type CSITopology

type CSITopology struct {
	Segments map[string]string
}

CSITopology is a map of topological domains to topological segments. A topological domain is a sub-division of a cluster, like "region", "zone", "rack", etc.

According to CSI, there are a few requirements for the keys within this map:

  • Valid keys have two segments: an OPTIONAL prefix and name, separated by a slash (/), for example: "com.company.example/zone".
  • The key name segment is REQUIRED. The prefix is OPTIONAL.
  • The key name MUST be 63 characters or less, begin and end with an alphanumeric character ([a-z0-9A-Z]), and contain only dashes (-), underscores (_), dots (.), or alphanumerics in between, for example "zone".
  • The key prefix MUST be 63 characters or less, begin and end with a lower-case alphanumeric character ([a-z0-9]), contain only dashes (-), dots (.), or lower-case alphanumerics in between, and follow domain name notation format (https://tools.ietf.org/html/rfc1035#section-2.3.1).
  • The key prefix SHOULD include the plugin's host company name and/or the plugin name, to minimize the possibility of collisions with keys from other plugins.
  • If a key prefix is specified, it MUST be identical across all topology keys returned by the SP (across all RPCs).
  • Keys MUST be case-insensitive. Meaning the keys "Zone" and "zone" MUST not both exist.
  • Each value (topological segment) MUST contain 1 or more strings.
  • Each string MUST be 63 characters or less and begin and end with an alphanumeric character with '-', '_', '.', or alphanumerics in between.

However, Nomad applies lighter restrictions to these, as they are already only referenced by plugin within the scheduler and as such collisions and related concerns are less of an issue. We may implement these restrictions in the future.

AddAllocs is used to add the used network resources. Returns true if there is a collision

AddAllocs may be called multiple times for the same NetworkIndex with UsedPorts cleared between calls (by Release). Therefore AddAllocs must be determistic and must not manipulate state outside of UsedPorts as that state would persist between Release calls.

func (idx *NetworkIndex) SetNode(node *Node) error

SetNode is used to initialize a node's network index with available IPs, reserved ports, and other details from a node's configuration and fingerprinting.

SetNode must be idempotent as preemption causes SetNode to be called multiple times on the same NetworkIndex, only clearing UsedPorts between calls.

An error is returned if the Node cannot produce a consistent NetworkIndex such as if reserved_ports are unparseable.

Any errors returned by SetNode indicate a bug! The bug may lie in client code not properly validating its configuration or it may lie in improper Node object handling by servers. Users should not be able to cause SetNode to error. Data that cause SetNode to error should be caught upstream such as a client agent refusing to start with an invalid configuration.

type VolumeMount

type VolumeMount struct {
	Volume          string
	Destination     string
	ReadOnly        bool
	PropagationMode string

type WaitConfig

type WaitConfig struct {
	Min *time.Duration
	Max *time.Duration
}

WaitConfig is the Min/Max duration used by the Consul Template Watcher. Consul Template relies on pointer based business logic. This struct uses pointers so that we tell the different between zero values and unset values.

func (*WaitConfig) Copy

Copy returns a deep copy of this configuration.

func (*WaitConfig) Equal

func (wc *WaitConfig) Equal(o *WaitConfig) bool

func (*WaitConfig) Validate

func (wc *WaitConfig) Validate() error

Validate that the min is not greater than the max

type WrappedServerError

type WrappedServerError struct {

func (r *WrappedServerError) IsServerSide() bool

type WriteMeta

type WriteMeta struct {
	// This is the index associated with the write
	Index uint64
}

WriteMeta allows a write response to include potentially useful metadata about the write

type WriteRequest

type WriteRequest struct {
	// The target region for this write
	Region string

	// Namespace is the target namespace for the write.
	//
	// Since RPC handlers do not have a default value set they should
	// access the Namespace via the RequestNamespace method.
	//
	// Requests accessing specific namespaced objects must check ACLs
	// against the namespace of the object, not the namespace in the
	// request.
	Namespace string

	// AuthToken is secret portion of the ACL token used for the request
	AuthToken string

	// IdempotencyToken can be used to ensure the write is idempotent.
	IdempotencyToken string

	// contains filtered or unexported fields
}

func (WriteRequest) AllowStaleRead

func (w WriteRequest) AllowStaleRead() bool

func (WriteRequest) GetIdentity

func (w WriteRequest) GetIdentity() *AuthenticatedIdentity

func (WriteRequest) IsRead

func (w WriteRequest) IsRead() bool

IsRead only applies to writes, always false.

func (WriteRequest) RequestNamespace

func (w WriteRequest) RequestNamespace() string

RequestNamespace returns the request's namespace or the default namespace if no explicit namespace was sent.

Requests accessing specific namespaced objects must check ACLs against the namespace of the object, not the namespace in the request.
