Load harbor offline tar.gz into k3s' containerd

[cwrx777]

Hi, I want to install harbor in an airgap environment without docker.
My environment is RHEL 8.9 and is running k3s, which is bundled with containerd.

It's going to be a long process but my first thought is to import/load the container images into containerd,then use the harbor/helm chart to load the images.

So I downloaded the offline installer package from harbor release page,
extract the content, and I found a harbor.vx.y.z.tar.gz.

However, when I performed ctr -n k8s.io import image harbor.vx.y.z.tar.gz, it shows error ctr: archive/tar: invalid tar header.

I tried extracting the tar.gz by using tar -xvf harbor.vx.y.z.tar.gz but the extracted files are like the following:

fcfe6c0f0ce0617cb8330b91f550419923a4e4b4fee5861e5f3349ab038ecd78/
fcfe6c0f0ce0617cb8330b91f550419923a4e4b4fee5861e5f3349ab038ecd78/VERSION
fcfe6c0f0ce0617cb8330b91f550419923a4e4b4fee5861e5f3349ab038ecd78/json
fcfe6c0f0ce0617cb8330b91f550419923a4e4b4fee5861e5f3349ab038ecd78/layer.tar
manifest.json
repositories

Any help is appreciated..

Hi all,

Answering my own question.
The harbor.vx.y.z.tar.gz can be copied into the ${K3S_DATADIR}/agent/images. and the images in that folder will be imported into containerd when k3s is restarted.
