DockerFormula class

The built-in Docker formula: installs and manages the Docker engine.

Verify probes docker --version. Lifecycle actions use the platform's service manager / package manager. Install is idempotent (a host that already has Docker reports changed: false).

Methods

install(FormulaContext context) → Future<FormulaResult>

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

restart(FormulaContext context) → Future<FormulaResult>

Restarts the managed service.

inherited

run(FormulaAction action, FormulaContext context) → Future<FormulaResult>

Dispatches the given action to the matching method.

inherited

start(FormulaContext context) → Future<FormulaResult>

Starts the managed service.

inherited

status(FormulaContext context) → Future<FormulaStatusReport>

Present first, running second.

inherited

statusFrom(ExecResult result) → FormulaStatus

Maps a statusStepFor probe's outcome to a status.

inherited

statusStepFor(String osName) → CommandStep?

The daemon, not the CLI.

override

stepFor(FormulaAction action, String osName) → CommandStep?

Returns the command template for action on osName, or null if the action is unsupported on that platform.

override

stop(FormulaContext context) → Future<FormulaResult>

Stops the managed service.

inherited

toString() → String

A string representation of this object.

inherited

uninstall(FormulaContext context) → Future<FormulaResult>

Uninstalls the managed software.

inherited

update(FormulaContext context) → Future<FormulaResult>
