This page gives an overview of PostBox, describing its current status, where and how it's developed and deployed, and who is responsible for maintaining it.


PostBox uses technology, coding standards, and deployment methodologies which are not endorsed by the TDA and not standard practice for the DevOps team.

How and where Postbox is deployed

Deployment is via our standard terraform deployment CI pipeline.

Deploying a new release

Making a new release of the application is done via release automation. In short: each commit to the web app's main branch builds and pushes a Docker image to GCR. An MR can then be raised within the infrastructure repository to deploy a given image by SHA. Once merged, the main GitLab pipeline will allow deployment to production via the "play" buttons in the CI pipeline. An automated deployment to staging will be completed as part of this pipeline.


Monitoring is configured as per our standard Google Cloud Run application module.

Access Management

Access management is managed internally within the application, with the application holding a list of clients who are able to access the API alongside their credentials.

Service Management

The service owner for PostBox is Nick Stocks

The service manager for PostBox is Andrew Crook

The tech lead for PostBox is vacant until redevelopment can be completed.
