In ECE template configuration page, we can create dedicated master type instance.
For sizing part, we can set memory-to-disk ratio.
If we set a high ratio like 32, ece will allocate 32GB disk per 1GB memory.
So if user choose 4GB for dedicated master , ece will allocate 128GB disk for this instance.
As we know, master node mainly uses memory and doesn't require high disk size. 20GB should be enough for one master node no matter how much its memory size is. 128GB is too much and may be a waste.
So my question is how can we limit master type instance to specified disk size like 20GB.
