Downloading side car images

The following table lists the side car images for the CSI plugin and fencing containers. You must download the CSI plugin-related images from https://console.cloud.google.com/gcr/images/k8s-artifacts-prod/asia/sig-storage and the fencing-related images from https://hub.docker.com/r/kvaps/kube-fencing-agents.

Note:

Perform these steps if you are manually tagging images instead of using setup_vtas_registry.sh for tagging images.

You must pull these images, tag correctly, and subsequently push the tagged images to the custom registry. The commands are in the following format.

  • Pulling the image

    docker pull <source from the above table>:<tag from the above table>

  • Correctly tagging the image

    docker tag <source from the above table>:<tag from the above table> <Required tag from the above table>

  • Pushing the image

    docker push <Required tag from the above table>

An example of commands for csi-snapshotter is as under -

  • docker pull k8s.gcr.io/sig-storage/csi-snapshotter:v8.4.0

  • docker tag k8s.gcr.io/sig-storage/csi-snapshotter:v8.4.0 <IP address of custom registry>:<port number>/csi-snapshotter:v8.4.0

  • docker push <IP address of custom registry>:<port number>/csi-snapshotter:v8.4.0

Run these commands on all the images.
