Red Hat build of MicroShift

Clean all data and keep 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/microshift data directory
Delete OVN-K networking configuration

This option deletes all MicroShift data and user workloads. Use with caution.

Prerequisites

You are logged into MicroShift.
You have filed a support case.

Procedure

Clean up all data and user workloads when retaining the MicroShift container images by running the following command:

$ sudo microshift-cleanup-data --all --keep-images
