Variables ¶
var ( // ErrNotOutstanding is returned if an evaluation is not outstanding ErrNotOutstanding = errors.New("evaluation is not outstanding") // ErrTokenMismatch is the outstanding eval has a different token ErrTokenMismatch = errors.New("evaluation token does not match") // ErrNackTimeoutReached is returned if an expired evaluation is reset ErrNackTimeoutReached = errors.New("evaluation nack timeout reached") )
var ErrMultipleNamespaces = errors.New("multiple Vault namespaces requires Nomad Enterprise")
ErrMultipleNamespaces is send when multiple namespaces are used in the OSS setup
var MinVersionPlanNormalization = version.Must(version.NewVersion("0.9.2"))
MinVersionPlanNormalization is the minimum version to support the normalization of Plan in SubmitPlan, and the denormalization raft log entry committed in ApplyPlanResultsRequest
Functions ¶
func DefaultRPCAddr ¶
func NewConsulACLsAPI ¶ added in v0.10.4
func NewConsulACLsAPI(aclClient consul.ACLsAPI, logger hclog.Logger, purgeFunc PurgeSITokenAccessorFunc) *consulACLsAPI
func NewConsulConfigsAPI ¶ added in v0.12.4
func NewCoreScheduler ¶
func NewCoreScheduler(srv *Server, snap *state.StateSnapshot) scheduler.Scheduler
NewCoreScheduler is used to return a new system scheduler instance
func NewPeriodicHeap ¶ added in v0.3.0
func NewPeriodicHeap() *periodicHeap
func NewVaultClient ¶ added in v0.5.0
func NewVaultClient(c *config.VaultConfig, logger log.Logger, purgeFn PurgeVaultAccessorFn, delegate taskClientHandler) (*vaultClient, error)
NewVaultClient returns a Vault client from the given config. If the client couldn't be made an error is returned.
func NodeRpc ¶ added in v0.8.0
NodeRpc is used to make an RPC call to a node. The method takes the Yamux session for the node and the method to be called.
func NodeStreamingRpc ¶ added in v0.8.0
NodeStreamingRpc is used to make a streaming RPC call to a node. The method takes the Yamux session for the node and the method to be called. It conducts the initial handshake and returns a connection to be used or an error. It is the callers responsibility to close the connection if there is no error.
func PoliciesFrom ¶ added in v0.5.0
PoliciesFrom parses the set of policies returned by a token lookup.
func PolicyDataFrom ¶ added in v0.12.2
PolicyDataFrom parses the Data returned by a token lookup. It should not be used to parse TokenPolicies as the list will not be exhaustive.
func ServersMeetMinimumVersion ¶ added in v0.7.0
func ServersMeetMinimumVersion(members []serf.Member, region string, minVersion *version.Version, checkFailedServers bool) bool
ServersMeetMinimumVersion returns whether the Nomad servers are at least on the given Nomad version. The checkFailedServers parameter specifies whether version for the failed servers should be verified.
Types ¶
type ACL ¶ added in v0.7.0
type ACL struct {
// contains filtered or unexported fields
}
ACL endpoint is used for manipulating ACL tokens and policies
func (*ACL) Bootstrap ¶ added in v0.7.0

ConsulConfigsAPI is an abstraction over the consul/api.ConfigEntries API used by Nomad Server.
Nomad will only perform write operations on Consul Ingress/Terminating Gateway Configuration Entries. Removing the entries is not yet safe, given that multiple Nomad clusters may be writing to the same config entries, which are global in the Consul scope. There was a Meta field introduced which Nomad can leverage in the future, when Consul no longer supports versions that do not contain the field. The Meta field would be used to track which Nomad "owns" the CE. https://github.com/hashicorp/nomad/issues/8971

type EvalBroker ¶
type EvalBroker struct {
// contains filtered or unexported fields
}
EvalBroker is used to manage brokering of evaluations. When an evaluation is created, due to a change in a job specification or a node, we put it into the broker. The broker sorts by evaluations by priority and scheduler type. This allows us to dequeue the highest priority work first, while also allowing sub-schedulers to only dequeue work they know how to handle. The broker is designed to be entirely in-memory and is managed by the leader node.
The broker must provide at-least-once delivery semantics. It relies on explicit Ack/Nack messages to handle this. If a delivery is not Ack'd in a sufficient time span, it will be assumed Nack'd.
func NewEvalBroker ¶

NewEvalBroker creates a new evaluation broker. This is parameterized with the timeout used for messages that are not acknowledged before we assume a Nack and attempt to redeliver as well as the deliveryLimit which prevents a failing eval from being endlessly delivered. The initialNackDelay is the delay before making a Nacked evaluation available again for the first Nack and subsequentNackDelay is the compounding delay after the first Nack.

- Ack received: Unblock the evaluation allowing it to be dequeued
- Nack received: Drop the evaluation as it was created as a result of a scheduler run that was Nack'd
