* Lower limits may apply before account verification. Contact our support team if you have any questions.
** Total container memory is the sum of the memory allocated to all your containers at their maximum Scale.

These limits are enforced as Organization quotas.
During the execution of the container, if the limits are exceeded, a restart occurs.
Configuration Restrictions
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.
- Unavailable custom ports
Do not make your containers listen on these ports which are used by our service.
- 8008
- 8012
- 8013
- 8022
- 9090
- 9091
- Reserved environment variables:
PORT: Port on which your server should listen to (the default value is 8080)SCW_*: Reserved for product configuration (for example: token validation)
Default values for CPU and memory limits
When container CPU and/or memory are not provided by the client, these default values are automatically used:
| Resources | Default value |
|---|---|
| CPU | 1000 mvCPU |
| Memory | 2048 MB |
Architecture
Scaleway Containers only supports amd64 architecture for
images.
For example, if you build an image using an ARM CPU, such as Apple Silicon, your image will be in the arm64 architecture, and you will have an error message during deployment.
You must ensure to build your image to target amd64 architecture.
