The
Deployment-Gate Checklist: Turning Sign-off Into a Control

Category: Deployment Governance / Reusable Client
Template

A one-page control, not a suggestion list. Every checkbox below
should be treated as a gate: a deployment isn’t “done” until its
applicable rows are checked, and a checkbox that can’t be checked is
itself the finding to raise - before shipping, not after.

This checklist grew out of a real, recurring pattern across more than
a dozen separately operated system instances: the same handful of
process gaps kept causing production incidents, not because anyone
lacked the skill to fix them, but because there was no standing control
forcing the check to happen every single time. Below is the generalized,
platform-agnostic version.

1. Deployment Process

• All boot-time/startup configuration
  is scripted and version-controlled - no required value depends on a
  person remembering a manual step
• A mandatory post-deploy smoke test
  runs before sign-off (confirm the application responds successfully, and
  check fresh logs for new errors in the last several
  minutes)
• Deployment is a full service
  restart, not a hot-redeploy - and the previous process is confirmed
  fully stopped before the next one starts
• The deployment procedure is an
  executable checklist or script, not a narrative document - a description
  of steps has no way to enforce that a step actually
  happened

2. Data / Environment Readiness

• Schema or structural migrations are
  synchronized with the application deployment as one atomic step, not
  applied separately per environment
• The data tier is verified up and
  accepting connections before the application tier starts, as an
  explicit pre-flight check
• Credential rotations and the
  corresponding config updates happen in the same change window, with a
  connection test confirming success

3. Build / Packaging

• The deployed artifact and its
  dependency set are standardized per environment, with a pre-ship
  checklist confirming required libraries are present
• Hand-edited configuration files are
  validated (linted) before restart - a single malformed value should
  never reach a live parser untested

4. Security

• Any network-exposed service
  component is confirmed reachable only from where it’s intended to be
  reachable
• No plaintext credentials remain in
  configuration files that might be copied, zipped, or shared - use a
  secrets manager or encrypted credential store

5. Documentation & Naming

• File and bundle names don’t reuse a
  pattern (e.g., “logs”) for content that isn’t actually that - naming
  collisions cause someone to grab the wrong file during a future
  incident
• A manifest (name, size, hash)
  travels with any evidence or file bundle shared externally

6. Standing Workstreams

• Any defect too large to fix in a
  single ticket is tracked as its own ongoing workstream, with a named
  owner, rather than being closed and reopened repeatedly as isolated
  incidents

How to use this checklist: Copy it into your own
deployment runbook and treat every applicable row as a required gate,
not a best-effort suggestion. A row that can’t honestly be checked off
is not a reason to skip it - it’s the single most valuable finding in
the whole deployment, because it tells you exactly where the next
incident is going to come from.
