Jobs resource limitationsLink to this anchor
| Resource | Limit | Scope |
|---|---|---|
| Number of job definitions max | 1000 | Organization |
| Max parallel jobs | 400 | Organization |
| Max ephemeral storage | 10 GB | Job run |
| CPU max | 6 vCPU | Job run |
| Memory max | 16 GB | Job run |
| Timeout | 24h | Job run |
Default values for CPU and memory limitsLink to this anchor
When the job vCPU and/or memory are not provided by the client, these default values are automatically used:
| Resources | Default value |
|---|---|
| CPU | 1120 mvCPU |
| Memory | 2048 MB |
ArchitectureLink to this anchor
Image target platform must be: linux/amd64.
For example, if you build an image using an ARM CPU, such as Apple Silicon M series, your image will be in the arm64 architecture, and you will have an error message during deployment.
You must ensure that you build your image to target amd64 architecture, to achieve this there are multiple solutions:
- You can use the following docker command:
docker build --platform linux/amd64 ., or - You can use an Instance with
amd64architecture to run your builds.
Ports restrictionsLink to this anchor
In order to ensure the proper functioning of the product, we restrict the use of certain ports and environment variables.
- Blocked ports:
- 25: Due to potential abuse (spam), no outbound traffic is allowed through this port, except from Scaleway Transactional Email SMTP servers.
- 465: Due to potential abuse (spam), no outbound traffic is allowed through this port, except from Scaleway Transactional Email SMTP servers.
Dedicated IPLink to this anchor
Not available: Serverless products are designed to abstract away infrastructure management, to be easily scalable, and to be cost-efficient and simple. So dedicated IPs are not supported for this product.
Private Network and Virtual Private Cloud (VPC) compatibilityLink to this anchor
Refer to the dedicated FAQ for more information on Serverless Jobs compatibility with Private Networks and Virtual Private Cloud (VPC).
Image sizeLink to this anchor
We recommend keeping your image size below 2 GB to ensure faster deployment.
Tips for keeping image size downLink to this anchor
- Use lightweight distribution like Alpine
- Minimize layers and unnecessary dependencies
- Clean up temp files and cache (e.g.,
rm -rf /var/lib/apt/lists/*in Debian-based images) - Use multi-stage builds to keep only runtime essentials. Example
