Description
When attempting to deploy the Gitea shared service or Gitea workspace service in a new environment, deployment fails with:
ProvisionNotSupportedForRegion: Provisioning in requested region is not supported.
Your subscription might not have access to create a server in the selected region.
This occurs because MySQL Flexible Server (required by both Gitea templates) is subject to subscription-level quota restrictions in UK South. The error affects all SKU tiers — Burstable (B_Standard_B2s), General Purpose (GP_Standard_D2ds_v4), and Business Critical.
Affected templates
templates/shared_services/gitea/
templates/workspace_services/gitea/
Impact
Existing deployed Gitea instances are unaffected — this only affects new deployments
PROD Gitea is currently healthy and not at risk
DEV environment cannot deploy Gitea until quota is resolved
Workaround
Select GP | 8GB 2vCores in the TRE UI when deploying — this uses General Purpose tier which has better availability, but is still subject to the same subscription restriction
If neither tier is available, raise a quota request via Azure Portal: Help + Support → New support request → Service and subscription limits → Azure Database for MySQL Flexible Server → Region access → UK South
To verify quota availability on a subscription:
bashaz mysql flexible-server list-skus --location uksouth --output table
An empty result confirms MySQL Flexible Server is fully restricted on that subscription.
Notes
- This is an Azure subscription capacity issue, not a bug in the TRE templates
- A future improvement could be to surface a clearer error message in the TRE UI when this quota restriction is hit
- Consider documenting this as a prerequisite check before spinning up a new TRE environment
