To ensure the integrity of all runtime container images published and downloaded for production systems, image signing support is now available for all Apigee hybrid images using Docker Hub. All hybrid runtime images are publicly available for download from the Google Docker Hub account.
Hybrid images are signed with Docker Content Trust, a feature that lets users verify the integrity and publisher of every image built and running in a Docker registry. These signatures allow client-side or runtime verification of specific image tags against publisher keys, ensuring that the image is exactly what the publisher created and pushed for publication.
Download signed container images
If you are using a Kubernetes cluster without internet access to deploy your hybrid runtime services, you will need to download the container images to a local container registry and then access the registry from your Kubernetes cluster.
To download a signed container image, you should have Docker
installed and use the
docker pull command as follows. Be sure to append the correct tag
to each image name. For example, the tag for
as shown below.
docker pull google/apigee-mart-server:1.1.1
docker pull google/apigee-synchronizer:1.1.1
docker pull google/apigee-runtime:1.1.1
docker pull google/apigee-authn-authz:1.1.1
docker pull google/apigee-cassandra-client:1.1.1
docker pull google/apigee-cassandra-backup-utility:1.1.1
docker pull google/apigee-cassandra:1.1.1
docker pull google/apigee-udca:1.1.1
docker pull google/apigee-stackdriver-logging-agent:1.6.8
docker pull google/apigee-prom-prometheus:v2.9.2
docker pull google/apigee-stackdriver-prometheus-sidecar:release-0.4.0
docker pull google/busybox:1.30.1
Verify container image signer and signatures
To verify that an image has been signed, run the following command:
docker trust inspect --pretty $IMAGE_NAME:$IMAGE_TAG
The output of this command will let you know whether the tagged image is signed, the name of the signers, and a list of signers and keys. For example:
docker trust inspect --pretty google/apigee-mart-server:1.1.1
