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
    }
