Types

type MasterConfig

type MasterConfig struct {
	MasterIP    net.IP
	MasterPort  int
	MasterCount int

	NodeHosts []string
	PortalNet *net.IPNet

	RequestContextMapper kapi.RequestContextMapper

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

	Authorizer       authorizer.Authorizer
	AdmissionControl admission.Interface

	SchedulerConfigFile string
}

MasterConfig defines the required values to start a Kubernetes master

func BuildKubernetesMasterConfig added in v0.4.2

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) RunMinionController added in v0.2.1

func (c *MasterConfig) RunMinionController()

func (*MasterConfig) RunNamespaceController added in v0.4.3

func (c *MasterConfig) RunNamespaceController()

func (*MasterConfig) RunPersistentVolumeClaimBinder added in v0.5.2

func (c *MasterConfig) RunPersistentVolumeClaimBinder()

func (*MasterConfig) RunReplicationController

func (c *MasterConfig) RunReplicationController()

RunReplicationController starts the Kubernetes replication controller sync loop

func (*MasterConfig) RunResourceQuotaManager added in v0.3.2

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 name of this node that will be used to identify the node in the master.
	// This value must match the value provided to the master on startup.
	NodeHost string
	// The host that the master can be reached at (not in use yet)
	MasterHost string
	// The directory that volumes will be stored under
	VolumeDir string

	ClusterDomain string
	ClusterDNS    net.IP

	// a function that returns the appropriate image to use for a named component
	ImageFor func(component string) string

	// The name of the network plugin to activate
	NetworkPluginName string

	// If true, the Kubelet will ignore errors from Docker
	AllowDisabledDocker bool

	// Whether to enable TLS serving
	TLS bool

	// Enable TLS serving
	KubeletCertFile string
	KubeletKeyFile  string

	// ClientCAs will be used to request client certificates in connections to the node.
	// This CertPool should contain all the CAs that will be used for client certificate verification.
	ClientCAs *x509.CertPool

	// A client to connect to the master.
	Client *client.Client
	// A client to connect to Docker
	DockerClient dockertools.DockerInterface

	// PodManifestPath specifies the path for the pod manifest file(s)
	// The path could point to a single file or a directory that contains multiple manifest files
	// This is used by the Kubelet to create pods on the node
	PodManifestPath string
	// PodManifestCheckIntervalSeconds is the interval in seconds for checking the manifest file(s) for new data
	// The interval needs to be a positive value
	PodManifestCheckIntervalSeconds int64
}

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

func BuildKubernetesNodeConfig added in v0.4.2

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 added in v0.5.1

func (c *NodeConfig) HandleDockerError(message string)

HandleDockerError handles an an error from the docker daemon

func (*NodeConfig) RunKubelet

type ProxyConfig struct {
	ClientConfig *kclient.Config
}

func (*ProxyConfig) InstallAPI added in v0.2.2

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