示例1: updateAllMachines
// updateAllMachines finds all machines and resets the stored state address
// in each of them. The address does not include the port.
func updateAllMachines(st *state.State, stateAddr string) error {
machines, err := st.AllMachines()
if err != nil {
return err
}
pendingMachineCount := 0
done := make(chan error)
for _, machine := range machines {
// A newly resumed state server requires no updating, and more
// than one state server is not yet support by this plugin.
if machine.IsManager() || machine.Life() == state.Dead {
continue
}
pendingMachineCount++
machine := machine
go func() {
err := runMachineUpdate(machine, setAgentAddressScript(stateAddr))
if err != nil {
logger.Errorf("failed to update machine %s: %v", machine, err)
} else {
progress("updated machine %s", machine)
}
done <- err
}()
}
err = nil
for ; pendingMachineCount > 0; pendingMachineCount-- {
if updateErr := <-done; updateErr != nil && err == nil {
err = fmt.Errorf("machine update failed")
}
}
return err
}示例2: fetchMachines
// fetchMachines returns a map from top level machine id to machines, where machines[0] is the host
// machine and machines[1..n] are any containers (including nested ones).
//
// If machineIds is non-nil, only machines whose IDs are in the set are returned.
func fetchMachines(st *state.State, machineIds *set.Strings) (map[string][]*state.Machine, error) {
v := make(map[string][]*state.Machine)
machines, err := st.AllMachines()
if err != nil {
return nil, err
}
// AllMachines gives us machines sorted by id.
for _, m := range machines {
if machineIds != nil && !machineIds.Contains(m.Id()) {
continue
}
parentId, ok := m.ParentId()
if !ok {
// Only top level host machines go directly into the machine map.
v[m.Id()] = []*state.Machine{m}
} else {
topParentId := state.TopParentId(m.Id())
machines, ok := v[topParentId]
if !ok {
panic(fmt.Errorf("unexpected machine id %q", parentId))
}
machines = append(machines, m)
v[topParentId] = machines
}
}
return v, nil
}示例3: assertMachineCount
func assertMachineCount(c *gc.C, st *state.State, expect int) {
ms, err := st.AllMachines()
c.Assert(err, gc.IsNil)
c.Assert(ms, gc.HasLen, expect, gc.Commentf("%v", ms))
}
