Cert Object Backup and Restore

This small script is to back up Kubernetes certificate objects that are used by the cert-manager. The script will also restore by creating the backed-up certificate objects in the given Kubernetes namespace.

Installation

After cloning the repo you will need to add the yaml library

python setup.py install

This script uses the pyyaml library. If for some reason install fails you can always just install pyyaml with pip

pip install pyyaml

You can find more information on this library at PyYaml

Usage

For backing up cert objects you need to give 3 parameters: namespace, k8 config path, and the key word backup.

python backup.py <namespace> backup <k8_config_path>

example

sudo python backup.py liquid-web-cert-manager-staging backup /Users/myusername/.kube/config-dev

For restoring the cert object after a back up you need to give 3 parameters: namespace, k8 config path, and the key word restore. Note: If you have multiple backup files there is no guarantee it will restore from latest. Only one backup file should be kept in back up path.

python backup.py <namespace> restore <k8_config_path>

example

sudo python backup.py liquid-web-cert-manager-staging restore /Users/myusername/.kube/config-dev

All certificate objects will be backed up to the following path in yaml form.

/var/lib/backup/<cert_manager_backup_timestamp>/certs

Other

This script uses kubectl and it assumes that you have kubectl already installed and its context configured to the kubernetes profile you wish to connect to.
