We stopped worshiping containers. We started thinking again.

Hook We did the unthinkable. We removed Docker from our production stack — and nothing exploded. No outages. No rollback chaos. Not even a single missing dependency. Just a quieter CI pipeline… and faster deploys.

This isn't a "Docker hate post." It's a reality check for engineers who mistake convenience for necessity.

1. The Docker Delusion

For years, we treated Docker like oxygen. "Immutable builds." "Environment parity." "Portable infrastructure."

It all sounds good — until you realize most of your services don't need any of that.

Docker was built to solve complexity. But somewhere along the way, it became the complexity.

2. The Experiment

We had a small Java service:

  • Spring Boot (fat JAR, self-contained)
  • Runs behind Nginx
  • Has its own VM with systemd
  • No multi-tenancy, no Kubernetes

In other words: the perfect place to ask "Do we really need Docker here?"

So we tried something insane:

  • Removed the Dockerfile.
  • Replaced our image with a simple .tar.gz artifact.
  • Deployed it using a 40-line Bash script and systemd.

And it worked.

3. The "Deployment" (If You Can Still Call It That)

#!/usr/bin/env bash
set -euo pipefail

APP=myservice
VERSION=$1
URL="s3://artifacts/$APP-$VERSION.tar.gz"
echo "[1/4] Downloading package..."
aws s3 cp "$URL" /tmp/$APP.tgz
echo "[2/4] Deploying..."
tar -xzf /tmp/$APP.tgz -C /opt/$APP
systemctl daemon-reload
systemctl restart $APP
echo "[3/4] Health check..."
curl -fsS localhost:8080/actuator/health >/dev/null && echo "Healthy ✅"

That's it. No Docker daemon. No image layers. No YAML-induced trauma.

4. What Changed (and What Didn't)

None

5. The "Why It Worked" Part

  1. Our app was already portable. It didn't depend on system libraries. A single JAR runs anywhere with a JVM.
  2. Our infra was static. We weren't scaling thousands of containers — just a handful of dedicated VMs.
  3. Our CI/CD already produced clean artifacts. The .tar.gz was versioned and immutable, just like a Docker image.
  4. Systemd is underrated. You get restart policies, health checks, cgroups v2 limits — all the "container" features without the extra abstraction.

6. What We Gained

  • Less cognitive load. No more Dockerfiles, registries, or broken cache layers.
  • Fewer moving parts. No dockerd daemon to babysit.
  • Real transparency. ps aux actually shows your app — not some opaque container ID.
  • Smaller attack surface. No exposed Docker socket, no privileged runtime.

7. What We Lost (and Didn't Miss)

  • No "image tagging" hell.
  • No docker system prune panic moments.
  • No "works on my container" surprises.
  • We did lose instant portability — but we didn't need it. Our fleet was homogeneous by design.

8. So, Is Docker Useless?

Not at all. Docker shines when:

  • You have dozens of microservices.
  • You need isolation between tenants or teams.
  • You rely on Kubernetes.
  • You need consistent local development environments.

But for small to mid-scale deployments? Docker might be an elegant waste of time.

9. The Hard Truth

Most teams don't need Docker. They use it because everyone else does. Because tutorials do. Because "real engineers ship containers."

We're not smarter for ditching Docker — we're just brutally honest about our needs.

10. Final Thoughts

Sometimes engineering isn't about adopting more layers. It's about removing the ones you don't need.

Our system is simpler. Our deploys are faster. And no one has to remember the difference between --rm and --detach.

Docker didn't break — we just outgrew it.

🥃 Afterword: The Night We Killed Docker

It was 2 a.m. We were half-asleep, half-mad — watching our CI pipeline choke on yet another layer cache. Someone said, "What if we just… didn't?" We laughed. Then we did it.

One rm -rf Dockerfile later, the servers came back up. No alarms. No angry pings. Just quiet logs and CPU graphs that looked… peaceful.

That night, we realized something they never teach you in tech conferences:

Sometimes engineering isn't about building stronger walls — it's about knowing when to take the damn walls down.

We poured whiskey into coffee mugs, looked at the dashboard, and one of the seniors said: "You know, maybe real DevOps was the friends we un-containerized along the way."

Everyone laughed. Because for the first time in months, production was silent. No alerts, no docker ps. Just code — running free.
