Question

现在我正在尝试学习Terraform并开始在docker容器中使用它。我想制作一个灯堆。所以要求如下

MySQL - 单独的容器
- 端口 - 3306需要转发给主机8080
PHP / Apache - 单独的容器
- 端口 - 80需要转发到主机8080
Nginx as Proxy - 单独的容器
- 端口 - 80需要转发到主机80

以下是此要求的代码：

vi main.tf

module "db_server_vm" {
  source    = "./module"
  server_name  = "db-server"
  servers      = "1"
}

module "app_server_vm" {
  source    = "./module"
  server_name  = "app-server"
  servers      = "1"
}

module "proxy_server_vm" {
   source    = "./module"
   server_name  = "proxy-server"
   servers      = "1"
}

模块文件如下：

vi module/docker_container.tf

variable "container_image" {
   type = "string"
   default = "containers.dev.int/redhat:6.7_latest"
}

resource "docker_container" "container" {
    image = "${var.container_image}"
    name = "${var.server_name}-${count.index}"
    hostname = "${var.server_name}"
    domainname = "example.int"
    count = "${var.servers}"
    must_run = true
    restart = "always" 
    privileged = true
    env = ["env=test", "role=test"]

    command = ["/usr/sbin/sshd", "-D", "-o", "UseDNS=no", "-o", "PasswordAuthentication=yes", "-o", "UsePrivilegeSeparation=no", "-o", "UsePAM=no", "-o", "PidFile=/tmp/sshd.pid"]
    }

使用上面我能够创建容器，但现在我很困惑如何将逻辑转发给主机vm的相关端口。再次如何为容器分配静态IP？因为我要求IP使用应用程序配置数据库，使用应用程序配置代理

使用Terraform
