Download artifacts
This section demonstrates how to download the Helm chart and container images to your local machine. These artifacts will be packaged and transferred to the air-gapped environment later.
Create a directory named
offline-kit
.mkdir ./offline-kit
Download the Helm chart into directory
offline-kit
.helm pull oci://ocir.immuta.com/stable/immuta-enterprise --destination ./offline-kit --version 2024.3.9
Extract file
DIGESTS.md
from the Helm chart archive.tar --extract --gzip --strip-components=1 --directory=./offline-kit --file=./immuta-enterprise-*.tgz immuta-enterprise/DIGESTS.md
Open file
./offline-kit/DIGESTS.md
. This file includes the name and digest of every container image referenced by the Helm chart.Download each image listed in file
DIGESTS.md
using skopeo. Each image will be saved to directoryoffline-kit
with the filename<name>-<tag>.tar
.read -r -p "Enter the container image to download (e.g., docker.io/hello-world:latest):" image && \ skopeo copy docker://"$image" docker-archive:"offline-kit/$(sed 's#.*/##; s#:#-#g' <<< "$image").tar"
Transfer artifacts
This section demonstrates how to push the previously archived container images to a private registry that's accessible from within your air-gapped environment.
Transfer directory
offline-kit
(created in the previous section) onto a machine that's within your air-gapped environment.Push each image to your private registry using skopeo.
skopeo copy docker-archive:offline-kit/<name>-<tag>.tar docker://<private-registry-fqdn>/immuta/<name>:<tag>
Chart installation
Edit the immuta-values.yaml
to reference the private container registry and images.
