[Feature]: Thin provisioning disks

[EHRETic]

Is your proposal related to a problem?

The only problem is backup size because of big Docker volumes 😊 (probably, this feature would be nice on Windows & mac)

Describe the solution you'd like.

The ability to choose between thin provisioning disks and fat ones at VM creation

Describe alternatives you've considered.

Don't know if there is any alternative to consider, either it is feasible, or it is not! 😉

Worth a try, thanks in advance

Additional context

An example : 10 GB used but on server's disk, it is taking 256GB :

You can do this already:

environment:
  DISK_FMT: "qcow2"

[EHRETic]

You can do this already:

environment:
  DISK_TYPE: "qcow2"

Did I miss this? If yes, very sorry!

[kroese]

No problem, its not written in the FAQ.

[EHRETic]

Will be valid for others then, thanks a lot! 😉👌

[EHRETic]

Extra question, is it valid for several disks?

 environment:
   DISK_TYPE: "qcow2"
   DISK2_TYPE: "qcow2"`

etc...

[kroese]

No.. you can specify only a single type for all disks currently

[EHRETic]

No.. you can specify only a single type for all disks currently

That is fine for me 👌

Mmmhhh, came into this issue (looping error):

Any clue, is there any typo?

[kroese]

Yes, sorry I made a typo.

Its not DISK_TYPE but DISK_FMT:

environment:
  DISK_FMT: "qcow2"

[EHRETic]

Yes, sorry I made a typo.

Its not DISK_TYPE but DISK_FMT:

Marvelous, that works, thanks a lot! 👌
