Crazy at it sounds, some Kubernetes installations don't have access to Internet and source all their images from an internal registry. sync-to-internal-registry.jsonnet is a jsonnet snippet that helps with the task of pushing upstream images used by the prometheus operator to an internal registry by printing the right docker pull/tag/push commands. $ jsonnet -J vendor -S --tla-str repository=internal-registry.com/organization sync-to-internal-registry.jsonnet docker pull quay.io/coreos/addon-resizer:1.0 docker tag quay.io/coreos/addon-resizer:1.0 internal-registry.com/organization/addon-resizer:1.0 docker push internal-registry.com/organization/addon-resizer:1.0 docker pull quay.io/prometheus/alertmanager:v0.15.2 docker tag quay.io/prometheus/alertmanager:v0.15.2 internal-registry.com/organization/alertmanager:v0.15.2 docker push internal-registry.com/organization/alertmanager:v0.15.2 ...
