β‘οΈ LocalStack archived its GitHub repo β what happened and what it means
On March 23, 2026, LocalStack archived localstack/localstack on GitHub (read-only) and consolidated everything into a single Docker image that requires an auth token β including in CI.
What changed:
- docker pull localstack/localstack:latest without LOCALSTACK_AUTH_TOKEN β your pipeline breaks
- Free "Hobby" plan exists but requires account creation and is non-commercial only
- Paid plans start at $39/mo
- CI needs a dedicated CI Auth Token stored in secrets
Your options:
- Pin to an older tag (e.g. 4.12) β works short-term, but you accumulate parity drift and unpatched CVEs
- Create a free account β enough for individual non-commercial dev
- Pay β if LocalStack is embedded in team CI
For open-source projects: LocalStack launched a separate program offering free Ultimate tier licenses (100+ AWS services, Cloud Pods, IAM enforcement) to eligible OSS projects with OSI-approved licenses.

Trivy has been hacked, again.
The malicious payload is designed to execute within GitHub Actions runners, targeting sensitive data in CI/CD environments. Observed behavior includes dumping runner process memory to extract secrets, harvesting SSH keys, and exfiltrating credentials for AWS, GCP, and Azure, as well as Kubernetes service account tokens.

As announced November 2025, Kubernetes will retire Ingress-NGINX in March 2026. Despite its widespread usage, Ingress-NGINX is full of surprising defaults and side effects that are probably present in your cluster today. This blog highlights these behaviors so that you can migrate away safely and make a conscious decision about which behaviors to keep. This post also compares Ingress-NGINX with Gateway API and shows you how to preserve Ingress-NGINX behavior in Gateway API. The recurring risk pattern in every section is the same: a seemingly correct translation can still cause outages if it does not consider Ingress-NGINX's quirks.
