f you’ve been around tech circles long enough, you’ve probably heard someone say:
“Just containerize it. Containers solve all deployment problems.”
It’s a comforting thought — that by packaging your app into a neat little box, you’ll escape the chaos of deployment once and for all. But like most myths, this one hides a harder truth.
Containers don’t erase problems. They shift them.
From “Works on My Machine” to “Works Everywhere”
Let’s give containers credit. They absolutely fix one of the oldest frustrations in software: inconsistent environments.
Before containers, deployments often felt like detective work. Something that ran fine on a developer’s laptop would break spectacularly in production. With containers, your app and its dependencies travel together, ensuring consistency across dev, test, and prod.
That’s a big win. But it doesn’t mean your deployment worries are over.
The Problems That Don’t Disappear — They Transform
When you adopt containers, you don’t get rid of complexity; you move it into new domains.
- Networking gets harder, not easier.Instead of a few static services talking over TCP, you now manage service meshes, overlay networks, DNS resolution inside clusters, and sometimes even cross-cluster communication. Debugging a failed connection in Kubernetes is a very different beast.
- Storage doesn’t magically work.Containers are ephemeral by design. If a pod dies, its local data dies with it. Suddenly, you’re managing persistent volumes, CSI drivers, replication strategies, and figuring out how to back up stateful workloads in a stateless world.
- Observability requires new discipline.Monitoring one or two servers used to be enough. Now you’re dealing with hundreds of short-lived containers. Centralized logging, distributed tracing, and meaningful dashboards aren’t optional anymore — they’re survival tools.
- Security isn’t free.You’ve solved some dependency issues, but introduced new attack surfaces: container escapes, supply chain risks, and misconfigured registries.
Containers as a Mirror, Not a Magic Wand
Here’s the truth: containers don’t fix your infrastructure problems. They make them visible sooner.
- If your networking design is fragile, containers will stress it.
- If your storage approach is fuzzy, containers will expose it.
- If you have no solid observability plan, containers will drown you in blind spots.
Rather than eliminating complexity, containers hold up a mirror. They force you to engineer what you might have ignored before. That’s not a weakness — it’s maturity.
A Better Way to Think About It
Instead of believing the myth, try reframing it:
Containers give us a portable, standardized way to package apps. They don’t remove complexity — they reveal it and demand better solutions.
This mindset helps teams avoid disillusionment. Containers are powerful, but they are a tool in a bigger system, not the cure for all deployment headaches.
Part of the “Infrastructure Myths” Series
This is one of many myths we’re exploring at NotSoStatic. Each post challenges a common assumption in DevOps and cloud engineering:
- Terraform is Always Better Than ClickOps
- More Microservices = More Scalability
- And now: Containers Solve All Deployment Problems
The thread tying them all together is simple: complex systems rarely have simple truths.
