Artifacts and Deployment

This page is reference material for the Migration Procedure and the planning overview in What to Know Before Migrating.

It covers the GridGain distribution, the build coordinates to update for each language, Docker changes, and module and extension availability.

Distribution

GridGain ships as a ZIP archive, a Docker image, cloud images for AWS, Azure, and Google Compute, a Kubernetes operator, and RPM/DEB packages. Download links and per-format instructions are in Installing and Starting GridGain.

Check the supported Java versions before you migrate. GridGain 8.9+ runs on Oracle JDK 8, 11, or 17, and on 21 in 8.9.10 and later. Starting with 8.9.17, full-text search and vector search require JDK 11 or later, so Java 8 does not carry the full feature set forward. For the complete platform requirements, see Installing and Starting GridGain.

GridGain Ultimate Edition is licensed software, so it includes a gridgain-license.xml file at the install root. Replace this file with the production license issued by GridGain, or point to a custom location with GridGainConfiguration.setLicenseUrl(…​) (a filesystem path, an HTTP/FTP URL, or a ConfigMap if using Kubernetes). Ultimate features will not start with a missing or expired license.

Build Coordinates

For each language you use, update the package or repository dependency as shown below. Artifact IDs (ignite-core, ignite-spring, and so on), Java and C# imports, and C++ namespaces and headers remain the same.

Language From To

Java (Maven/Gradle)

groupId org.apache.ignite (Maven Central)

groupId org.gridgain (GridGain Nexus), plus the gridgain-ultimate dependency

.NET (NuGet)

Apache.Ignite.*

GridGain.Ignite.*

Python (pip)

pyignite

pygridgain

Node.js (npm)

apache-ignite-client

@gridgain/thin-client

C++

No change

For the full dependency snippet and repository details, see the per-language Quick Start guides.

Docker

Skip this section if you do not run GridGain in containers.

  • IGNITE_HOME changes from /opt/ignite/apache-ignite to /opt/gridgain. Update volume mounts, scripts, and configs that reference the old path.

  • The container runs as a non-root gridgain user (UID 10000). Verify file ownership and permissions on mounted volumes.

  • The GridGain image’s EXPOSE directive does not include ports 10800 (thin client) or 8080 (REST). Publish them explicitly with docker run -p when you need to reach those endpoints from outside the container.

  • wget is not included in the image. Use curl instead.

For the complete instructions on available Docker images and installation, see Installing Using Docker.

Modules and Extensions

Skip this section if you do not use any ignite- modules or extensions beyond the core libraries.*

  • ignite-calcite is not available. Use the H2 engine (default).

  • ignite-json is not available. Handle JSON-to-BinaryObject REST conversion with a custom ConnectorMessageInterceptor instead.

  • Most ignite-*-ext extensions from Maven Central are compatible with GridGain; several have built-in GridGain equivalents (AWS, GCE, Spring, ZooKeeper IP finder).

  • Incompatible extensions with no equivalent: ignite-azure-ext (use DNS-based discovery), ignite-performance-statistics-ext (use JMX/APM), ignite-spring-session-ext, and ignite-storm-ext.
