我正在尝试使用多部分配置运行一些脚本和配置。

docker pull rancher/server:v1.0.2

问题在于脚本的执行顺序... - 首先 yum 安装脚本 - 然后是 bash 脚本 - 然后是runcmd脚本
那么当执行用户脚本命令时，docker 服务还没有启动
我在 EC2 上使用 Amazon Linux AMI，它是 CentOS...
这是云初始化日志

来自 irc #cloud-init 的 @smoser 帮助了我
查看/var/lib/cloud/instance/scripts/
您会看到一个文件被命名runcmd
，并且多部分中的其他文件都由它们的文件名命名。
该目录中的脚本按 C 语言环境排序顺序运行（就像通过 runparts 运行一样）
因此，如果您将所添加的脚本的名称更改为，
filename="00-rancher_server_install"
那么
filename="zz-rancher_server_install"
就很好了。
