55 Production Deployment Jokes Every Release Engineer Knows

"It's a small change." Four words, one outage.

Deploy at 4:55 p.m. on Friday. What could possibly happen between now and Monday.

The PR description said: "Minor refactor." It was 2,400 lines.

"I tested it locally." Production is a different country.

We have a deploy freeze. Everyone has at least one exception.

The pipeline went green. The service went red. These are unrelated.

"Did you rollback?" "To what?"

Hotfix: the deploy you ship to fix the deploy you shipped twenty minutes ago.

Feature flag default: off. Feature flag in production: on. Nobody remembers who flipped it.

The deploy lock was held by someone on vacation.

"Why did the build pass?" "Because the tests passed." "Why did the tests pass?" "Because they don't test that."

Blue-green deployment in theory: seamless cutover. Blue-green deployment in practice: green is on fire, blue is wedged, both are serving traffic.

I clicked deploy. The button said "deploying." It said that for 47 minutes. It is still saying it.

"Don't deploy on Fridays." The most ignored advice in software.

The release notes are one line: "Bug fixes and improvements." The diff is 3,000 lines.

The deploy succeeded. The service stopped. The monitors did not alert. The users alerted.

Canary deployment: 1% of users get the experience first. They are the 1% chosen to discover that the database migration was missing.

"It worked in staging." Staging is a lovely place. Nothing real lives there.

We have CI/CD. We also have a person who runs the deploy by hand on Wednesdays for reasons nobody remembers.

"Who approved this PR?" The approver had two hours of sleep and was attending a meeting on mute.

Rollback procedure: step one, panic. step two, find the previous tag. step three, discover the tag does not exist. step four, panic differently.

"We follow trunk-based development." The trunk is on fire and nobody is checking in.

The deploy was at 3:00 p.m. The incident started at 3:01 p.m. The denial started at 3:02 p.m.

The deploy pipeline has 14 stages. It failed at stage 13. The error message is: "unknown."

"Did you bump the version?" "Did I need to?" "Yes."

Production access controls: strict, audited, multi-factor. Production access in practice: everyone has root because of that one time.

The migration was online. The migration was reversible. The migration also was not.

We rolled back. The rollback also broke.

"This deploy doesn't need a postmortem." Five hours later: we're writing one.

Database migration ran in 12 seconds in staging. It has been running for 90 minutes in production. The table has 800 million rows. Nobody told staging.

The release manager said: "Quiet release week." The pager has heard them.

"Just merge it. We'll fix forward." Nobody fixes forward. They roll back at 11 p.m.

Feature flag with 14 conditions, four environments, three user segments, and a kill switch. It's a config file with abandonment issues.

The deploy required a runbook. The runbook required a runbook.

"Have we deployed this before?" "Yes." "Did it work?" "…define work."

Friday deploy. Weekend incident. Monday postmortem. Tuesday Friday deploy.

The DORA metrics looked great. The customers did not.

I added a feature flag. The flag is now production code. It will be there in 2031.

The build cache was stale. The build cache is always stale. The build cache has been stale since the dawn of build caches.

"We need to deploy now." "Why?" "The CEO is demoing in twenty minutes."

The deploy worked. The service degraded. The degradation was the previous deploy waking up late.

Container image size: 4.2 GB. Application size: 12 MB. Nobody knows what the other 4.188 GB does.

"The pipeline is flaky." The flakiness is the only consistent thing about the pipeline.

I deployed to the wrong cluster. I noticed by reading customer tweets.

The CI was green for the first time in three months. We deployed immediately, suspicious of our luck.

"Did anyone test the rollback?" The silence answered.

We have feature flags so we can deploy without users noticing. We also have outages so users notice anyway.

The deploy took eight seconds. The meeting about whether to deploy took ninety minutes.

"This change is backward compatible." With what, exactly.

I deployed an empty change to test the pipeline. The empty change broke production. We still do not know why.

Production parity: the staging environment matches production in exactly the ways that do not matter.

"We use GitOps now." The Git repo has 14 open PRs and three force-pushes from last week.

The cost of a Friday deploy: one weekend. The cost of avoiding a Friday deploy: features shipped a week earlier. Management does the math wrong every time.

The deploy script ended with: "# TODO: handle the rollback case"

Postmortem note: "The deploy was uneventful." Line two of the same postmortem: a forty-minute outage.
