Secure. Reliable. Economical. All three. We have embraced failures to create a reliable municipal hybrid cloud with unreliable components, economically.
Kustomizing Kustomize: Releasing Our Tools
Declarative. It becomes a way of life. We have chosen kustomize to safely build our inventory of YAML, including Istio and Cert-Manager. But, it has proven incredibly non-DRY. After some refactoring etc, I made a few Generators and Transformers to cover some… Read More »Kustomizing Kustomize: Releasing Our Tools
Declarative GitFlow: restrict kustomize to master branch
Prevent accidents from happening on un-merged feature branches with GitFlow and kustomize.

The dangers that lurk inside your Kubernetes Cluster, what to watch out for.
Cloud Security Blasphemy: Secrets in git
Ever wondered why so many breaches happen due to secrets being checked in to source control?
Want to make it easy to commit them to git, and be secure at the same time?
Read On!
Keep your certificates young and fresh
TLS certificates, unlike wine, do not get better with age. Refresh them before they hit the end of their lifecycle.
That’s the kind of password an idiot uses on luggage: cloud security
Passwords. bits of plain text that end up everywhere in automated systems. etcd. A `secure` way to share secrets. The Internet. A place that everything is guaranteed to end up. This is a toxic brew, read on!
The naked cloud: elasticsearch is stretch but doesn’t cover security
Wide open elasticsearch on the Internet. Its common. The user usually believes since they use private IP (NAT) they are protected. Wrong.
Static Application Security for Nodejs (with Gitlab CI)
Static application security for nodejs and Gitlab CI without changing your containers. SAST the easy way using docker FROM.
Safely secure secrets: a sops plugin for kustomize
Secrets get committed to git, forgotten, and then resurrected by the wrong people later.
Don’t let this happen to you, use sops.
And be declarative, use kustomize.
And do it with this cool new library I wrote.
They got in via the logging! remote exploits and DDoS using the security logs
Amplification attacks occur when a small request causes a larger response. NTP and DNS have both been prone to this, but now cloud logging? Read on!
Increasing the usefulness of your Kubernetes Ingress logging
Using fluent-bit annotations can increase the usefulness of your Kubernetes nginx-ingress logging. Create a custom regex parser.
When your security tools cost more than the thing they protect

What a wicked NAT we weave: detangling the cloud
Cloud. It achieves its elastic nature using Load Balancers and Proxies. The sad side affect of these is they remove the source IP. Let’s try to bring it back.
