packer-vsphere

Previously known as jetbrains-infra/packer-builder-vsphere, it is now the official vSphere integration for Packer: https://github.com/vmware/packer-plugin-vsphere.

I added the following features:

Upload an ISO to a datastore before building a vSphere template, https://github.com/jetbrains-infra/packer-builder-vsphere/pull/164
Add a force option to deregister an already existing template with the same name, https://github.com/jetbrains-infra/packer-builder-vsphere/pull/186
Fill the “note” field of a template to save some information, https://github.com/jetbrains-infra/packer-builder-vsphere/pull/185

terraform-provider-ovh

I implemented the first version of the ovh_domain_zone_record resource for the OVH Terraform provider.

Hi, I’m Rémi. I live in the suburd of Paris at Saint-Ouen-sur-Seine. I started as a system administrator (SRE/DevOps call it whatever you want) and evolved as a System Architect; I design architectures at scale for distributed systems. I’m currently working at Outscale on the IaaS orchestrator team.

I make occasional open-source contributions and love to deep-dive into technical subjects.

I also love home automation, rap music, video games that tell stories, traveling, and biking at night in Paris.

AF_VSOCK

VSOCK is not new anymore it has been around in Linux kernel since 4.8. For those who do not know what this is, it was previously developed by VMware under the name VMCI. AF_VSOCK is a socket address family like AF_INET or AF_UNIX. It’s an address family designed for communication between a VM (guest) and the underlying hypervisor (host), you can also build communication between multiple guests on the same host. Previously, this kind of communication was done with a serial port, a great example is https://pve.proxmox.com/wiki/Qemu-guest-agent.
