docker psする

package main

import (
        "context"
        "fmt"

        "github.com/docker/docker/api/types"
        "github.com/docker/docker/client"
)

func main() {
        cli, err := client.NewEnvClient()
        if err != nil {
                panic(err)
        }

        containers, err := cli.ContainerList(context.Background(), types.ContainerListOptions{})
        if err != nil {
                panic(err)
        }

        for _, container := range containers {
                fmt.Printf("%s %s\n", container.ID[:10], container.Image)
        }
}
