Chapter 9. Disconnected environment
Disconnected environment is a network restricted environment where Operator Lifecycle Manager (OLM) cannot access the default Operator Hub and image registries, which require Internet connectivity.
Red Hat supports deployment of OpenShift Data Foundation in disconnected environments where OpenShift Container Platform is installed in restricted networks.
To install OpenShift Data Foundation in a disconnected environment, refer to the steps in the Using Operator Lifecycle Manager on restricted networks chapter of Operators guide in OpenShift Container Platform documentation.
When you install OpenShift Data Foundation in a restricted network environment, apply a custom Network Time Protocol (NTP) configuration to the nodes, because by default, internet connectivity is assumed in OpenShift Container Platform and chronyd is configured to use *.rhel.pool.ntp.org servers. See Red Hat Knowledgebase article and Configuring chrony time service for more details.
