How to expose multiple ports on Azure Container Instance?

Question

Is it possible to expose/open more than one port on an Azure Container Instance? I've only been able to open one port per container.

I'd like to run the equivalent of: docker run -p 80:80 -p 443:443 ...

I've unsuccessfully tried:

• Maps only the last port: az container create ... --port 80 --port 443
• Syntax error: az container create ... --port 80 443

But the resource JSON seems to indicate that an array is possible:

az container show -name <container-name> --resource-group <resource-group-name>

Response: 
{
  "containers": [
    {
      ...
      "name": "...",
      "ports": [
        {
          "port": 80
        }
      ...
    }
  ],
   ...
  "ipAddress": {
    "ip": "xxx.xxx.xxx.xxx",
    "ports": [
      {
        "port": 80,
        "protocol": "TCP"
      }
    ]
  },
  ...
}

Answer 1

This can now be done via Azure CLI. Example is below:

az container create -g MyResourceGroup --name myalpine --image alpine:latest --ip-address public --ports 80 443

https://learn.microsoft.com/en-us/cli/azure/container?view=azure-cli-latest#az_container_create

**update: you can set the protocol now as well. TCP or UDP in both the cli and the portal.

i.e.

[--ports]
[--protocol {TCP, UDP}]

Now Azure Portal provides way to add two extra ports. All you need is to say "Yes" to Open additional ports in Configuration while creating ACI. See Image below.

Answer 3

You can, but currently you can only do it with an Azure Resource Manager template. The CLI and the portal are both oriented towards the simple case: one container in the container group, and one exposed port in that container.

Here's an example resources section from an Azure Resource Manager template (see full template):

"resources": [
{
        "name": "myContainerGroup",
        "type": "Microsoft.ContainerInstance/containerGroups",
        "apiVersion": "2017-08-01-preview",
        "location": "[resourceGroup().location]",
        "properties": {
            "containers": [
                {
                    "name": "myContainer",
                    "properties": {
                        "image": "seanmckenna/aci-helloworld-multiport",
                        "ports": [
                            {
                                "port": "80" 
                            },
                            {
                                "port": "443"
                            }
                        ],
                        "resources": {
                            "requests": {
                                "cpu": "1.0",
                                "memoryInGb": "1.5"
                            }
                        }
                    }
                }
            ],
            "osType": "Linux",
            "ipAddress": {
                "type": "Public",
                "ports": [
                    {
                        "protocol": "tcp",
                        "port": "80"
                    },
                    {
                        "protocol": "tcp",
                        "port": "443"
                    }
                ]
             }
        }
    }
]

You can deploy the template using az group deployment create (full documentation):

az group deployment create -n myDeployment --template-file azuredeploy.json --parameters @azuredeploy.parameters.json -g myResourceGroup

Answer 4

Since ports ( indicated by [] ) property is an array you can add more elements to it:

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {

        "type": "string",
        "defaultValue": "acilinuxpublicipcontainergroup"
    },    
    "image": {

                                }

                                    "memoryInGb": "[parameters('memoryInGb')]"
                                }
                            }
                        }
                    }

                            "protocol": "tcp",
                            "port": "[parameters('port')]"
                        },
                        {
                            "protocol": "tcp",
                            "port": "[parameters('port2')]"
                        }
                    ]
