deploying-azure-container-appslisted

Deploys Docker containers to Azure Container Apps with scale-to-zero that actually scales to zero — cooldownPeriod kept at 300s, KEDA cron warm windows instead of minReplicas 1, Jobs for anything async, and the retirement checklist that stops CI resurrecting a deleted app. Covers multi-container sidecars, shared managed environments, Container Apps Jobs, the az rest PATCH escape hatch for CLI flags that silently no-op, and the job-start env-override trap. Use when SWA + FC1 don't fit — long-running servers, WebSocket/SSE, Next.js with middleware, custom runtimes, scheduled or queue-driven background jobs.

# Deploying Azure Container Apps Scale-to-zero Docker containers for workloads SWA + FC1 can't handle: long-running servers, WebSocket/SSE, streaming, custom runtimes, multi-process sidecars, and run-to-completion background jobs. ## When to use Container Apps | Need | Use | |------|-----| | CRUD API + React frontend | SWA — not this | | Timer/queue trigger, AI workload, < 30 min | FC1 — not this | | Long-running HTTP server, > 30s requests | **Container App** (this skill) | | WebSocket / SSE / streaming | **Container App** with `--request-timeout 1800` | | Sidecar (e.g. headless browser, embedded DB) | **Container App** multi-container | | Batch / cron / one-shot processor | **Container Apps Job** (this skill, jobs section) | | Multiple related apps sharing logs/networking | **Shared managed environment** (this skill) | ## Cost defaults | State | Cost | |-------|------| | Idle (`minReplicas: 0`, `cooldownPeriod: 300`) | $0 | | Active (template default 0.5 vCPU / 1 GiB) | pennies/month at low traffic | | Always warm (`minReplicas: 1`, or `cooldownPeriod` longer than your traffic gaps) | ~A$8/day for a 1.5 vCPU replica, ~US$5/mo for the smallest | | Log Analytics workspace | bound by `dailyQuotaGb` on the workspace (see [instrumenting-azure-app-insights](../instrumenting-azure-app-insights/SKILL.md)) | **Scale-to-zero is a whole-system property, not a config value.** Four things silently pin a `minReplicas: 0` app at one billed replica 24/7 (gotchas #41–#45): something c
