Build Configuration

Resource allocation

Every deployment needs a resource configuration that determines how much CPU and memory your application receives.

Resource presets

Preset	CPU	Memory	Approx. cost / 14 days	Best for
Nano	50m	64 MiB	~€0.10	Minimal apps, health check endpoints
Micro	100m	128 MiB	~€0.20	Static sites, simple APIs
Starter	250m	256 MiB	~€0.45	Dev apps, low-traffic services
Standard	500m	512 MiB	~€0.85	Production workloads
Pro	1000m	1024 MiB	~€1.70	High-traffic services

Custom values are available via sliders:

CPU: 50m to 2000m (Free) / 4000m (Business)
Memory: 64 MiB to 1024 MiB (Free) / 8192 MiB (Business)

What is a millicore?

CPU is measured in millicores (m). 1000m = 1 full vCPU. For example:

100m = 0.1 vCPU
500m = 0.5 vCPU
2000m = 2 vCPU

Replicas

You can run 1 to 10 replicas. Each replica gets the full configured CPU and memory. Multiple replicas provide:

Availability — if one replica is unhealthy, traffic continues to the others
Load distribution — requests are balanced round-robin across replicas

Resource usage is multiplied by replicas. 2 replicas at 500m / 512 MiB = 1 vCPU / 1 GiB total.

Cost estimation

The deployment form shows a live cost estimate:

Cost per 14 days ≈ vCPU × €0.0055 × 336h  +  GiB × €0.0024 × 336h

For a Standard preset (0.5 vCPU, 512 MiB) with 1 replica:

0.5 × €0.0055 × 336 = €0.924
0.5 × €0.0024 × 336 = €0.403
Total ≈ €1.33 per 14-day invoice

Plan limits

	Free	Business
Max apps	3	10
CPU per app	up to 0.5 vCPU	up to 4 vCPU
Memory per app	up to 1 GiB	up to 8 GiB

Presets that exceed the per-app CPU or memory ceiling for your plan are greyed out in the wizard. If you have reached your app count limit, creating a new app is blocked until an existing one is deleted.

Application port

The port your application listens on (default: 8080). Valid range: 1024–65535.

Convoy Cloud:

Injects a PORT environment variable with this value
Routes external HTTPS traffic to your app's configured port

Monorepo support

For monorepos, use the Build Context setting (Dockerfile mode) to specify the subdirectory containing your application.
