Tmpfs support

[stefano]

Hello,

tmpfs is a way to have an in-memory filesystem available to the container, so that the application can work on temporary files very fast.

In our case, we need this to work on temporary SQLite database, that need to be serialized as files, but are volatile thus don’t need a fully fledged filesystem, nor can afford its low performance.

tmpfs is supported by docker and AWS ECS:

• https://docs.docker.com/engine/reference/run/ (section TMPFS)
• https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html (section tmpfs)

It would be very nice to have a section in convox.yml that would allow the definition of a tmpfs for a given service. Something like this:

tmpfs:
  containerPath: /some/path
  size: 1000
  mountOptions:
    - ro
    - noatime

Would this be very complicated to implement?

Thanks
Kind regards

today we faced simillar issue, 3rd party container which is using it, so we got forced to deploy it on ec2

maybe its worth re-considering ?

Good morning @here,

We have an item for this on our backlog. I will discuss it with the team during our next planning meeting to see if I can get any idea as to the priority or timeline.

Regards,
Nick
