Download this Image

The image is available on

docker pull


For full instructions on how to run cert-exporter, please refer to the upstream GitHub repositories documentation.

NOTE: cert-exporter is intended to run inside a Kubernetes cluster. If you attempt to run locally, it’ll hang and doesn’t print anything to the logs.


To deploy via helm, please refer to the upstream helm charts documentation for comprehensive instructions, which includes supported parameters.

Below is an example of how to use the helm chart, overriding the image with the chainguard image:

helm repo add cert-exporter

# The chart will error if this doesn't already exist, however it does not use this ns directly.
kubectl create namespace monitoring

helm install cert-exporter cert-exporter/cert-exporter  \
 --set \
 --set image.tag=latest
