How to move a containerd image to different namespace?
Moving a containerd image to a different namespace involves exporting the image from the source namespace and importing it into the target namespace. Here are the general steps to accomplish this:
Export the image from the source namespace:
shellcontainerd ctr images export <source-namespace>/<image-name>:<image-tag> <output-file>
Replace
<source-namespace>
,<image-name>
,<image-tag>
, and<output-file>
with the appropriate values. This command exports the image to a tar file.Import the image into the target namespace:
shellcontainerd ctr images import --base-name <target-namespace>/<image-name>:<image-tag> <input-file>
Replace
<target-namespace>
,<image-name>
,<image-tag>
, and<input-file>
with the appropriate values. This command imports the image from the tar file into the target namespace.Optionally, remove the image from the source namespace:
shellcontainerd ctr images remove <source-namespace>/<image-name>:<image-tag>
Replace
<source-namespace>
,<image-name>
, and<image-tag>
with the appropriate values. This command removes the image from the source namespace, freeing up disk space if needed.
Please note that these steps assume you have the containerd
command-line tool (ctr
) installed and configured properly. Adjust the commands according to your specific containerd setup and namespace names.
Also, keep in mind that moving an image to a different namespace does not affect any running containers that were created from that image. It only affects the availability of the image in the respective namespaces.
Ensure you have the necessary permissions and access rights to perform these operations, as they typically require administrative or root privileges.
