Azure Container Instances disk space pricing

Question

This doesn't seem to be listed neither on the Microsoft portals, or be answered anywhere else - so I might have misunderstood how this is provisioned and/or calculated in Azure, but;

Instancing a container instance in Azure, with an image from my Azure Container Registry, how is disk space billed? I understand the whole memory/CPU billed-by-the-second, but what about the disk space taken up by the running instance?

The official docs seems to be very vague about this.

Answer 1

When an Azure Container Instance is launched it has an amount of disk space available to the container. You have no control over this and are not explicitly charged for it.

Having just ran this command

az container create --image node:8.9.3-alpine -g "Test1" \
  -n test1 --command-line 'df -h'

The response shows...

Filesystem                Size      Used Available Use% Mounted on

tmpfs                   958.9M         0    958.9M   0% /proc/kcore
tmpfs                   958.9M         0    958.9M   0% /proc/timer_list
tmpfs                   958.9M         0    958.9M   0% /proc/timer_stats
tmpfs                   958.9M         0    958.9M   0% /proc/sched_debug

So you should have 48gb of disk space to play with.

(I tried to test this with a Win Image, but got hit by a bug trying to get the information out)
