GITSIGN IN REMOTE ENVIRONMENTS

After attending SigstoreCon, I got inspired by Priya Wadhwa’s Keynote: Signing Git Commits with Gitsign, to finally set up gitsign for my dev environment. It seemed straightforward enough, right?

BRINGING FIRST-CLASS SUPPORT TO SBOMS AND ATTESTATIONS FOR CONSTELLATION CONTAINERS

In a previous post, we explored how to generate a Software Bill of Materials (SBOM) and subsequently scan them for vulnerabilities. In this post, we show you how SBOMs can be signed and then stored in the same container registry as the scanned image. This improves security & discoverability!

MY FAVORITE TOOLS TO KEEP A ZERO VULNERABILITIES POSTURE FOR CONSTELLATION

In our last post, we explored how Software Bill of Materials (SBOMs) provide us with a transparent view of all dependencies in Constellation. In this post, we explore how we can use this information to continuously monitor vulnerabilities and upgrade to patched versions as soon as they are available.

GENERATING SBOMS FOR CONFIDENTIAL KUBERNETES IS EASIER THAN YOU THINK!

Constellation is an infrastructure product and includes several different components:

VERIFY COSIGN SIGNATURES IN GO USING SIGSTORE/SIGSTORE

After integrating cosign into the release process of Constellation’s CLI, I also wanted to improve the supply chain security of our metadata that are used for attestation.

WHAT CAN CONFIDENTIAL COMPUTING DO FOR THE KUBERNETES COMMUNITY?

This is a summary of the talk I gave at the Kubernetes Community Days (KCD) Berlin 2022. Both, the slides and a recording are available.

POSTMORTEM: UNRAID FLASH DEVICE FAILURE

Status: Complete, action items in progress.

Summary: unRAID’s OS Flash Device failed undetected for 14 days, preventing server to successfully reboot, taking all internal services down, including pfSense VM which prevented home network from accessing internet.

CONFIGURE DNS:NET AS ISP ON PFSENSE ROUTER

Since DNS:NET provides support only for a limited number of supported routers, and pfSense is not on that list, I will share my configuration here.

CONTROL VIRTUALBOX VMS VIA BATCH

VirtualBox GUI is slow for repetitive tasks such as starting & stopping virtual machines. In addition, some tasks such as starting VMs headless is not possible at all.

TRAEFIK 2 AS DOCKER REVERSE PROXY ON UNRAID

Hosting multiple containers on unRAID, and keeping track of their port mappings can become quite annoying. Using a reverse proxy as a single point of entry will allow us to hide this from the user, and use easy to remember DNS records instead.
