TODO (manadart 2021-05-18): These are exported for tests and in the case of the timeout, for feature tests. That especially should be a dependency of the worker.
Functions ¶
func Manifold ¶
func Manifold(config ManifoldConfig) dependency.Manifold
Manifold returns a dependency manifold that runs an upgrader worker, using the resource names defined in the supplied config.
func NewLock ¶
NewLock creates a gate.Lock to be used to synchronise workers which need to start after upgrades have completed. The returned Lock should be passed to NewWorker. If the agent has already upgraded to the current version, then the lock will be returned in the released state.
func NewWorker ¶
func NewWorker( upgradeComplete gate.Lock, agent agent.Agent, apiConn api.Connection, isController bool, openState func() (*state.StatePool, error), preUpgradeSteps upgrades.PreUpgradeStepsFunc, retryStrategy retry.CallArgs, entity StatusSetter, isCaas bool, ) (worker.Worker, error)
NewWorker returns a new instance of the upgradeSteps worker. It will run any required steps to upgrade to the currently running Juju version.
Types ¶
type ManifoldConfig ¶
type ManifoldConfig struct {
AgentName string
APICallerName string
UpgradeStepsGateName string
OpenStateForUpgrade func() (*state.StatePool, error)
PreUpgradeSteps upgrades.PreUpgradeStepsFunc
NewAgentStatusSetter func(apiConn api.Connection) (StatusSetter, error)
}
ManifoldConfig defines the names of the manifolds on which a Manifold will depend.
