type CSITopology added in v0.11.0 

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.

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 WriteMeta 

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

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.
