-
When shutting a cluster down gracefully.
Take etcd backup
-
Connect to the
os-control01
node associated with the ENV. -
Use the
oc
tool to make a debug connection to a controlplane nodeoc debug node/<node_name>
-
Chroot to the /host directory on the containers filesystem
sh-4.2# chroot /host
-
Run the cluster-backup.sh script and pass in the location to save the backup to
sh-4.4# /usr/local/bin/cluster-backup.sh /home/core/assets/backup
-
Chown the backup files to be owned by user
core
and groupcore
chown -R core:core /home/core/assets/backup
-
From the admin machine, see inventory group:
ocp-ci-management
, become the Openshift service account, see the inventory hostvars for the host identified in the previous step and note theocp_service_account
variable.ssh <host> sudo su - <ocp_service_account>
-
Copy the files down to the
os-control01
machine.scp -i <ssh_key> core@<node_name>:/home/core/assets/backup/* ocp_backups/
