本文整理汇总了Golang中github.com/openshift/origin/pkg/cmd/util/docker.Helper类的典型用法代码示例。如果您正苦于以下问题：Golang Helper类的具体用法？Golang Helper怎么用？Golang Helper使用的例子？那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。

在下文中一共展示了Helper类的3个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: EnsureDocker

// EnsureDocker attempts to connect to the Docker daemon defined by the helper,
// and if it is unable to it will print a warning.
func (c *NodeConfig) EnsureDocker(docker *dockerutil.Helper) {
	dockerClient, dockerAddr := docker.GetClientOrExit()
	if err := dockerClient.Ping(); err != nil {
		c.HandleDockerError(fmt.Sprintf("Docker could not be reached at %s.  Docker must be installed and running to start containers.\n%v", dockerAddr, err))
		return
	}

	glog.Infof("Connecting to Docker at %s", dockerAddr)

	env, err := dockerClient.Version()
	if err != nil {
		c.HandleDockerError(fmt.Sprintf("Unable to check for Docker server version.\n%v", err))
		return
	}

	serverVersionString := env.Get("ApiVersion")
	serverVersion, err := dockerclient.NewAPIVersion(serverVersionString)
	if err != nil {
		c.HandleDockerError(fmt.Sprintf("Unable to determine Docker server version from %q.\n%v", serverVersionString, err))
		return
	}

	minimumPullByIDVersion, err := dockerclient.NewAPIVersion(minimumDockerAPIVersionWithPullByID)
	if err != nil {
		c.HandleDockerError(fmt.Sprintf("Unable to check for Docker server version.\n%v", err))
		return
	}

	if serverVersion.LessThan(minimumPullByIDVersion) {
		c.HandleDockerError(fmt.Sprintf("Docker 1.6 or later (server API version 1.18 or later) required."))
		return
	}

	c.DockerClient = dockerClient
}
