Overview

Package phase is all the various phases used for bootstrapping a cluster. The phase files are named in a rough order used during an install; - 0x are for preconnection resources, along with ssh-ing into the node - 1x are used to gather information about the nodes in the cluster - 2x are for modifying host services, like firewalls, host files, and enabling kernel level modules - 5x are for staging files for the distro engine, e.i. rpm's, apt's, or binary files - 6x are for starting the engine or for upgrading an existing install - 8x are for resetting the engine from the nodes - 9x are last minute things and finally disconnecting from a node - ext are files that are currently not used but may be incorporated later

Variables

View Source 
var ErrNoControllers = errors.New("no controllers are running")

ErrNoControllers an error for when no controllers are running

View Source 
var ErrNoKubeConfig = errors.New("kubeconfig has not been built")

ErrNoKubeConfig is returned when the config is asked for before the phase has run

View Source 
var ErrUnmanagedNodes = errors.New("the cluster holds nodes the config does not: add the host back to the config, run `cargoship install reset` against it, or pass --allow-unmanaged-nodes to apply anyway")

ErrUnmanagedNodes is returned when the cluster holds a node no host in the config accounts for. Apply removes nothing, so continuing would report success over a machine that is still running the engine and still joined.

var (
	// Interval is the time to wait between retry attempts

var NoWait bool

NoWait is used by various phases to decide if node ready state should be waited for or not

Functions

func DryRunNote 

func DryRunNote(p Phase) string

DryRunNote returns the phase's own account of why a dry run runs it, or "" for a phase that gives none. Only read-only phases carry one: they are the phases a dry run runs against live hosts, so they are the ones a reader is entitled to an argument about.

func Titles 

func Titles(results []PhaseResult) []string

Titles names the phases in a slice, for a caller that reports a list of names rather than the detail behind them.

type DetectRemovedHosts 

type DetectRemovedHosts struct {
	GenericPhase
	Distro distrocfg.Distro
	// AllowUnmanaged downgrades the refusal to a warning. A cluster can hold nodes cargoship
	// never joined, and refusing on those would block every apply on a working setup, so the
	// operator needs a way to say the extra nodes are deliberate.
	AllowUnmanaged bool
	// contains filtered or unexported fields
}

DetectRemovedHosts state.

Apply drives the cluster towards the config, but only ever forwards: every phase after this one reads Spec.Hosts and acts on what it finds there. A host deleted from the config is therefore invisible to all of them, and the machine keeps running the engine and stays joined to the cluster while apply reports success. This phase is what stops that from being silent.

It detects and refuses. It does not reconcile, and the reason is not effort: apply cannot reach the machine it would have to clean up. Draining a node and deleting its Node object needs only the name, which the API gives us. Uninstalling the engine needs an SSH connection, and the address, user and key for that lived in the host block that was just deleted. Deleting the Node object without the uninstall is worse than doing nothing, because it looks like the removal worked while the machine keeps its certificates and tries to rejoin -- and for a controller it stays an etcd member, so the quorum arithmetic silently moves against a member nobody can reach.

The layer that does hold the connection details for a removed host is the OpenTofu provider, which still has the old host block in its state file when it plans the destroy. That is where a real removal path belongs, and it can call reset against exactly that host. Until then this phase makes the gap loud instead of invisible.

func (*DetectRemovedHosts) Explanation 

func (p *DetectRemovedHosts) Explanation() string

Explanation about the current phase, used for documentation generation

func (*DetectRemovedHosts) Prepare 

func (p *DetectRemovedHosts) Prepare(ctx context.Context, _ *cluster.ZarfCluster, _ *distro.ZarfDistro) error

Prepare the phase.

The leader is any host in the config already running the controller service, which is the same way the label and delete phases find one. Nothing is running on a first install, so there is no leader, and ShouldRun turns the phase off: a cluster that does not exist yet cannot have had a host removed from it.

func (*DetectRemovedHosts) ReadOnly 

func (p *DetectRemovedHosts) ReadOnly() string

ReadOnly marks this phase safe under a dry run, and returns the reason for the phase docs.

func (*DetectRemovedHosts) Run 

func (p *DetectRemovedHosts) Run(ctx context.Context) error

Run the phase.

