Terraform 无法启动 docker 服务

Question

我是第一次使用 Terraform 和 Packer。我正在尝试为内置 Docker 的 CentOS 创建 AWS AMI。从下面的加壳脚本中可以看出，我所做的只是运行执行 docker 文档中描述的一些 yum 命令，以便安装 docker。 =17=]

{
    "builders": [
    {
        "type": "amazon-ebs",
        "profile": "digital",
        "source_ami": "ami-061b1560",
        "instance_type": "t2.micro",
        "ssh_username": "centos",
        "ami_name": "centos-docker {{timestamp}}"
    }
],

"provisioners": [{
    "type": "shell",
    "inline": [
        "sleep 30",
        "sudo yum install -y yum-utils device-mapper-persistent-data lvm2",
        "sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo",
        "sudo yum makecache fast",
        "sudo yum install docker-ce"
    ]
}]

}

然后我在我的 terraform 脚本中使用上述脚本创建的 AMI，并添加 local-exec provisioner 以启动 docker 服务

provider "aws" {
   profile = "digital"
   region = "eu-west-1" 
}

resource "aws_instance" "chat-server" {
    ami = "ami-XXXXXX" 
    instance_type = "t2.micro"

    provisioner "local-exec" {
        command = "sudo systemctl start docker"
    }
}

当我运行 terraform apply 时，它会在试图启动 docker 服务的命令附近徘徊。

我在这里做错了什么？

您使用了错误的配置器，您应该使用 remote-exec。
