Ingress-NGINX Retired in March 2026 — Here's Exactly What Ingress2Gateway Migrates, and What It Doesn't
Ingress-NGINX officially retired in March 2026. Here's the annotation-by-annotation breakdown of what Ingress2Gateway migrates cleanly to Gateway API, what it can't touch, and why the gaps are riskier for a multi-tenant fleet than a single app.
The Mexico Breach Wasn't a Jailbreak. It Was a File Claude Reloaded on Every Run
A single attacker jailbroke Claude Code once, then breached nine Mexican government agencies across 34 sessions without ever repeating the jailbreak — because Claude wrote its own jailbroken instructions into a file it auto-loads every run. Here's the exact mechanism, and what it means for any agent-operated deploy pipeline that trusts persisted state.
Redis Got Patched Twice in 79 Days: The Real AI Discovery Story vs. the One Trending on X
Redis patched five RCE vulnerabilities in May 2026, then had to patch the same bug classes again in July after PoCs beat the 'fixed' builds. Here's the verified timeline, what the viral Kimi K3 AI-discovery claim actually is (and isn't), and what a 79-day incomplete-fix window means for a platform's own patch cadence.
Ingress-NGINX Is Already Retired: An Ingress2Gateway Migration Walkthrough for Self-Hosted Clusters
Ingress-NGINX's retirement isn't a future deadline — it happened in March 2026, and unpatched clusters have been exposed for months since. A concrete ingress2gateway walkthrough against a real annotation set shows exactly what converts automatically and what needs a hand pass.
Kubernetes 1.35 Makes Supplemental Groups Strict: Closing the Shared-Volume Leak Hiding in Every Tenant Image's /etc/group
Kubernetes 1.35 lets a Pod ignore the supplemental groups baked into a container image's /etc/group — closing a quiet leak where an untrusted tenant image could silently gain access to another tenant's shared volume.
Kubernetes 1.36's PSI Metrics Graduate to GA: What Pressure Stall Information Catches About Resource Starvation That CPU% Utilization Misses
Kubernetes 1.36 locks PSI metrics to GA, catching resource stalls a CPU% dashboard can't see. Here's the worked example, the two ways the signal can lie, and the pre-flight checklist a bare-metal fleet needs before trusting it.
The Rollback Floor: Designing a Deploy-From-Chat MCP Server That Can't Roll Back Too Far
A dashboard's rollback button only ever offers 'go back one.' An MCP tool wrapping the same API can't assume that restraint — here's a concrete tool contract, server-side floor, and audit schema that stop an agent from rolling back past the last known-good release.
Wassette Runs MCP Tools as WebAssembly, Not Containers: What That Actually Buys a Self-Hosted Fleet
Microsoft's Wassette runs MCP tools as WebAssembly Components with deny-by-default WASI permissions instead of a container or a Firecracker microVM. Here's what the microsecond instantiation and policy.yaml grants actually buy a self-hosted fleet — and the GPU access, fork(), and resource-quota gaps that still mean a heavier sandbox for everything else.
Your MCP Server Doesn't Know Who's Deploying. WorkOS's OAuth 2.1 Stack Fixes That
Most MCP servers still trust a bearer token in an env var. WorkOS's May 2026 OAuth 2.1 stack — CIMD, Resource Indicators, and on-behalf-of token exchange — finally answers the question a deploy-authority MCP server can't skip: which agent, acting for whom, just asked to ship to production?
