ICR Extended Maintenance Images Update to Latest Release

In general, the InterSystems Container Registry (ICR)Opens in a new tab publishes one container image for each extended maintenance (EM) release of an InterSystems product. The image is kept up-to-date so that it contains the most recent maintenance release for that EM version. For example: when InterSystems distributes a new maintenance release for InterSystems IRIS 2024.1, the iris:2024.1 image tag is updated so that it produces a container which features the newest maintenance release; images which feature previous maintenance release versions cease to be available through the ICR.

As a result, containerized applications which are deployed using the ICR image for an EM release may be subject to unexpected updates. This can cause problems from one deployment to the next, especially if the InterSystems container did not stop gracefully.

For situations where it is necessary to ensure that a containerized application’s InterSystems product version remains consistent across deployments, InterSystems recommends that organizations maintain their own InterSystems IRIS images within a private registry. You can then deploy your containerized applications using images from your organization’s private registry, instead of the ICR.
