Animated architecture diagram for Kubernetes showing how Vault Agent Injector injects Vault Agent sidecars through an Admission Controller. The sidecars automate the process of authenticating to Vault and rendering secrets to shared memory volumes.

#Vault Agent Injector is a powerful tool for #Kubernetes and #OpenShift that removes the need for native secrets and complex RBAC by injecting secrets directly into pods at runtime. The Vault Agent sidecar automates authentication and rendering of secrets to shared volumes!

Had a great time presenting at the San Antonio #HashiCorp User Group (HUG). It was fun and exciting to get the group meeting again after 5 years!

If you're in the area and want to meet with local practitioners, or even want to present on a topic, be sure to join the next event!

Experimenting with `uv` recently, a blazing-fast #Python package manager, and it's making #distroless images easier to work with. Hyper-fixated on image size optimizations 🫠

For my use case, size breakdown:
🐍 python (base): 1.07 GB
🐍 python (slim): 192 MB
🐍 distroless (w/ uv): 101 MB

All technical skill levels and backgrounds welcome. Submit by December 1, 2024!

This global edition of HashiTalks follows the sun ☀️ as we hear from practitioners around the world share their #HashiCorp story for 24-consecutive hours.

That little countdown on 2FA apps stresses the shit out of me. I feel like I'm diffusing a bomb.

If it gets into the red, I just wait. I can't handle the stress.

Recently, I've had the need for a multi-cluster Vault setup (Performance/DR Replication). I built a repo to quickly spin up a multi-cluster Vault environment locally using docker. (TF coming soon).

Useful for debugging replication issues, or even practicing DR failovers!
