10.2. Enabling Seamless Gear Migration with Node Host SSH Keys

Gear migration on OpenShift Enterprise uses rsync from a broker host. Migrating gears requires SSH access from the broker host to both the origin node host and the destination node host. If available, the /etc/openshift/rsync_id_rsa key is used for authentication, so the corresponding public key must be added to the /root/.ssh/authorized_keys file of each node host. If you have multiple broker hosts, you can either copy the private key to each broker host, or add the public key of every broker host to every node host. This enables migration without having to specify node host root passwords during the process.
