Topographic paper terrain with container-shaped markers following a measured route to a bounded plateau

Preflight survey / Docker + Podman

Find the edge before your fleet does.

Measure startup p95, published-port pressure, mounts, and headroom on the host you actually plan to use—then validate the prediction with a second controlled run.

Field evidence / 01

A capacity claim you can reproduce.

The probe turns a sandbox shape into host-specific evidence instead of a generic container limit. Every result names the runtime, context, image, load shape, and caveats.

COORD / A

Observe the slope

Start containers at quartile levels, measuring time-to-running while published bindings and mounts accumulate.

COORD / B

Mark the contour

Fit a conservative p95 trend and compare it with your startup budget: comfortable, watch, or exceeded.

COORD / C

Walk it again

Repeat the same shape later. scp compare reports prediction error and whether it meets the 25% target.

Runbook / 02

Explicit, isolated, cleaned up.

  1. Name and confirm the target.Production-like names are refused unless separately overridden.
  2. Review a dry run.See the maximum starts, ports, mounts, and measurement levels without runtime access.
  3. Measure and compare.Save JSON, repeat under controlled load, and quantify prediction accuracy.

Route sketch / 03

Map the shape. Measure the host.

This local planner is a transparent planning estimate, not a benchmark. Use the generated command to replace it with evidence from your runtime.

Operator pack / 04

Keep several routes on the same map.

Planner Pro saves and compares up to five local scenarios. The complete CLI, safety behavior, JSON reports, and CSV export remain free.
