示例1: ConfigureScript
// ConfigureScript generates the bash script that applies
// the specified cloud-config.
func ConfigureScript(cloudcfg *cloudinit.Config) (string, error) {
if cloudcfg == nil {
panic("cloudcfg is nil")
}
// TODO(axw): 2013-08-23 bug 1215777
// Carry out configuration for ssh-keys-per-user,
// machine-updates-authkeys, using cloud-init config.
//
// We should work with smoser to get a supported
// command in (or next to) cloud-init for manually
// invoking cloud-config. This would address the
// above comment by removing the need to generate a
// script "by hand".
// Bootcmds must be run before anything else,
// as they may affect package installation.
bootcmds, err := cmdlist(cloudcfg.BootCmds())
if err != nil {
return "", err
}
// Depending on cloudcfg, potentially add package sources and packages.
pkgcmds, err := addPackageCommands(cloudcfg)
if err != nil {
return "", err
}
// Runcmds come last.
runcmds, err := cmdlist(cloudcfg.RunCmds())
if err != nil {
return "", err
}
// We prepend "set -xe". This is already in runcmds,
// but added here to avoid relying on that to be
// invariant.
script := []string{"#!/bin/bash", "set -e"}
// We must initialise progress reporting before entering
// the subshell and redirecting stderr.
script = append(script, cloudinit.InitProgressCmd())
stdout, stderr := cloudcfg.Output(cloudinit.OutAll)
script = append(script, "(")
if stderr != "" {
