Azure 容器组 2 个容器，带有 2 个外部端口。第二个容器总是终止

Question

我正在尝试部署具有多个外部端口的 Azure 容器实例。我尝试了以下地形代码：

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "experiment" {
  name     = "experiment"
  location = "west europe"
}

resource "azurerm_container_group" "nginx" {
  name                = "nginx-test-terraform"
  location            = azurerm_resource_group.experiment.location
  resource_group_name = azurerm_resource_group.experiment.name
  os_type             = "Linux"
  ip_address_type     = "public"
  dns_name_label      = "nginx-test-terraform"

  container {
    name   = "nginx"
    image  = "nginx"
    cpu    = "0.5"
    memory = "0.5"
    ports {
      port     = 80
      protocol = "TCP"
    }
  }

  container {
    name   = "nginx2"
    image  = "nginx"
    cpu    = "0.5"
    memory = "0.5"
    ports {
      port     = 81
      protocol = "TCP"
    }
  }
}

但是，第二个容器总是失败并出现以下错误：

[emerg] 1#1: bind() 到 0.0.0.0:80 失败（98：地址已被使用）

我是否可以在文件中更正此问题，或者这是目前 Terraform 的限制？

我对 Yaml 文件进行了同样的尝试：

apiVersion: 2018-10-01
name: dockercompose-exp-01
location: westeurope
type: Microsoft.ContainerInstance/containerGroups
properties:
  osType: Linux
  restartPolicy: Always
  containers:
  - name: helloworld-ms
    properties:
      image: mcr.microsoft.com/azuredocs/aci-helloworld
      resources:
        requests:
          cpu: 0.5
          memoryInGB: 0.5
      ports:
      - port: 80
        protocol: TCP
  - name: helloworld-nginx
    properties:
      image: nginx
      resources:
        requests:
          cpu: 0.5
          memoryInGB: 0.5
      ports:
      - port: 81
        protocol: TCP
  ipAddress:
    ports:
    - port: 80
      protocol: TCP
    - port: 81
      protocol: TCP
    type: Public
    dnsNameLabel: dockercompose-exp-01

同样的事情发生了。

因此，这似乎是平台的限制，或者我遇到了某种语法错误。

如有任何帮助，我们将不胜感激。

实际上，ACI不支持端口映射。您只能直接公开端口。而且端口是独一无二的。

所以你犯的错误是Nginx镜像在Dockerfile中暴露了80端口，而你想为第二个暴露81端口。然后81端口无法响应。我建议不要在一个容器组中部署同一个镜像，没用的。
