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 resources, as well as the availability of the service in Azure regions.

Service quotas and limits

Number of containers per container group 60
Number of volumes per container group 20
Ports per IP 5
Container instance log size - running instance 4 MB
Container instance log size - stopped instance 16 KB or 1000 lines
Container creates per hour 3001
Container creates per 5 minutes 1001
Container deletes per hour 3001
Container deletes per 5 minutes 1001

Feature availability

Azure Container Instances can schedule both Windows and Linux containers with the same API. However, the following features are currently available only in Linux container groups. Windows support is planned.

  • Multiple containers per container group
  • Volume mounting (Azure Files, emptyDir, GitRepo, secret)
  • Virtual network (preview)
  • GPU resources (preview)

Region availability

Azure Container Instances is available in the following regions with the specified CPU and memory limits for each container group. Values are current at time of publication. For up-to-date information, use the List Capabilities API.

Availability and resource limits may differ when using Azure Container Instances with a virtual network (preview) or with GPU resources (preview).

Location OS CPU Memory (GB)
Canada Central, Central US, East US 2, South Central US Linux 4 16
East US, North Europe, West Europe, West US, West US 2 Linux 4 14
Japan East Linux 2 8
Australia East, Southeast Asia Linux 2 7
Central India, East Asia, North Central US, South India Linux 2 3.5
East US, West Europe, West US Windows 4 14
Australia East, Canada Central, Central India, Central US, East Asia, East US 2, Japan East, North Central US, North Europe, South Central US, South India, 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).
