%s pid=%d\n", svc.Name, svc.PID)

// Start a service
resp, err := c.Service.Start(ctx, "web-01", "nginx.service")
fmt.Printf("changed=%v\n", resp.Data.First().Changed)

// Restart a service across all hosts
resp, err := c.Service.Restart(ctx, "_all", "nginx.service")
for _, r := range resp.Data.Results {
    fmt.Printf("%s changed=%v\n", r.Hostname, r.Changed)
}

// Deploy a new unit file
resp, err := c.Service.Create(ctx, "web-01",
    client.ServiceCreateOpts{
        Name:   "myapp.service",
        Object: "myapp-unit",
    })

// Update an existing unit file
resp, err := c.Service.Update(ctx, "web-01", "myapp.service",
    client.ServiceUpdateOpts{
        Object: "myapp-unit-v2",
    })

// Delete a unit file
resp, err := c.Service.Delete(ctx, "web-01", "myapp.service")
