Summary	The deployment of some components to our preprod environment was failing due to apparent memory constraints
Impact	No new versions of these components could be deployed for a short period of time (~1 day)

Non-technical Description

Trigger

Deployment of run-of-the-mill component updates (and subsequent reversion to known-good builds) failed

Temporary fix: increase container memory for the affected components from 0.5GB to 1GB

All times in BST unless indicated

13 Jun 2023: 14:39 - Failed deployment for tis-trainee-ndw-exporter reported in #notifications-deployments Slack channel, closely followed by failed deployments for tis-trainee-credentials and tis-trainee-user-management.
13 Jun 2023: 16:13 - Reverts to the updates to these components also fail to deploy.
14 Jun 2023: 11:25 - Redeploy of tis-trainee-ndw-exporter attempted with ECS task configured with 1GB memory instead of 512MB
