IBM Cloud Pak® for Integration is a Kubernetes-native product. The container images for Cloud Pak for Integration are available from online container registries. If your cluster has access to the internet, the registries can be used for production deployment.
IBM Cloud Pak for Integration uses image digests to identify the correct images to use from the container registry. This provides an additional layer of security, as the image can be verified using the cryptographic hash. Images are also signed, and the signature can be verified. For more information, see Verifying image signatures.
If your cluster is not connected to the internet, or your network does not allow access to the container registries for online use, you can mirror the images used for Cloud Pak for Integration to your own registry and configure your OpenShift cluster to use those images instead. For more information, see Mirroring images for an air-gapped cluster.
