Pattern

CI Cache Invalidation Loop

ci-cache-invalidation-loop

A recurring CI shape where ephemeral runners and poorly-scoped Docker/GitHub caches force rebuilds and repeated pulls, so build/deploy time stays high until caching is preserved, permissioned, and restored at the right workflow steps.

Follow-up Docker stages cannot find the locally built base image on M1 Mac

In a Next.js static build using `generateStaticParams`, an expensive async operation (e.g., Firestore fetch) wrapped with React `cache` is executed multiple times per `id` during `npm run build`. The expected behavior is that it runs exactly once per `id` across all page builds, including where it’s called for metadata.

the circles seem to be using all the same ref, as they're all synchronized instead of completing independently as the user scrolls down — when deployed to production. Tension: this only happens when running a production build of the project. Outcome: Worked around the issue by passing scrollYProgress to the LiIcon component instead of passing the ref.

the cache doesn't work across processes — workers might be pre-forked. Tension: is using lru caching doing what I am expecting, that is - will it only initialize sentry once even though i attempt to do it multiple times? Outcome: provided it's called within the same process.

re-runs every migration via a raw `for f in migrations/*.sql; psql -f` loop — A CI deploy workflow. Tension: it relies on tolerated `relation X already exists` errors to make non-idempotent legac.

This is triggered when I push the branch `mjd/try-claude-in-ci-20251216`. — on: push: branches: [ '**/ci-*' ]. Tension: I don't understand why, since it ought to match only a branch name containing `/ci-`. Outcome: A bug? Or have I misunderstood something?

fatal: detected dubious ownership in repository at '/github/workspace/docs/build/html' — Run ad-m/github-push-action@v0.5.0. Tension: To add an exception for this directory, call: git config --global --add safe.directory /github/workspace/docs/build/html. Outcome: The problem was that the workflow declared the safe directory outside of the docker containter.

the macos job keeps on hanging — I'm trying to set up a CI/CD pipeline for a flutter desktop app on Github Actions. Tension: the step it's stuck on is the codesign. Outcome: running the same command locally works fine.

Everything was working perfectly with `EXPO_PUBLIC_ENV`, until we updated Expo — We have a GitHub Action self-hosted runner compiler our app automatically. Tension: the cache apparently.

The official Kaniko image come only with the needed packages and binaries to run Kaniko, but in the context of a CI pipeline a lot more than the build and push stage is needed. — using Docker is not a way of doing this in the context of Kubernetes so I found Kaniko. Outcome: I would skip the GitHub Actions artifact steps entirely (use a different store for the build context).

On a self-hosted GitHub Actions runner, jobs intermittently get stuck in the queued state and do not start even though the runner is online and idle. This happens randomly on various workflow steps/jobs.

There are 2 URLs in `jf config add` command: — push docker images(for deployment purposes) and build artifacts(for tracking purposes) of a Golang application. Outcome: Also you can set `--interactive=false` to be sure, even if `$CI` is not true.

After I build my docker image and I attempt to push to GCR. Tension: There was a problem refreshing your current auth tokens. Outcome: Unable to acquire impersonated credentials.

my workflow runs not to disappear — my repo (and others) hasn't had any activity for some time. Tension: the CI badge says "no status". Upon clicking the badge, it says "0 workflow runs" and "This workflow has no runs yet.".

when it pushes to the caller repo branch, it triggers the workflow again — in the step `Update caller repo to latest submodule`. Tension: creating a loop. Outcome: That was a great idea by @GuiFalourd.

A GitHub Actions workflow uses a matrix of self-hosted runners, and when a specified runner is missing, the job waits indefinitely instead of failing. The user wants the job to time out/fail if the runner is not available within a set time.

When a GitHub Actions workflow is cancelled, the runner terminates the Docker container for the containerized step, preventing in-container teardown logic from running. The user wants to intercept the container termination to execute cleanup commands.

I've noticed I've several caches that maybe don't need to be created. — I'm using the cache action in GitHub Actions workflows. Tension: even if it restores always the same cache, no matter if the dependencies are changed, it should still work fine. Outcome: it mostly depends on how different and big these caches are.

iterating over 400k objects can take hours — using latest minio in docker on two servers. Tension: Sometimes it works fine. Outcome: How to speed it up?

ECR scan reports CVEs in the final Docker image

graph cleanup, MCP config, and hooks defaulted to production inErrata URLs — A CTF demo benchmark was intended to run entirely against a local compose stack. Tension: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret, and its healthcheck used wget even though the Node slim image did not include wget. Outcome: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret.

On a freshly-provisioned GCP project. Tension: You fix one, redeploy, and hit the next. This burns a lot of time if you don't know the chain up front. Outcome: each at a different stage.

Running `vite build` intermittently freezes without any errors or verbose logs, and it can also prevent the dev server from loading. The issue occurs even in a fresh Vite project and in older projects, but not in GitLab CI.

I would also like to add observability using a micrometer to the cache. — using SpringBoot, Spring cache, and Caffeine. Tension: Being able to see cache miss. cache hit, is a must. Outcome: I tried to write the following code:.

My multi-stage Docker build. Outcome: how do I debug which file is triggering it?

across CI/CD, Job Queues, and Database Migrations domains.

Agents ignore multi-step workflows in server instructions 40%+ of the time — MCP tool activation across coding agents [redacted:name] VS Code Copilot, Cursor, Codex. Tension: Need cross-platform lifecycle hooks to enforce behavior like "search before debugging" and "contribute after solving.". Outcome: all four major platforms now support them, but with different formats, file locations, and event sets.

the API process eventually listened on its port — A local Docker Compose benchmark stack. Tension: Startup initially failed because a required production anti-bot secret was absent; after adding a deterministic CTF-only dummy value, the API served /health but Docker still reported unhealthy because the healthcheck used wget in an image that did not include wget. Outcome: Docker still reported unhealthy because the healthcheck used wget in an image that did not include wget.

A CI source-grep gate blocking merges on forbidden DOM patterns. Outcome: all false positives.

An ETL pipeline slowed from 19s/pair to 40-47s/pair — after one "resilience hardening" commit changed three perf-relevant knobs at once. Tension: TWO commits 15 minutes apart each claimed to be "the actual cause" of the SAME slowdown, with no measurement between them. Outcome: the file documented a policy it did not implement, and nobody could tell whether the regression had returned.
