2.4. 使用 OSTree 系统的 systemd 自动化集成过程

流程

1. 使用以下示例创建蓝图文件：

   [[customizations.files]]
   path = "/usr/lib/systemd/system/microshift.service.d/10-auto-recovery.conf"
   data = """
   [Unit]
   OnFailure=microshift-auto-recovery.service
   """
   
   [[customizations.files]]
   path = "/usr/lib/systemd/system/microshift-auto-recovery.service"
   data = """
   [Unit]
   Description=MicroShift auto-recovery
   
   [Service]
   Type=oneshot
   ExecStart=/usr/bin/microshift-auto-recovery
   
   [Install]
   WantedBy=multi-user.target
   """
   
   [[customizations.files]]
   path = "/usr/bin/microshift-auto-recovery"
   mode = "0755"
   data = """
   #!/usr/bin/env bash
   set -xeuo pipefail
   
   # If greenboot uses a non-default file for clearing boot_counter, use boot_success instead.
   if grep -q  "/boot/grubenv" /usr/libexec/greenboot/greenboot-grub2-set-success; then
       if grub2-editenv - list | grep -q ^boot_success=0; then
           echo "Greenboot didn't decide the system is healthy after staging a new deployment."
           echo "Quitting to not interfere with the process"
           exit 0
       fi
   else
       if grub2-editenv - list | grep -q ^boot_counter=; then
           echo "Greenboot didn't decide the system is healthy after staging a new deployment."
           echo "Quitting to not interfere with the process"
           exit 0
       fi
   fi
   
   /usr/bin/microshift restore --auto-recovery /var/lib/microshift-auto-recovery
   /usr/bin/systemctl reset-failed microshift
   /usr/bin/systemctl start microshift
   
   echo "DONE"
   """
