All Azure services include certain default limits and quotas for resources and features. This article details the default quotas and limits for Azure Container Instances.

Availability of compute, memory, and storage resources for Azure Container Instances varies by region and operating system. Use the List Usage API to review current quota usage in a region for a subscription.

To request a limit increase, create an Azure Support request. Free subscriptions including Azure Free Account and Azure for Students aren't eligible for limit or quota increases. If you have a free subscription, you can upgrade to a Pay-As-You-Go subscription. 2Default limit for Pay-As-You-Go subscription. Limit may differ for other category types.

For more detailed overview regarding limitations, you can go through below link

if there are any further questions regarding the documentation, please tag me in your reply and we will be happy to continue the conversation.

@AjayBathini-MSFT Thank you for providing the information. However, this cannot answer my question. I would like to confirm the default value of ports per IP address. In the ACI document, the limit is 5, but it shows the limit as 10 in the CLI. They are not matching. Could you please check which one is the default value?

@AjayBathini-MSFT ACI support team does not have the information of the default value of the port limit. Is it possible to engage the ACI product managers to have the answer?

[AjayBathini-MSFT]

@RolandlinAKS I'm going to assign this to the document author so they can take a look at it accordingly.

[AjayBathini-MSFT]

@tomvcassidy Could you please add your inputs on the above query.

[RolandlinAKS]

Apart from above query, the customer also have a question that if one container group can use both TCP and UDP ports?

[RolandlinAKS]

@tomvcassidy Could you please review this issue?

1. What is the exact port limit for each IP address? It shows 5 in the ACI document, while it shows 10 in the Azure CLI output.
2. Does one container group can use both TCP and UDP simultaneously if they are not the same port?

The customer is waiting for the response.

[RolandlinAKS]

Do we have any update on this?

[RolandlinAKS]

@AjayBathini-MSFT I have got the confirmation from Microsoft internal channel that ACI has a hard limit of 5 ports per IP. The CLI output is not correct and the product team will fix the printed output in CLI. We can close this case.
