CSI Hostpath driver

Usage:

Build hostpathplugin

$ make

Start Hostpath driver

$ sudo ./bin/hostpathplugin --endpoint tcp://127.0.0.1:10000 --nodeid CSINode -v=5

Test using csc

Get csc tool from https://github.com/rexray/gocsi/tree/master/csc

Get plugin info

$ csc identity plugin-info --endpoint tcp://127.0.0.1:10000
"csi-hostpath"  "0.1.0"

Create a volume

$ csc controller new --endpoint tcp://127.0.0.1:10000 --cap 1,block CSIVolumeName
CSIVolumeID

Delete a volume

$ csc controller del --endpoint tcp://127.0.0.1:10000 CSIVolumeID
CSIVolumeID

Validate volume capabilities

$ csc controller validate-volume-capabilities --endpoint tcp://127.0.0.1:10000 --cap 1,block CSIVolumeID
CSIVolumeID  true

NodePublish a volume

$ csc node publish --endpoint tcp://127.0.0.1:10000 --cap 1,block --target-path /mnt/hostpath CSIVolumeID
CSIVolumeID

NodeUnpublish a volume

$ csc node unpublish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/hostpath CSIVolumeID
CSIVolumeID

Get NodeInfo

$ csc node get-info --endpoint tcp://127.0.0.1:10000
CSINode

Types ¶

type Capacity ¶ added in v1.6.0

type Capacity map[string]resource.Quantity

Capacity simulates linear storage of certain types ("fast", "slow"). To calculate the amount of allocated space, the size of all currently existing volumes of the same kind is summed up.

Available capacity is configurable with a command line flag -capacity <type>=<size> where <type> is a string and <size> is a quantity (1T, 1Gi). More than one of those flags can be used.

The underlying map will be initialized if needed by Set, which makes it possible to define and use a Capacity instance without explicit initialization (`var capacity Capacity` or as member in a struct).

func (*Capacity) Enabled ¶ added in v1.6.0

func (c *Capacity) Enabled() bool

Enabled returns true if capacities are configured.

func (*Capacity) Set ¶ added in v1.6.0

func (c *Capacity) Set(arg string) error

Set is an implementation of flag.Value.Set.

func (*Capacity) String ¶ added in v1.6.0

func (c *Capacity) String() string

type Config ¶ added in v1.7.0

type Config struct {
	DriverName                 string
	Endpoint                   string
	ProxyEndpoint              string
	NodeID                     string
	VendorVersion              string
	StateDir                   string
	MaxVolumesPerNode          int64
	MaxVolumeSize              int64
	AttachLimit                int64
	Capacity                   Capacity
	Ephemeral                  bool
	ShowVersion                bool
	EnableAttach               bool
	EnableTopology             bool

	MaxVolumeExpansionSizeNode int64
	CheckVolumeLifecycle       bool
}

type ContainerFileSystem ¶ added in v1.5.0

type ContainerFileSystem struct {
	Children []MountPointInfo `json:"children"`
}

type FileSystems ¶ added in v1.5.0

type FileSystems struct {
	Filsystem []ContainerFileSystem `json:"filesystems"`
}

type MountPointInfo ¶ added in v1.5.0

type MountPointInfo struct {
	Target              string           `json:"target"`
	Source              string           `json:"source"`
	FsType              string           `json:"fstype"`
