Private or offline installation¶
Domino provides bundles of offline installation media for use when running the
fleetcommand-agent without Internet
access to upstream sources of images and charts. To serve these resources, you must have a Docker registry accessible to
You can find URLs of available offline installation bundles in the
fleetcommand-agent release notes. These bundles
can be downloaded via cURL with basic authentication. Contact your domino account team for credentials.
Note that there is one file required: a versioned collection of images.
curl -u username:password -#SfLOJ https://mirrors.domino.tech/s3/domino-artifacts/offline/fleetcommand-agent-docker-images-v29-4.2.0.tar
Extracting and loading¶
The images bundle is a
.tar archive that must be extracted before being used.
tar -xvf fleetcommand-agent-docker-images-v29-4.2.0.tar
fleetcommand-agent-docker-images bundle there will be:
- a collection of individual Docker image
domino-load-images.py is a script to ingest the
images.json metadata file and load the associated Docker images
for a specific Domino version into the given remote Docker registry.
To load images into your private registry, run
domino-load-images.py and pass in the URL of your registry as an
argument. The script expects to run in the same directory as the
images.json metadata file and the
python domino-load-images.py your-registry-url.domain:port
Once images have been loaded into your private registry you’re ready to install Domino.
To install Domino using a custom registry, the image references must be modified to reference the upstream registry. Use
--image-registry argument on the
init command to modify all image references to the external registry.
docker run --rm -v $(pwd):/install quay.io/domino/fleetcommand-agent:v29 \ init --image-registry your-registry-url.domain:port --full --file /install/domino.yml
If your registry requires authentication, ensure the
private_docker_registry section of your installer configuration
is filled in with the correct credentials:
private_docker_registry: server: your-registry-url.domain:port username: '<username>' password: '<password>'
Charts come pre packaged within the
Set up the
helm object in configuration to match the following:
helm: version: 3 host: gcr.io namespace: domino-eng-service-artifacts prefix: '' username: '' password: '' tiller_image: gcr.io/kubernetes-helm/tiller:v2.16.1 # Version is required and MUST be 2.16.1 insecure: false cache_path: '/app/charts'
Note that the
http protocol before the hostname in this configuration is important. Once these changes have been
made to your installer configuration file, you can run the
fleetcommand-agent to install Domino.
When performing offline installations there are 3 main central configuration keys that need to be repointed to the private registry hosting the referenced images. From the Domino landing page, click Admin in the main menu. Then in the administration portal, click Advanced > Central Config. Use the Add Record button at top right to add the following records:
