What’s a simple managed service for hosting a Docker container?
Asked by
local history volunteer
I'm working on a small side project and want to deploy a Docker image without managing a VPS, server updates, networking, or security configuration myself. I'm not looking for automatic scaling, edge runtimes, or a large serverless platform. Ideally, I'd pay around $5–$10 per month for a service that runs my existing container with minimal changes. Services such as Vercel and Cloudflare seem to encourage using their own frameworks or deployment models, and I'd rather keep the application portable so I can move it to another host later. What managed Docker hosting options would fit this use case?
Answers
Fly.io could work well for this. It’s pay-as-you-go, and a small instance can cost around $5 per month or less, especially if you configure it to stop when it isn’t being used. Deployment mainly involves a Dockerfile and a small configuration file, so you don’t have to rewrite the application for a proprietary framework.

DigitalOcean has managed container and application-hosting options, although the cost may be closer to $10–$15 per month depending on the setup. It’s a good option if you prefer a more conventional cloud provider and predictable infrastructure.

Railway, Heroku, and Fly.io are all reasonable choices for a simple container deployment. Fly.io in particular handles much of the setup through its command-line tool, while still letting you deploy a fairly standard Docker image.

A Docker-ready VPS reduces the initial setup, but it doesn’t eliminate server administration. You’d still be responsible for updates, firewall rules, backups, and security. If avoiding all of that is the main goal, a platform such as Fly.io or Railway is probably a better fit than a plain VPS.

Another approach is to rent a small Hetzner VPS and install Coolify. Coolify provides a friendly deployment interface and takes care of much of the application management, while still giving you the flexibility of Docker. You would still have some responsibility for the underlying server, though, so it isn’t completely hands-off.
