2022-12-23：portainer是docker的web可视化工具。如果根据docker部署去写yaml，默认local是k8s，而不是docker，这不符合需求，需要修改yaml。请问部署在 k3s 中，并且默认local是docker，yaml 文件如何写？

答案2022-12-23：

1.portainer在默认情况下用的是k8s环境，所以需要改成docker环境，根据如下代码块一的go代码可知，把"KUBERNETES_SERVICE_HOST"环境变量设置为空，就会把默认环境变成docker环境。
2.根据命令行参数，给–admin-password一个值，你就不需要创建用户了。
3.–admin-password是一个哈希值，根据如下代码块二的go代码可知，需要将密码转成哈希才行。“moonfdd–moonfdd"转换成哈希是”$2a$10$4m4rYwK/TA8GRkyz4UrZ2e8B4GDG8ZhBkyGawJ05q1zJ7zmLywzmW"。

// 代码块一
// api/platform/platform.go

const (
	PodmanMode            = "PODMAN"
	KubernetesServiceHost = "KUBERNETES_SERVICE_HOST"
	NomadJobName          = "NOMAD_JOB_NAME"
)

// DetermineContainerPlatform will check for the existence of the PODMAN_MODE
// or KUBERNETES_SERVICE_HOST environment variable to determine if
// the container is running on Podman or inside the Kubernetes platform.
// Defaults to Docker otherwise.
func DetermineContainerPlatform() (ContainerPlatform, error) {
	podmanModeEnvVar := os.Getenv(PodmanMode)
	if podmanModeEnvVar == "1" {
		return PlatformPodman, nil
	}
	serviceHostKubernetesEnvVar := os.Getenv(KubernetesServiceHost)
	if serviceHostKubernetesEnvVar != "" {
		return PlatformKubernetes, nil
	}
	nomadJobName := os.Getenv(NomadJobName)
	if nomadJobName != "" {
		return PlatformNomad, nil
	}

	if !isRunningInContainer() {
		return "", nil
	}

	dockerCli, err := client.NewClientWithOpts()
	if err != nil {
		return "", errors.WithMessage(err, "failed to create docker client")
	}
	defer dockerCli.Close()

	info, err := dockerCli.Info(context.Background())
	if err != nil {
		if client.IsErrConnectionFailed(err) {
			log.Warn().
				Err(err).
				Msg("failed to retrieve docker info")
			return "", nil
		}

		return "", errors.WithMessage(err, "failed to retrieve docker info")
	}

	if info.Swarm.NodeID == "" {
		return PlatformDockerStandalone, nil
	}

	return PlatformDockerSwarm, nil
}

// 代码块二
// api/cmd/portainer/main.go
	adminPasswordHash := ""
	if *flags.AdminPasswordFile != "" {
		content, err := fileService.GetFileContent(*flags.AdminPasswordFile, "")
		if err != nil {
			log.Fatal().Err(err).Msg("failed getting admin password file")
		}

		adminPasswordHash, err = cryptoService.Hash(strings.TrimSuffix(string(content), "\n"))
		if err != nil {
			log.Fatal().Err(err).Msg("failed hashing admin password")
		}
	} else if *flags.AdminPassword != "" {
		adminPasswordHash = *flags.AdminPassword
	}

yaml如下：
