I have hit a limit of 10Gb for default root volume size. For this particular container I need a larger size.
So far I've seen quite dirty hacks to override default size.
Could somebody provide me and the community with a clear example of specifying bigger volume size upon container creation? Thanks!
I'm going to offer an alternative suggestion - don't. Stop and ask yourself why you need a larger root volume. I would suggest it's likely to be because you're doing something that can be done a better way.
I would suggest that instead - you use a storage container (if another 10G would be sufficient) or use a passthrough mount to a local disk.
The problem with big containers is they're somewhat at odds with what containerisation is trying to accomplish - compact, lightweight and self contained program instances.
So I would suggest instead:
docker create -v /path/to/storage:/container_mount --name storage_for_my_app /bin/true
(Or you can just -v /container_mount to keep the data within the container)
Then when you fire up your container:
docker run -d --volumes-from storage_for_my_app your_image
However it may be useful to note - as of Docker 1.9, the size limit is 100G instead: https://docs.docker.com/engine/reference/commandline/daemon/