Only positive evidence stops the apply. Failing to reach the cluster says nothing about whether a host was removed, and this phase runs before every phase that does the real work, so treating an unreachable cluster as a refusal would turn a transient failure into a failed apply that had nothing to do with removals. Those cases warn and continue.

func (*DetectRemovedHosts) ShouldRun

ShouldRun is true once there is a running controller to ask

func (p *Disconnect) Title() string

Title for the phase

type DryRunBehavior 

type DryRunBehavior int

DryRunBehavior is what a dry run does with a phase. It is derived from the interfaces the phase implements, and it is exported so magefiles/gen-docs.go can label each phase in docs/phases/<name>.md with the same classification Run() gates on. The docs and the gate cannot disagree, because there is only one classifier. 

const (
	// DryRunSkip is the default: the phase declares nothing, so a dry run reports it and
	// does not run it.
	DryRunSkip DryRunBehavior = iota
	// DryRunReadOnly is a phase implementing readOnly. It reads hosts and changes nothing,
	// so a dry run runs it as itself.
	DryRunReadOnly
	// DryRunOwnPath is a phase implementing withDryRun. A dry run calls DryRun() instead of
	// Run().
	DryRunOwnPath
)

}

EngineConfigSyncHosts phase state

func (*EngineConfigSyncHosts) Changed 

func (p *EngineConfigSyncHosts) Changed() bool

Changed reports whether this phase altered any host, which is what Ansible's changed is built from. See changedReporter in 05_manager.go.

There are two ways this phase changes a host and both count. The obvious one is the sync itself. The other is the file a host carries that the engine re-reads without a restart: that is written while Prepare is deciding which hosts have drifted, and the host is then not listed as needing a sync, so a run that changed only those files would otherwise read as a run that did nothing.

func (*EngineConfigSyncHosts) ShouldRun

type ResultSink 

type ResultSink struct {
	// contains filtered or unexported fields
}

ResultSink collects the RunResult of every Manager.Run that happens on a context.

It exists because the Ansible module mode runs cargoship by building an argument vector and calling the ordinary command, which returns an error and nothing else -- see src/cmd.ExecuteArgs. Threading a return value back through cobra, the action and the manager would change five call sites to serve one caller. A sink on the context that nobody else installs does not, and a run with no sink on its context pays nothing for this.

func WithResultSink 

func WithResultSink(ctx context.Context) (context.Context, *ResultSink)

WithResultSink returns a context carrying a sink, and the sink itself.

func (*ResultSink) Observed 

func (s *ResultSink) Observed() bool

Observed reports whether any run reached its phases at all. A command that failed before that -- an unreadable package, a configuration that does not validate -- publishes nothing, and that is a different thing from a run in which no phase changed anything.

func (*ResultSink) Result 

func (s *ResultSink) Result() RunResult

Result is every run that reached its phases on this context, flattened into one.

type RunResult 

type RunResult struct {
	// Ran are the phases that executed, in order. That includes the read-only phases a dry run
	// runs as themselves and the phases that took their own dry-run path. Running is not
	// changing: Connect, DetectOS, GatherFacts and ValidateHosts all land here and change
	// nothing, which is why Changed is asked separately.
	Ran []PhaseResult
	// Planned are the phases a dry run reported instead of running.
	Planned []PhaseResult
	// Skipped are the phases ShouldRun filtered out. They are kept because a phase can finish
	// its work in Prepare and then have nothing left to run: EngineConfigSyncHosts writes the
	// files the engine re-reads without a restart while it is deciding which hosts have
	// drifted, and then reports no hosts to sync.
	Skipped []PhaseResult
}

RunResult is what a whole Manager.Run did, phase by phase. Manager.Run fills it in on the way through, so a run that returned an error still carries the phases it got through first.

func (RunResult) Changed 

func (r RunResult) Changed() bool

Changed reports whether any phase said it changed something on the fleet. Phases that declared nothing do not contribute; read Complete to find out whether that leaves the answer partial.

func (RunResult) Complete 

func (r RunResult) Complete() bool

Complete reports whether every phase the run reached declared whether it changed anything.

func (RunResult) Outstanding 

func (r RunResult) Outstanding() bool

Outstanding is the dry-run counterpart of Changed: it reports whether any phase that can report a change was reported rather than run. A phase reaches Planned only after its ShouldRun said there was work to do, so this answers "would a real run change anything" for the phases that have said how to tell.

func (RunResult) Undeclared 

func (r RunResult) Undeclared() []string

Undeclared names the phases that did not say whether they changed anything, in the order the run reached them. A caller reporting Changed is expected to report these alongside it.
