A rich golang client and server for container creation and management with pluggable backends for The Open Container Initiative Spec and windows.
Garden is a platform-agnostic Go API for container creation and management, with pluggable backends for different platforms and runtimes. This package contains the canonical client, as well as a server package containing an interface to be implemented by backends.
If you're just getting started, you probably want to begin by setting up one of the backends listed below. If you want to use the Garden client to manage containers, see the Client API section.
Backends implement support for various specific platforms. So far, the list of backends is as follows:
- Guardian - Linux backend using runc
- Greenhouse - Windows backend
The canonical API for Garden is defined as a collection of Go interfaces. See the godoc documentation for details.
Install needed packages:
go get code.cloudfoundry.org/garden
go get code.cloudfoundry.org/lager
Import these packages:
"bytes"
"fmt"
"os"
"code.cloudfoundry.org/garden"
"code.cloudfoundry.org/garden/client"
"code.cloudfoundry.org/garden/client/connection"
Create a client:
gardenClient := client.New(connection.New("tcp", "127.0.0.1:7777"))
Create a container:
container, err := gardenClient.Create(garden.ContainerSpec{})
if err != nil {
os.Exit(1)
}
Run a process:
buffer := &bytes.Buffer{}
process, err := container.Run(garden.ProcessSpec{
Path: "echo",
Args: []string{"hello from the container"},
}, garden.ProcessIO{
Stdout: buffer,
Stderr: buffer,
})
if err != nil {
os.Exit(1)
}
exitCode, err := process.Wait()
if err != nil {
os.Exit(1)
}
fmt.Printf("Exit code: %d, Process output %s", exitCode, buffer.String())
