I plan to use this when launching a fast_import job in a VM. There's currently no good way for an executable running in a NeonVM to exit gracefully and have the VM shut down. The inittab we use always respawns the payload command. The idea is that the control plane can use "fast_import ... && poweroff" as the command, so that when fast_import completes successfully, the VM is terminated, and the k8s Pod and VirtualMachine object are marked as completed successfully. I'm working on bigger changes to how we launch VMs, and will try to come up with a nicer system for that, but in the meanwhile, this quick hack allows us to proceed with using VMs for one-off jobs like fast_import.
This directory contains files that are needed to build the compute images, or included in the compute images.
compute-node.Dockerfile To build the compute image
vm-image-spec.yaml Instructions for vm-builder, to turn the compute-node image into corresponding vm-compute-node image.
etc/ Configuration files included in /etc in the compute image
patches/ Some extensions need to be patched to work with Neon. This directory contains such patches. They are applied to the extension sources in compute-node.Dockerfile
In addition to these, postgres itself, the neon postgres extension, and compute_ctl are built and copied into the compute image by compute-node.Dockerfile.
