Deploy Docker Containers Without Kubernetes
CLI-based deployment platforms let you deploy a Docker image to production with a single command. No cluster setup, no YAML manifests, no ingress controllers. You get a live URL with SSL, scaling, and monitoring included.
The problem
You have a Docker image. You want it running in production with a URL, SSL, and monitoring. The internet says you need Kubernetes. But Kubernetes is a container orchestration system designed for thousands of containers across hundreds of nodes. For most applications, it is massive overkill.
When Kubernetes is overkill
Kubernetes makes sense at scale: dozens of microservices, auto-scaling across regions, complex networking policies. For a single API, a web app, or a small set of services, Kubernetes adds weeks of setup, ongoing maintenance, and cognitive overhead. Most applications never need it.
What you actually need
For most Docker deployments, you need: a way to run the image, a URL to access it, SSL certificates, basic scaling (1-3 replicas), environment variables, and log access. That is it. No service mesh, no Helm charts, no kubectl debugging.
CLI deployment vs docker-compose
docker-compose runs containers on your local machine or a single server. It does not provide SSL, custom domains, scaling, or monitoring. CLI deployment platforms handle all of that. You provide the image reference, the platform handles everything else.
Approaches compared
Platform CLI (CreateOS, Fly, Railway)
Pros
- One-command deploy
- SSL and domains included
- Built-in scaling
- No infrastructure to manage
Cons
- Platform dependency
- Less control than raw infrastructure
Best for: Teams that want to ship, not manage infrastructure
docker-compose on a VPS
Pros
- Full control
- Cheap for small workloads
Cons
- Manual SSL setup
- No auto-scaling
- Server maintenance required
- No built-in monitoring
Best for: Developers comfortable with server administration
Kubernetes (EKS, GKE, AKS)
Pros
- Enterprise-grade orchestration
- Auto-scaling across regions
- Extensive ecosystem
Cons
- Weeks of setup
- Ongoing cluster maintenance
- Steep learning curve
- Expensive for small workloads
Best for: Large organizations with dedicated DevOps teams
Deploy Docker with CreateOS CLI
Here is how to do it step by step using CreateOS CLI.
Install the CLI
Single binary for macOS and Linux.
Link your project
Link to an image-type project on CreateOS.
Deploy the image
Any valid Docker image reference works. Docker Hub, GHCR, ECR, or any public registry.
Add a custom domain
Get DNS records to configure. SSL is provisioned automatically.
Scale if needed
Adjust replicas, CPU, and memory. Before/after diff shown.
