Using #sigstore #gitsign and #cosign with #wsl

Sigstore has been all over my newsfeeds for their efforts in supply chain security especially signing containers and SBoMs documents with shortlived key pairs using cosign. This “keyless” approach can also be applied to signing git commits using gitsign eliminating the need for PGP key pairs. Utilizing these tools involves authenticating via OIDC in a browser. In WSL this requires some preparation to open the authentication page in the default browser on Windows.

#Renovate all the things - Automate dependency updates for container images #Docker

Modern software is built on top of dozens if not hundreds of dependencies. This help developers to focus on business value instead of reinventing the wheel. But those dependencies must be updated to prevent shipping security vulnerabilities. Renovate scans your source code repository for a wide range of languages and offers updates as merge requests. This post provides an introduction to use Renovate with Docker, containers and container images.
