Part of https://github.com/neondatabase/cloud/issues/13127. Resolves #9153 What changed in this PR: 1. Adds `ComputeSpec.disk_quota_bytes: Option<u64>` 2. Adds new arg to compute_ctl: `--set-disk-quota-for-fs <mountpoint>` 3. Implements running `/neonvm/bin/set-disk-quota` with the right value if both cmdline arg AND field in the spec are specified 4. Patches `/etc/sudoers.d` to allow `compute_ctl` to set quota with sudo This PR is very similar to the swap support added earlier, you can take a look at it as prior art: #7434 In theory, it can be implemented outside of compute_ctl when we will have a separate neonvm daemon, but we are not there yet. Current implementation is the simplest possible to unblock computes with larger disks. All code related to usage of `/neonvm/bin/set-disk-quota` is located in `disk_quota.rs`. We need to call this script with the following arguments: `/neonvm/bin/set-disk-quota {size_kb} {mountpoint}`. Quotas are set on the filesystem level, so we need to provide path to the directory that filesystem was mounted to. I tested this change locally with https://github.com/neondatabase/cloud/pull/17270. It should be safe to merge, because this feature is gated by both cmdline arg and field in the spec. If control-plane doesn't set values in both places, compute_ctl won't be affected by this change.
Control Plane and Neon Local
This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command.
Example: Start with Postgres 16
To create and start a local development environment with Postgres 16, you will need to provide --pg-version flag to 3 of the start-up commands.
cargo neon init --pg-version 16
cargo neon start
cargo neon tenant create --set-default --pg-version 16
cargo neon endpoint create main --pg-version 16
cargo neon endpoint start main
Example: Create Test User and Database
By default, cargo neon starts an endpoint with cloud_admin and postgres database. If you want to have a role and a database similar to what we have on the cloud service, you can do it with the following commands when starting an endpoint.
cargo neon endpoint create main --pg-version 16 --update-catalog true
cargo neon endpoint start main --create-test-user true
The first command creates neon_superuser and necessary roles. The second command creates test user and neondb database. You will see a connection string that connects you to the test user after running the second command.
