第 5 章 Running first-boot commands by using cloud-init

• The bootcmd section executes early in the initialization process and by default runs on every boot.
• The runcmd section executes near the end of the process and is only executed during the first boot and initialization.

Prerequisites

• Depending on the requirements of your datasource, edit the user-data file or add the following directive to the cloud.cfg.d directory:

  注意

  All user directives include #cloud-config at the top of the file so that cloud-init recognizes the file as containing user directives. When you include directives in the cloud.cfg.d directory, name the file *.cfg, and always include #cloud-config at the top of the file.
