Create etcd backup
This SOP should be followed in the following scenarios:
- When the need exists to create an etcd backup.
- When shutting a cluster down gracefully.
Steps
- Connect to a master node
oc 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 admin machine.
scp -i <ssh_key> core@<node_name>:/home/core/assets/backup/* ocp_backups/
