9.3. Cleaning all data and keeping the container images
You can retain the MicroShift container images while cleaning all data by running the microshift-cleanup-data script with the --all and --keep-images arguments.
Keeping the container images helps speed up MicroShift restart after data clean up because the necessary container images are already present locally when you start the service.
When you run the script with the --all and --keep-images arguments, you perform the following clean up actions:
- Stop and disable all MicroShift services
- Delete all MicroShift pods
- Reset network configuration
-
Delete the
/var/lib/microshiftdata directory - Delete OVN-K networking configuration
This option deletes all MicroShift data and user workloads. Use with caution.
Prerequisites
- You are logged into MicroShift as an administrator with root-user access.
- You have filed a support case.
Procedure
Clean up all data and user workloads while retaining the MicroShift container images by running the
microshift-cleanup-datascript with the--alland--keep-imagesargument, by entering the following command:$ sudo microshift-cleanup-data --all --keep-imagesExample output
