In air-gapped deployments where there is no access to the public Docker registries Sonobuoy supports running end-to-end tests with custom registries. This enables you to test your air-gapped deployment once you’ve loaded the necessary images into a registry that is reachable by your cluster.
Just provide the
--e2e-repo-config parameter and pass it the path to a local
YAML file pointing to the registries you’d like to use. This will instruct the
Kubernetes end-to-end suite to use your registries instead of the default ones.
sonobuoy run --e2e-repo-config custom-repos.yaml
The registry list is a YAML document specifying a few different registry categories and their values:
dockerLibraryRegistry: docker.io/library e2eRegistry: gcr.io/kubernetes-e2e-test-images gcRegistry: k8s.gcr.io etcdRegistry: quay.io/coreos privateRegistry: gcr.io/k8s-authenticated-test sampleRegistry: gcr.io/google-samples
The keys in that file are specified in the Kubernetes test framework itself. You may provide a subset of those and the defaults will be used for the others.
The list of custom registries is consumed by the Kubernetes end-to-end tests, but outside of that there are 2 images you will need to be able to access:
To get those images into your cluster you need to pull/tag/push those images yourself:
PRIVATE_REG=<private registry> SONO_VERSION=<version of Sonobuoy you are targeting; e.g. v0.14.0> CLUSTER_VERSION=<version of k8s you are targeting; e.g. v1.14.0> docker pull gcr.io/google-containers/conformance:$CLUSTER_VERSION docker pull gcr.io/heptio-images/sonobuoy:$SONO_VERSION docker tag gcr.io/google-containers/conformance:$CLUSTER_VERSION $PRIVATE_REG/conformance:$CLUSTER_VERSION docker tag gcr.io/heptio-images/sonobuoy:$SONO_VERSION $PRIVATE_REG/sonobuoy:$SONO_VERSION docker push $PRIVATE_REG/conformance:$CLUSTER_VERSION docker push $PRIVATE_REG/sonobuoy:$SONO_VERSION
If you want to run the systemd_logs plugin you’ll need to pull/tag/push it as well. In addition, you’ll have to manually specify the image you want to use via
sonobuoy gen ->
kubectl apply since that image is not overridable on the CLI. The default value is:
If you do not wish to run it in your air-gapped cluster, just remove it from the list of plugins to be run (again, using
sonobuoy gen ->
