Best VPS for Docker apps

Docker makes deployment cleaner, but containers still share the same RAM, CPU, disk, and network. A 2GB VPS is the useful starting point for a small Compose stack.

Minimum

1GB RAM for one or two light containers; 2GB RAM is the useful floor.

Recommended

2 vCPU / 2GB RAM / 40GB+ SSD for a small app stack.

Upgrade when

Upgrade when databases, queues, search, or multiple apps share the box.

What matters for Docker

One app container may be tiny. A real stack often adds PostgreSQL, Redis, a reverse proxy, backups, monitoring, and logs. Count the whole stack before choosing a VPS.

Recommended provider fit

  • Hetzner CX22
  • Vultr 2GB
  • Linode 2GB
  • DigitalOcean Basic 2GB

Buying rule

Choose 2GB RAM for a small stack. Choose 4GB RAM if the stack includes databases plus more than one production app.

Docker VPS FAQ

Is 1GB RAM enough for Docker?
It is enough for one or two light containers. A small real-world Docker Compose stack usually feels better on 2GB RAM.
What makes Docker VPS sizing hard?
People count the app container but forget PostgreSQL, Redis, reverse proxy, logs, backups, and monitoring. Size the whole stack.
When should I choose 4GB RAM for Docker?
Choose 4GB RAM when you run multiple production apps, databases, search, queues, or anything that should survive traffic spikes.
