Resource Limits

Every app on Zerokie runs with resource limits to ensure isolation and predictable performance. You can customize these limits to match your workload.

Default limits

If you do not specify limits, apps are created with:

Resource	Default
CPU	256 MHz
Memory	512 MB

Setting custom limits

Use the --cpu and --memory flags when creating an app:

zerokie apps create \
  --name my-api \
  --image my-registry.com/my-api:latest \
  --port 3000 \
  --cpu 512 \
  --memory 1024

• --cpu sets the CPU limit in MHz.
• --memory sets the memory limit in MB.

Choosing the right limits

Workload	Recommended CPU	Recommended Memory
Static site / proxy	256 MHz	256 MB
Node.js API	512 MHz	512 MB
Java / .NET service	512-1000 MHz	1024 MB
Data processing	1000 MHz	2048 MB

Start with the defaults and increase if your app shows signs of resource pressure (slow responses, OOM kills).

What happens at the limit

• CPU: Your app is throttled when it exceeds the CPU allocation. It continues running but responds more slowly.
• Memory: If your app exceeds its memory limit, the container is killed and restarted automatically.

Next steps

• Pass configuration values with environment variables.
• See the full CLI Reference for all available flags.
