Types

type MasterConfig

type MasterConfig struct {
	Options configapi.KubernetesMasterConfig

	MasterPort int

	// TODO: remove, not used
	PortalNet *net.IPNet

	RequestContextMapper kapi.RequestContextMapper

	EtcdHelper          tools.EtcdHelper
	KubeClient          *kclient.Client
	KubeletClientConfig *kclient.KubeletConfig

	Authorizer       authorizer.Authorizer
	AdmissionControl admission.Interface
}

MasterConfig defines the required values to start a Kubernetes master

func BuildKubernetesMasterConfig

func BuildKubernetesMasterConfig(options configapi.MasterConfig, requestContextMapper kapi.RequestContextMapper, kubeClient *kclient.Client) (*MasterConfig, error)

func (*MasterConfig) EnsurePortalFlags

func (c *MasterConfig) EnsurePortalFlags()

TODO: Longer term we should read this from some config store, rather than a flag.

func (*MasterConfig) InstallAPI

func (c *MasterConfig) InstallAPI(container *restful.Container) []string

InstallAPI starts a Kubernetes master and registers the supported REST APIs into the provided mux, then returns an array of strings indicating what endpoints were started (these are format strings that will expect to be sent a single string value).

func (*MasterConfig) RunEndpointController

func (c *MasterConfig) RunEndpointController()

RunEndpointController starts the Kubernetes replication controller sync loop

func (*MasterConfig) RunNamespaceController

func (c *MasterConfig) RunNamespaceController()

func (*MasterConfig) RunNodeController

func (c *MasterConfig) RunNodeController()

func (*MasterConfig) RunPersistentVolumeClaimBinder

func (c *MasterConfig) RunPersistentVolumeClaimBinder()

func (*MasterConfig) RunReplicationController

func (c *MasterConfig) RunReplicationController()

RunReplicationController starts the Kubernetes replication controller sync loop

func (*MasterConfig) RunResourceQuotaManager

func (c *MasterConfig) RunResourceQuotaManager()

func (*MasterConfig) RunScheduler

func (c *MasterConfig) RunScheduler()

RunScheduler starts the Kubernetes scheduler

type NodeConfig

type NodeConfig struct {
	// The address to bind to
	BindAddress string
	// The directory that volumes will be stored under
	VolumeDir string
	// If true, the Kubelet will ignore errors from Docker
	AllowDisabledDocker bool
	// A client to connect to the master.
	Client *client.Client
	// A client to connect to Docker
	DockerClient dockertools.DockerInterface

	// The KubeletServer configuration
	KubeletServer *kapp.KubeletServer
	// The configuration for the kubelet, fully initialized
	KubeletConfig *kapp.KubeletConfig
}

NodeConfig represents the required parameters to start the OpenShift node through Kubernetes. All fields are required.

func BuildKubernetesNodeConfig

func BuildKubernetesNodeConfig(options configapi.NodeConfig) (*NodeConfig, error)

func (*NodeConfig) EnsureDocker

func (c *NodeConfig) EnsureDocker(docker *dockerutil.Helper)

EnsureDocker attempts to connect to the Docker daemon defined by the helper, and if it is unable to it will print a warning.

func (*NodeConfig) EnsureVolumeDir

func (c *NodeConfig) EnsureVolumeDir()

EnsureVolumeDir attempts to convert the provided volume directory argument to an absolute path and create the directory if it does not exist. Will exit if an error is encountered.

func (*NodeConfig) HandleDockerError

func (c *NodeConfig) HandleDockerError(message string)

HandleDockerError handles an an error from the docker daemon

func (*NodeConfig) RunKubelet

func (c *NodeConfig) RunKubelet()

RunKubelet starts the Kubelet.

func (*NodeConfig) RunProxy

func (c *NodeConfig) RunProxy()

RunProxy starts the proxy

type ProxyConfig

type ProxyConfig struct {
	ClientConfig *kclient.Config
}

func (*ProxyConfig) InstallAPI

func (c *ProxyConfig) InstallAPI(container *restful.Container) []string
