Compute

You can configure compute resources for your service like this:

  • dashboard

  • toml

compute slider

If you are configuring the resources via the configuration file instead of using the dashboard, keep in mind that cpu and memory allocation need to follow the following rules:

  • The value of the memory parameter must be exactly 2,048 times the value of the cpu parameter.
  • The value of the memory parameter must be within the range of 128 to 7,168 (inclusive).

Don’t forget you can use nhost run config-validate command to verify your values are correct.

Storage

By default a container’s disk is ephemeral so data isn’t persisted across reboots. If your service needs persistent storage you can attach one or more SSD disks by adding the following configuration:

  • dashboard

  • toml

storage

With the above configuration, two disks will be provided. The first disk named database will have a capacity of 10 GiB and will be mounted at /var/lib/db. The second disk named data will have a capacity of 1 GiB and will be mounted at “/mnt/data.

Please note that renaming a disk will result in the destruction of the old disk and the creation of a new one, potentially leading to data loss.
Volume capacity can not be decreased. Once a volume with a given size has been created, its capacity can only by expanded.

It’s important to note that disks are unique to each service and cannot be shared across multiple services.

Pausing a service

To pause a service, simply set its number of replicas to 0:

  • dashboard

  • toml

pausing a service

When you pause a service, it will cease running while keeping any associated disk and registry intact.

While the service is paused, computing costs will not be charged. However, storage costs will continue to apply.
