16.04：如何从 cloud-init 编写和运行 bash shell 脚本？

Question

我正在编写以下 cloud-init 文件，该文件将在 OpenStack 中部署 VM 时执行：

#cloud-config
password: passwword
chpasswd: { expire: False }
ssh_pwauth: True

write_files:
-   content: |
        This is the write_files and should be line 1 of 2

    path: /home/ubuntu/file.txt

-   content: |
        echo "This is the runcmd and should be line 3 of 3" >> /home/ubuntu/file.txt

    owner: root:root
    permissions: '755'
    path: /home/ubuntu/bin/test

runcmd:
  - echo "This is the runcmd and should be line 2 of 2" >> /home/ubuntu/file.txt
  - test

VM启动后，输出为cat file.txt：

This is the write_files and should be line 1 of 2
This is the runcmd and should be line 2 of 2 

cloud-init因此，不会执行运行名为 的 shell 脚本的最后一行，test该脚本会写入file.txt..

我究竟做错了什么 ？！

我猜这/home/ubuntu/bin/不在 PATH 中。尝试/home/ubuntu/bin/test在runcmd
