⁠About GeoServer Cloud

GeoServer⁠ is an open-source server for sharing geospatial data. GeoServer Cloud repackages GeoServer as a set of independently deployable and scalable microservices built on Spring Boot and Spring Cloud.

⁠What this image provides

A self-contained GeoWebCache microservice, supporting:

• WMTS, WMS-C, TMS, and KML tile protocols
• Vector tiles (MVT/PBF)
• Truncation and seeding operations
• Pluggable blob stores: local filesystem, S3, Azure Blob, Google Cloud Storage

The image is built on a GeoServer base layer and includes an AOT cache for fast JVM startup. It runs behind the GeoServer Cloud Gateway⁠, which routes /gwc requests to it.

⁠Tags

• <version> — stable release (e.g. 3.0.0)
• <version>-RC<n> — release candidate (e.g. 3.0.0-RC1)
