A show about getting your best ideas into the world and seeing what happens. We talk about code, ops, infrastructure, and the people that make it happen. Gerhard Lazu and friends explore all things DevOps, infra, and running apps in production. Whether you’re cloud native, Kubernetes curious, a pro SRE, or just operating a VPS… you’ll love coming along for the ride. Ship It honors the makers, the shippers, and the visionaries that see it through. Some people search for ShipIt or ShipItFM and can’t find the show, so now the strings ShipIt and ShipItFM are in our description too.
Container base images with glibc & musl
In today’s episode, we talk about distroless, ko, apko, melange, musl and glibc. The context is Wolfi OS, a community Linux OS designed for the container and cloud-native era. If you are looking for the lightest possible container base image with 0 CVEs and both glibc and musl support, Wolfi OS & the related chainguard-images are worth checking out.
Ariadne Conill is an Alpine Linux TSC member & Software Engineer at Chainguard.
