Should your application container run out of available disk space you can increase the disk space allocated to your application container via the disk key in your .platform.app.yaml configuration file.
For instance, it might look as per below.
# The size of the persistent disk of the application (in MB).
For your services containers e.g. MySQL/Redis/Elasticsearch, etc. you can increase the disk key for the affected service in your .platform/services.yaml configuration file instead.
In case the total allocated disk between your application container and your services containers exceeds the total plan limit this will be highlighted in your deployment log, for instance as per below.
Error: Resources exceeding plan limit; disk: 8192.00MB > 5120.00MB; try removing a service, or add more storage to your plan
In such cases, you have the option to increase your plan’s storage limits within your project settings.
We recommend enabling health notifications for low storage alerts in your integration settings.
