Terraform:使用远程exec编辑文件

Question

我有一个使用terraform配置gomaster和GOServer的用例，然后使用新配置的GOMaster注册goserver。

以下是我正在使用的terraform食谱。Terraform也安装在docker服务器上，我从那里执行这个配方。

#Configure the Docker provider
    provider "docker" {
        host = "tcp://${var.dockerIP}:2376/"
    }

# Create the network
    resource "docker_network" "private_network" {
        name = "${var.customer_name}_network"
    }

     resource "docker_container" "goagent" {
         image = "${docker_image.goagent.latest}"
         name = "${var.customer_name}_goagent"
         hostname = "${var.customer_name}_goagent"
         command = [ "/bin/sh", "-c", "/usr/bin/supervisord" ]
         network_mode = "bridge"
         networks = [ "${docker_network.private_network.name}" ]
         provisioner "remote-exec" {
             connection {
                 user = "root"
                 password = "example"
             }
             inline = [
                  "sed -i -e 's/GO_SERVER=go-server/GO_SERVER=${var.customer_name}_goserver' /etc/defaut/go-agent",
                  "sed -i -e 's/DAEMON=N/DAEMON=Y' /etc/defaut/go-agent",
                  "/etc/init.d/go-agent restart"
             ]
        }
     }

# Create a container
    resource "docker_container" "goservertest" {
    image = "${docker_image.goserver.latest}"
    name = "${var.customer_name}_goserver"
    hostname = "${var.customer_name}_goserver"
    network_mode = "bridge"
    networks = [ "${docker_network.private_network.name}" ]
    ports{
        internal = "8153"
    external = "8003"
    }
    ports{
    internal = "8154"
        external = "8002"    
    }
}

resource "docker_image" "goserver" {
    name = "gocd/gocd-server:latest"
}

resource "docker_image" "goagent" {
name = "gocd/gocd-agent:latest"
}

goagent资源中的远程exec部分不工作。我的假设是它登录到预置的goagent，并根据指定的sed命令修改其中的文件。相反，它正在对docker host执行ssh并修改文件。我是不是遗漏了什么？我们是否必须在远程设备的连接块中指定in地址或主机名？
