Functions ¶
func NewChecks ¶
func NewChecks(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewChecks returns executor that executes preflight checks on the node.
func NewClusterPackages ¶
func NewClusterPackages(p fsm.ExecutorParams, operator ops.Operator, localPackages pack.PackageService) (fsm.PhaseExecutor, error)
NewClusterPackages returns executor that updates packages in the cluster state.
Specifically, it updates the certificate authority package stored in the cluster state with the one newly generated during the configure phase from the local state.
func NewDirectories ¶
func NewDirectories(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewDirectories returns executor that cleans up directories on the node.
Specifically, it removes the directories where Teleport node and auth server keep their data so they regenerate their secrets upon startup.
func NewEtcd ¶
func NewEtcd(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewEtcd returns executor that updates etcd member with new advertise URL.
func NewGravity ¶
func NewGravity(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewGravity returns executor that waits for gravity-site to become available.
func NewNetwork ¶
func NewNetwork(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewNetwork returns executor that cleans up network interfaces on the node.
func NewNode ¶
func NewNode(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewNode returns executor that removes old Kubernetes node object.
func NewPackages ¶
func NewPackages(p fsm.ExecutorParams, operator ops.Operator, packages pack.PackageService) (fsm.PhaseExecutor, error)
NewPackages returns executor that removes old packages on the node.
Specifically, it removes configuration and secret packages left from the original installation from the node local state.
func NewPods ¶
func NewPods(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewPods returns executor that removes old Kubernetes pods.
All Kubernetes pods have to be recreated when the cluster comes up after reconfiguration to ensure that no old pods are lingering (Kubernetes may get confused after the old node is gone and keep pods in terminating state for a long time) and that they mount proper service tokens.
func NewRestart ¶
func NewRestart(p fsm.ExecutorParams, operator ops.Operator, packages pack.PackageService) (fsm.PhaseExecutor, error)
NewRestart returns executor that restarts systemd unit for the specified package.
func NewState ¶
func NewState(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewState returns executor that updates the cluster state.
This phase patches the cluster state with updated node/cluster information and also removes old certificate authorities to make sure they are regenerated when teleport auth server starts up.
func NewTokens ¶
func NewTokens(p fsm.ExecutorParams, operator ops.Operator) (fsm.PhaseExecutor, error)
NewTokens returns executor that removes old service account tokens.
During the reconfigure operation, the secrets get regenerated thus invalidating old service account tokens. Kubernetes will recreate them automatically when they are deleted during this phase.
