phires/prometheus-certcheck repository overview

Exposes certificate expiration information in prometheus compatible format under /metrics. Default is listing on port 8080, can be overridden by env $ADDRESS Checks every 60 minutes by default, can be overridden by env $INTERVAL

Mount a path with a "hosts" file to /config containing all hosts to be queried, one per line and including the port. E.g.:

$ cat ~/config/hosts
google.com:443

$ docker run -v ~/config:/config phires/prometheus-certcheck:latest

Usually you'll want to use this container in Kubernetes and mount a configmap as hosts file.
