Quotas and region availability for Azure Container Instances

All Azure services include certain default limits and quotas for resources and features. The following sections detail the default resource limits for several Azure Container Instances (ACI) resources, as well as the availability of the ACI service in Azure regions.

Service quotas and limits

Resource Default Limit
Container groups per subscription 1001
Number of containers per container group 60
Number of volumes per container group 20
Ports per IP 5
Container creates per hour 3001
Container creates per 5 minutes 1001
Container deletes per hour 3001
Container deletes per 5 minutes 1001
Multiple containers per container group Linux only2
Azure Files volumes Linux only2

2 Windows support for this feature is planned.

Region availability

Azure Container Instances is available in the following regions with the specified CPU and memory limits.

Location OS CPU Memory (GB)
East US, North Europe, West Europe, West US, West US 2 Linux 4 14
Japan East Linux 2 8
Australia East, East US 2, Southeast Asia Linux 2 7
Canada Central, Central India, East Asia, North Central US, South Central US Linux 2 3.5
East US, West Europe, West US Windows 4 14
Australia East, Canada Central, Central India, East Asia, East US 2, Japan East, North Central US, North Europe, South Central US, Southeast Asia, West US 2 Windows 2 3.5

Container instances created within these resource limits are subject to availability within the deployment region. When a region is under heavy load, you may experience a failure when deploying instances. To mitigate such a deployment failure, try deploying instances with lower CPU and memory settings, or try your deployment at a later time.

Let the team know of additional regions required or increased CPU/Memory limits at aka.ms/aci/feedback.

Next steps

Certain default limits and quotas can be increased. To request an increase of one or more resources that support such an increase, please submit an Azure support request (select "Quota" for Issue type).
