The docker command uses this package to communicate with the daemon. It can also be used by your own Go applications to do anything the command-line interface does – running containers, pulling images, managing swarms, etc.
For example, to list all containers (the equivalent of docker ps --all):
package main
import (
"context"
"fmt"
"github.com/docker/docker/api/types/container"
"github.com/docker/docker/client"
)
func main() {
apiClient, err := client.NewClientWithOpts(client.FromEnv)
if err != nil {
panic(err)
}
defer apiClient.Close()
containers, err := apiClient.ContainerList(context.Background(), container.ListOptions{All: true})
if err != nil {
panic(err)
}
for _, ctr := range containers {
fmt.Printf("%s %s (status: %s)\n", ctr.ID, ctr.Image, ctr.Status)
}
}
