Max memory per Container Instance in an ACR

Question

Hey,

I see that the max memory for a Container Registry ist 16gb. Is this shared across Containers or summed?

Let's say I have 4 containers that are build sequentially with a github actions script.

Do I have to split my memory across the 4 containers i.e. 4 each or can I use 16 everywhere?

Hi RSale,
Thank you for reaching out to the Microsoft Q&A platform.

Based on your question, we understand that you want to know about the Max memory per Container Instance in an ACR.

The max memory per Container Instance in an ACR is indeed 16GB this limit applies to a container group, not individually to each container. This means that the memory is summed across containers in a group.

If you have 4 containers you can use up to 16GB of memory in total, but you don't have to split it equally across the 4 containers. You can allocate the memory as needed, as long as the total memory usage does not exceed 16GB.

Example, you could have one container using 8GB of memory, another using 4GB, and the remaining two using 2GB each, as long as the total memory usage is 16GB.
